Puttin’ on the Ritz and improving well-being with older adults through virtual music theatre

<p>Digital programming and virtual interactions, initially considered to be stop-gap measures during the first few waves of the pandemic, may now be an important part of supporting many people’s health and well-being — including the well-being of older adults.</p> <p>During the COVID-19 pandemic, group musical activities moved online, prompting a wave of <a href="https://ericwhitacre.com/the-virtual-choir">virtual choir</a> experiments and <a href="https://www.youtube.com/watch?v=5rzZ2F18MwI">virtual orchestra</a> offerings.</p> <p>These and other online communities weren’t limited to students. A <a href="https://www150.statcan.gc.ca/n1/pub/45-28-0001/2021001/article/00027-eng.htm">Statistics Canada survey</a> found that more than half of Canadians between the ages of 64 and 74 increased their participation in online activities during the pandemic by connecting with family and friends through video conferencing, or accessing entertainment online.</p> <p>Virtual opportunities in the <a href="https://doi.org/10.1371/journal.pone.0252956">performing arts are ripe with potential</a> for older adults to foster skills and creativity, and to improve well-being.</p> <h2>Social connection</h2> <figure><figcaption> </figcaption>Going digital serves many purposes, the most important of which may be social connection.  Since <a href="https://doi.org/10.1080/23748834.2020.1788770">connecting with others</a> remains important for older adults, this can be achieved through, or in addition to, virtual leisure or entertainment opportunities.</figure> <p>Our research has revealed that <a href="https://storage.googleapis.com/wzukusers/user-20563976/documents/598184972c66407e9334c5df1b37bb91/Renihan%2C%20Brook%2C%20Draisey-Collishaw.pdf">virtual music theatre — music theatre online — allows for a more accessible and a less exclusive way to engage with this art form</a> with many benefits for participants.</p> <h2>Online performing arts</h2> <p>The performing arts allow performers and audiences to feel, be creative in community, express themselves and communicate or play through song, movement or storytelling.</p> <p>Benefits associated with participation in the arts include <a href="https://apps.who.int/iris/handle/10665/329834">improved mood and well-being</a> and sense of <a href="https://www.pbs.org/parents/thrive/turn-to-the-arts-to-boost-self-esteem">belonging</a>.</p> <p>Research has also documented associations between seniors’ participation in the arts and improved <a href="https://doi.org/10.1159/000499402">mobility</a> and <a href="https://doi.org/10.1016/j.archger.2018.02.012">vocal health</a>.</p> <p>Before the pandemic erupted, we had started leading a program, <a href="http://www.riseshinesing.ca/">Rise, Shine, Sing!</a>, that created opportunities for local citizens typically excluded from the creation of music theatre due to age, ability and access. The program was mostly attended by older adults, some with Parkinson’s Disease or other chronic conditions.</p> <figure><iframe src="https://www.youtube.com/embed/59MTQnoi2hU?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">A trailer for the ‘Rise, Shine, Sing!’ program.</span></figcaption></figure> <p>We held three weekly face-to-face sessions from the end of February 2020, until mid-March, and then moved the program online (via Zoom) for 12 sessions from April until June 2020. The program continues to be offered, with many participants indicating a preference to continue virtually.</p> <p>Somewhat to our surprise, when the program moved online, the fact that participants could only hear the facilitator and themselves singing was not a deterrent to participating. Participants enjoyed singing, dancing and creating characters using costumes and props based on cues and feedback from facilitators.</p> <h2>Paradigm shift for music theatre</h2> <p>Virtual music theatre presents a serious paradigm shift for the genre. Most of the time when people think of music theatre, they think of live bodies moving in perfect synchrony <a href="https://www.americantheatre.org/2022/02/04/what-can-be-said-with-and-about-broadway-dance/">to choreographed movement</a>, and voices singing in perfect harmony while performers are physically present together.</p> <p>Researchers have examined how group singing and movement fosters togetherness, <a href="https://doi.org/10.1057/s41599-020-00549-0">community</a> and <a href="https://doi.org/10.3389/fpsyg.2014.01096">social bonding</a>.</p> <p>Music theatre has made strides to become more inclusive over the course of the 21st century. <a href="https://www.deafwest.org/">Los-Angeles based Deaf West Theatre</a>, for example, creates works of music theatre that can be experienced and performed by members of the Deaf and hearing communities.</p> <figure><iframe src="https://www.youtube.com/embed/k08lV8GO43w?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">ASL version of ‘We Don’t Talk About Bruno,’ from Disney’s ‘Encanto’ with Deaf West.</span></figcaption></figure> <p>A multitude of new works, stagings and casting practices are highlighting and supporting the experiences of marginalized groups, by <a href="https://www.blackoperaalliance.org/">diversifying</a> and <a href="https://doi.org/10.3390/arts9020069">queering</a> the field, for example.</p> <p>Such works offer resistance and new stories to an industry that has traditionally been ableist, white and ageist.</p> <p>But despite a healthy <a href="https://global.oup.com/academic/product/beyond-broadway-9780190639525?cc=ca&amp;lang=en&amp;">community music theatre scene</a> in North America, most opportunities still leave out many people due to issues related to social anxiety, experience, mobility, family life and/or finances.</p> <h2>Music theatre meets universal design</h2> <p>We drew on the intersection of <a href="https://muse.jhu.edu/article/629960/pdf">music theatre performance</a> and <a href="https://www.cast.org/impact/universal-design-for-learning-udl">universal design for learning</a> to develop a model where success could look different from person to person.</p> <p>In terms of the movement, participants could synchronize with the facilitator and/or other members of the group. They were equally welcome and encouraged to customize or adapt their movements to suit their own needs and interests.</p> <p>We embraced dancing from both a seated and standing position, to explore different levels and to accommodate different mobility capabilities. Participants controlled how much they shared by deciding how visible they wanted to be on camera.</p> <h2>Classics and newer numbers</h2> <p>We drew on musical classics or standards from <a href="https://www.britannica.com/topic/Singin-in-the-Rain-film-1952"><em>Singin’ in the Rain</em></a>, the <em>Sound of Music</em>, <a href="https://www.thestar.com/entertainment/stage/2022/08/23/joseph-and-the-amazing-technicolor-dreamcoat-coming-to-toronto-as-a-test-run-for-possible-broadway-revival.html"><em>Joseph and The Amazing Technicolour Dreamcoat</em></a> — as well as newer numbers from <em>Wicked</em> and other popular songs.</p> <figure class="align-left zoomable"><figcaption></figcaption></figure> <p>We also <a href="http://www.riseshinesing.ca/glow.html">co-created our own songs</a> by combining our shared memories or inspirations through image, lyrics and movements to explore themes of joy and resilience in difficult times.</p> <p>While the program was led virtually, before sessions, leaders dropped off or mailed prop boxes to all participants. These were filled with costumes including small scarves and ribbons that could be used for choreography.</p> <h2>Promise of virtual musical theatre</h2> <p>Virtual music theatre has shown incredible promise, even in the short time we have been exploring it. Digital connections reframe being together at the same time and in the same space. This adds new unexpected dimensions to <a href="https://doi.org/10.1111/j.1749-6632.2012.06530.x">making music in a group</a>.</p> <p>First, goals and expectations of uniformity are replaced with goals of individual empowerment and creative exploration.</p> <p>Second, participants remain committed to the community and group endeavour, but are also free to tailor and adapt the ways they engage with the material and with one another. If group members invite friends or family in other cities to participate virtually, as some in our group did, the virtual community also expands in meaningful ways.</p> <p>Finally, participants can also adjust their personal comfort by sharing as much or little of themselves with the group without feeling like they are letting the group down.</p> <h2>Our hybrid future</h2> <p>The pandemic catalyzed the need for virtual interaction. While we know that <a href="https://doi.org/10.1093/occmed/kqab041">Zoom fatigue</a> is pervasive, virtual opportunities for music theatre participation and creation offer a new paradigm of artistic experience.</p> <p>These opportunities also offer striking promise for bringing performers some of the <a href="https://doi.org/10.3389/fpsyg.2019.00778">same benefits</a> as in-person music theatre experiences.</p> <p>In some cases, they also facilitate new access to music in community, and allow participants to engage with the art form and one another in ways that support personal agency and independence, while also maintaining social connection and interactivity. <a href="https://www.lyrics.com/lyric/6358131/George+Gershwin/I+Got+Rhythm">Who could ask for anything more</a>?<!-- Below is The Conversation's page counter tag.

A robot dog with a virtual spinal cord can learn to walk in just one hour

<p>We’ve all seen those adorable clips of newborn giraffes or foals first learning to walk on their shaky legs, stumbling around until they finally master the movements.</p> <p>Researchers wanted to know how animals learn to walk and learn from their stumbling, so they built a four-legged, dog-sized robot to simulate it, according to a new study <a href="https://www.nature.com/articles/s42256-022-00505-4" target="_blank" rel="noreferrer noopener">reported</a> in <em>Nature Machine Intelligence</em>.</p> <p>They found that it took their robot and its virtual spinal cord just an hour to get its walking under control.</p> <p>Getting up and going quickly is essential in the animal kingdom to avoid predators, but learning how to co-ordinate leg muscles and tendons takes time.</p> <p>Initially, baby animals rely heavily on hard-wired spinal cord reflexes to co-ordinate muscle and tendon control, while motor control reflexes help them to avoid falling and hurting themselves during their first attempts.</p> <p>More precise muscle control must be practised until the nervous system adapts to the muscles and tendons, and the young are then able to keep up with the adults.</p> <p>“As engineers and roboticists, we sought the answer by building a robot that features reflexes just like an animal and learns from mistakes,” says first author Dr Felix Ruppert, a former doctoral student in the Dynamic Locomotion research group at the Max Planck Institute for Intelligent Systems (MPI-IS), Germany.</p> <p>“If an animal stumbles, is that a mistake? Not if it happens once. But if it stumbles frequently, it gives us a measure of how well the robot walks.”</p> <figure class="wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"> <div class="wp-block-embed__wrapper"> <div class="entry-content-asset"> <div class="embed-wrapper"> <div class="inner"><iframe title="Learning Plastic Matching of Robot Dynamics in Closed-loop Central Pattern Generators" src="https://www.youtube.com/embed/LPL6nvs_GEc?feature=oembed" width="500" height="281" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div> </div> </div> </div> </figure> <p><strong>Building a virtual spinal cord to learn how to walk</strong></p> <p>The researchers designed a <a href="https://cosmosmagazine.com/health/machine-learning-tool-brain-injury/" target="_blank" rel="noreferrer noopener">learning algorithm</a> to function as the robot’s spinal cord and work as what’s known as a Central Pattern Generator (CPG). In humans and animals, the CPGs are networks of neurons in the spinal cord that, without any input from the brain, produce periodic muscle contractions.</p> <p>These are important for rhythmic tasks like breathing, blinking, digestion and walking.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p198628-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/robot-machine-learning-to-walk/#wpcf7-f6-p198628-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page spai-bg-prepared" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>The CPG was simulated on a small and lightweight computer that controlled the motion of the robot’s legs and it was positioned on the robot where the head would be on a dog.</p> <p>The robot – which the researchers named Morti – was designed with sensors on its feet to measure information about its movement.</p> <p>Morti learnt to walk while having no prior explicit “knowledge” of its leg design, motors, or springs by continuously comparing the expected data (modelled from the virtual spinal cord) against the sensor data as it attempted to walk.</p> <p> “Our robot is practically ‘born’ knowing nothing about its leg anatomy or how they work,” Ruppert explains. “The CPG resembles a built-in automatic walking intelligence that nature provides and that we have transferred to the robot. The computer produces signals that control the legs’ motors and the robot initially walks and stumbles.</p> <p>“Data flows back from the sensors to the virtual spinal cord where sensor and CPG data are compared. If the sensor data does not match the expected data, the learning algorithm changes the walking behaviour until the robot walks well and without stumbling.”</p> <p>Sensor data from the robot’s feet are continuously compared with the expected touch-down data predicted by the robot’s CPG. If the robot stumbles, the learning algorithm changes how far the legs swing back and forth, how fast the legs swing, and how long a leg is on the ground.</p> <p>“Changing the CPG output while keeping reflexes active and monitoring the robot stumbling is a core part of the learning process,” Ruppert says.</p> <p>Within one hour, Morti can go from stumbling around like a newborn animal to walking, optimising its movement patterns faster than an animal and increasing its energy efficiency by 40%.</p> <p>“We can’t easily research the spinal cord of a living animal. But we can model one in the robot,” says co-author Dr Alexander Badri-Spröwitz, head of the Dynamic Locomotion research group.</p> <p>“We know that these CPGs exist in many animals. We know that reflexes are embedded; but how can we combine both so that animals learn movements with reflexes and CPGs?</p> <p>“This is fundamental research at the intersection between robotics and biology. The robotic model gives us answers to questions that biology alone can’t answer.”</p> <p><!-- Start of tracking content syndication.

<p dir="ltr">Archeologists have recreated a Pompeiian villa that was destroyed by the eruption of Mount Vesuvius in 79 C.E.</p> <p dir="ltr">Through the use of VR (virtual reality), researchers have carefully created a digital model of the ancient residence to better understand how visitors would have seen the home, according to <a href="https://www.cambridge.org/core/journals/antiquity/article/reviewing-pompeian-domestic-space-through-combined-virtual-realitybased-eye-tracking-and-3d-gis/E82035C72C580D9602CCF00D625BC65D">the recently published paper in the </a><a href="https://www.artnews.com/t/archaeology/">archaeology</a> journal Antiquity.</p> <p dir="ltr">The villa, known as the House of the Epigrams, was excavated in the 1870s and so named because it contains mythical paintings accompanied by Greek epigrams.</p> <p dir="ltr">While the identity of the owner is impossible to determine, researchers have suggested it may have belonged to a Lucius Valerius Flaccus due to a signet ring bearing his sigil being discovered there.</p> <p dir="ltr">The paper, titled “Re-viewing Pompeian domestic space through combined virtual reality-based eye tracking and 3D GIS,” was written by PhD. candidate Danilo M. Campanaro and Professor Giacomo Landeschi, who are both affiliated with the Department of Archaeology and Ancient History, Lund University, Sweden.</p> <p><iframe title="YouTube video player" src="https://www.youtube.com/embed/9t39at8xgLw" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p> <p dir="ltr">Through extensive research, the authors of the paper have been able to determine what decorations to use in the recreation, as well as uncovering how the opulent villa would be viewed by residents of Pompeii of various social and economic classes. </p> <p dir="ltr">This recreation is the first of its kind in the studies of ancient Pompeii, with the research findings showcasing a different quality of life for locals before their city was destroyed. </p> <p dir="ltr"><em>Image credits: YouTube</em></p>

Daunted by therapy? Virtual reality could be the answer

<p><span style="font-weight: 400;"> If opening up to a therapist seems like a near-impossible task, new research shows that you’re not the only one - and proposes a new option that could soon be available.</span></p> <p><span style="font-weight: 400;">A study from Edith Cowan University, published in </span><em><a rel="noopener" href="https://www.frontiersin.org/articles/10.3389/frvir.2021.750729/full" target="_blank"><span style="font-weight: 400;">Frontiers in Virtual Reality</span></a></em><span style="font-weight: 400;">, found that 30 percent of people surveyed would rather talk about negative experiences with a virtual reality (VR) avatar than a real-life person.</span></p> <p><span style="font-weight: 400;">Researchers created a ‘realistic motion avatar’ that appeared similar to its real-life counterpart, then compared the social interactions between people talking to the avatar versus a real person.</span></p> <p><span style="font-weight: 400;">Participants then rated their experience on factors such as enjoyment, comfort, awkwardness, perceived understanding, and how much they think they disclosed about themselves.</span></p> <p><span style="font-weight: 400;">Dr Shane Rogers, a psychology and communication researcher involved in the study, said participants found VR and face-to-face interactions to be quite similar in all but one way.</span></p> <p><span style="font-weight: 400;">“Overall, people rated VR social interaction as similar to face-to-face interaction, with the exception of closeness, where people tended to feel a little closer with each other when face-to-face,” Dr Rogers </span><a rel="noopener" href="https://www.scimex.org/newsfeed/virtual-reality-could-help-make-therapy-easier" target="_blank"><span style="font-weight: 400;">said</span></a><span style="font-weight: 400;">.</span></p> <p><span style="font-weight: 400;">“This technology has the potential for broad application across a number of areas such as casual conversation, business, tourism, education and therapy,” he said.</span></p> <p><span style="font-weight: 400;">“The study found that 30 percent of people preferred disclosing negative experiences via VR. This means that therapy might be opened up to new people who don’t feel comfortable with traditional face-to-face interactions.”</span></p> <p><img style="width: 500px; height:281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7846832/vr1.jpg" alt="" data-udi="umb://media/b6881ee566e74d5ba66c6e6a0c91129a" /></p> <p><em><span style="font-weight: 400;">Virtual reality has been used in video games for several years now, but new research shows it can also be used in mental health settings. Image: Getty Images</span></em></p> <p><span style="font-weight: 400;">Though VR has been around for several years, the new research is among several new studies and initiatives applying the technology to treat mental health conditions.</span></p> <p><span style="font-weight: 400;">In the United States, veterans with Post-Traumatic Stress Disorder (PTSD) are being treated with the assistance of VR, which can transport them back to traumatic experiences - even if they struggle to remember the event or other details.</span></p> <p><span style="font-weight: 400;">The tech has also been used in “empathy training”, where clinicians wear VR headsets to better understand what patients in their care are experiencing, particularly for veterans with dementia or older LGBTQ veterans.</span></p> <p><span style="font-weight: 400;">“Now what you hear and what you see in front of your eyes is the same thing as a patient who’s experiencing dementia or an LGBTQ vertan who’s ageing,” Anne Lord Bailey, a pharmacist and director of clinical tech innovation involved in the scheme, told </span><em><a rel="noopener" href="https://fedtechmagazine.com/article/2021/12/how-va-using-vr-veterans-therapy-perfcon" target="_blank"><span style="font-weight: 400;">FedTech</span></a></em><span style="font-weight: 400;">.</span></p> <p><span style="font-weight: 400;">“All of a sudden, people start talking to you and what you hear is muddled, or your vision doesn’t see what you should be seeing. It looks distorted, or I can’t hear things because they’re not clear, even though I can tell that people are talking to me. Or, I get disoriented: I try to turn to the right, and things are shifty or crooked.”</span></p> <p><span style="font-weight: 400;">Meanwhile, the UK NHS launched a treatment plan last year using VR to treat patients with trypanophobia, or a phobia of needles, ahead of their Covid vaccinations. Patients are treated by being exposed to scenarios such as a medical waiting room or blood draw, to help therapists treat patients’ fears in a controlled environment.</span></p> <p><span style="font-weight: 400;">“VR is very effective at bridging the gap between real-life exposure and what the patient feels able to do at the time they enter treatment,” Vanessa Dodds, a cognitive behavioural therapist involved in the UK program, told </span><a rel="noopener" href="https://www.medicaldevice-network.com/news/needle-phobia-vr/" target="_blank"><span style="font-weight: 400;">Medical Device Network</span></a><span style="font-weight: 400;">.</span></p> <p><span style="font-weight: 400;">Dr Rogers echoed this sentiment, adding that improvements in the technology will improve its affordability and accessibility as a treatment option - with applications beyond therapy as well.</span></p> <p><span style="font-weight: 400;">“It might also enable therapists to conduct therapy more effectively at a distance, as a person can be in the therapist room (in virtual reality) while seated in their own home,” he said.</span></p> <p><span style="font-weight: 400;">“More powerful computers are becoming more affordable, VR headsets are continuing to develop, and more user-friendly VR interaction software platforms are becoming more available and being updated.”</span></p> <p><span style="font-weight: 400;">Following the work by Dr Rogers and his colleagues, future steps will involve more investigation of how different aspects of the avatar affect user experience, as well as how VR can be used in therapeutic settings.</span></p> <p><em><span style="font-weight: 400;">Image: Getty Images</span></em></p>

Centenarian's priceless reaction to virtual tour of childhood town

<p>A 100-year-old grandmother has broken down in tears while exploring her hometown in Armenia through the use of a virtual reality headset.</p> <p>The woman, who now lives in the US, became emotional while using VR to take a tour around her hometown of Vagharshapat - something she never thought she would do again.</p> <p>Upon seeing the Etchmiadzin Cathedral that she used to visit as a child, she was hit by a wave of emotion and started to tear up.</p> <p>The woman's granddaughter, Michelle, captured the heart-warming moment and shared it on TikTok, where it racked up over three million views in just a few days.</p> <p>Michelle captioned the video, "Showing my 100-year-old Armenian grandma the Etchmiadzin Cathedral in virtual reality," that shows her grandmother, whom they call Nene.</p> <div class="embed"><iframe class="embedly-embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2F7034663525347953967&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40shmellywelly%2Fvideo%2F7034663525347953967%3Flang%3Den%26is_copy_url%3D1%26is_from_webapp%3Dv1&amp;key=59e3ae3acaa649a5a98672932445e203&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" scrolling="no" title="tiktok embed" frameborder="0" allow="autoplay; fullscreen" allowfullscreen="true"></iframe></div> <div class="embed">Nene dons the extravagant VR headset while her family members instruct her to look around, as they follow what she is seeing on their own screen.</div> <p>Suddenly, Nene becomes emotional, as someone behind the camera asks, "Why are you crying?"</p> <p>"It's so beautiful," she responds, attempting to wipe away her tears with a tissue.</p> <p>The breathtaking Etchmiadzin Cathedral is often considered the oldest cathedral in the world, and a shrine for Armenian Christians.</p> <p>The comments on Michelle's video were flooded by people praising the sweet gesture, as one person said, "This is what VR should be used for."</p> <p>Another commenter noted, "She went from a time when televisions didn't exist to VR in her living room.

Antarctica without windchill, the Louvre without queues: how to travel the world from home

<p>SpaceX’s recent <a href="https://theconversation.com/spacexs-historic-launch-gives-australias-booming-space-industry-more-room-to-fly-139760">Falcon 9 rocket launch</a> proves humanity has come leaps and bounds in its effort to reach other worlds. But now there’s a quicker, safer and environmentally friendlier way to travel to the centre of the galaxy – and you can do it too.</p> <p><a href="https://chandra.harvard.edu/photo/2020/gcenter/">NASA</a> has co-developed a free virtual reality (VR) adventure providing 500 years of travel around the black hole at the centre of the Milky Way. The experience is available to download from two major VR stores, <a href="https://store.steampowered.com/app/1240350/Galactic_Center_VR/">Steam</a> and <a href="https://www.viveport.com/21f8b24c-783b-4af2-8e81-a63a14553721">Viewport</a>, in a non-collapsed star system near you.</p> <p>And this kind of spacefaring may be the tip of the iceberg when it comes to the potential of virtual travel and tourism.</p> <h2>The virtual travel bug</h2> <p>Simply speaking, VR refers to technology that immerses users in a computer-generated world that removes them from reality. Augmented Reality (AR), however, aims to superimpose virtual imagery over a user’s view of the real world. Pokémon Go is a popular AR game.</p> <p><span>VR-based tourism has a longer history than you might think. In the 1850s, it involved staring at </span><a href="https://www.loc.gov/pictures/collection/stereo/background.html">stereographs</a><span> with a </span><a href="https://www.smithsonianmag.com/innovation/sterographs-original-virtual-reality-180964771/">stereoscope</a><span>. With this invention, viewers looked at slightly different images through each eye, which were then assembled by the brain to make a new image providing the illusion of spatial depth (in other words, a 3D effect).</span></p> <p>A century later, 1950s <a href="https://en.wikipedia.org/wiki/Cinerama">Cinerama</a> widescreen viewing inspired cinematic travel though its large, curved screens and multiple cameras.</p> <p>The 1960s <a href="https://www.engadget.com/2014-02-16-morton-heiligs-sensorama-simulator.html">Sensorama</a> foretold a shiny future of multimodal immersive cinematic experiences, playing 3D films with sound, scents and wind to immerse users. In <a href="https://www.vrs.org.uk/virtual-reality/history.html">VR circles</a>, Ivan Sutherland became famous for inventing the head-mounted display, as well as augmented reality (AR).</p> <p>Travel restrictions under COVID-19 <a href="https://www.ft.com/virtualtravel">present an opportunity</a> for virtual reality travel to finally take off.</p> <p>In an era of lockdowns and social distancing, we could use VR to travel to remote, distant or even no longer existing places. Remote tourism is here (the <a href="https://www.remote-tourism.com/">Faroe Islands</a> offers a great example), and interest in VR tourism is <a href="https://www.forbes.com/sites/solrogers/2020/03/18/virtual-reality-and-tourism-whats-already-happening-is-it-the-future/#5b39a26228a6">blossoming</a>.</p> <h2>VR comes in many forms</h2> <p>The word “virtual” can refer to an immersive 3D experience, but also 360° panorama photographs and movies (a <a href="https://wiki.panotools.org/Panorama_formats">cylinder, sphere or cube of photographs</a>).</p> <p>What is deemed “virtual” varies greatly across different devices and platforms. Let’s look at some of the ways this term is applied.</p> <p><strong>Desktop virtual environments</strong>: these are computer-based 3D environments on a flat screen, without the spatial immersion of VR platforms.</p> <p><strong>Cinematic VR</strong>: these are phone-based panoramic environments. Many desktop experiences of 360° movies or images can be conveyed in low-cost <a href="https://arvr.google.com/cardboard/">stereoscopic VR through smartphones</a>. Google Street view can be viewed in <a href="https://www.blog.google/products/google-vr/get-closer-look-street-view-google-earth-vr/">Google VR</a> on Android and <a href="https://3g.co.uk/guides/what-smartphones-work-with-virtual-reality">some Apple</a> smartphones, but it’s not real VR.</p> <p><strong>Head-mounted displays</strong>: HMDs such as <a href="https://www.instructables.com/id/How-to-make-Google-Cardboard/">Google Cardboard</a> and <a href="https://arvr.google.com/daydream/smartphonevr/">Google Daydream</a> are what many people think of when they hear “virtual reality”. Some HMDs are self-contained, not requiring connection to a computer or console. Arguably, the market is <a href="https://3dinsider.com/oculus-vs-htc-vive-vs-psvr/">dominated</a> by the Oculus range owned by Facebook, the HTC Vive range, and PlayStation VR.</p> <h2>VR in a pandemic</h2> <p>In a post-coronavirus age, device sharing is problematic. HMDs aren’t easy to clean and VR software can quickly become obsolete, with new headsets sometimes not running two-year-old software. Users also have to deal with costly updates, eyestrain, and having to share displays that sat on someone else’s face.</p> <p>Developing and sharing content across different devices can be a nightmare but there are increasingly <a href="https://www.vrtourviewer.com/">simple</a> and effective ways to create <a href="https://www.pocket-lint.com/ar-vr/news/google/142054-google-arcore-android-s-equivalent-to-apple-arkit-explained">AR</a> and VR content, despite a bewildering range of platforms and equipment (there are more than <a href="https://www.archives.gov/files/applied-research/ncsa/8-an-overview-of-3d-data-content-file-formats-and-viewers.pdf">140 3D file formats</a>).</p> <p>Despite this, many VR projects are not preserved – including <a href="https://www.mdpi.com/2071-1050/11/8/2425">virtual heritage</a>projects!

Virtually unknown ALDI checkout rule confounds shoppers

<div class="post_body_wrapper"> <div class="post_body"> <div class="body_text redactor-styles redactor-in"> <p>Many shoppers at ALDI are confused about a virtually unknown rule that was shared on Facebook.</p> <p>Over the last week, several shoppers have shared their confusion over ALDI's refusal to allow shoppers to purchase alcohol if they have a minor with them.</p> <p>ALDI policy states that a customer can be denied the sale of alcohol if a child under the age of 18 is accompanying them or if a minor has handled alcohol they intend to buy.</p> <p>One shopper was unaware of the rule and claimed he was stopped from purchasing Vodka Cruisers for his wife as he had his teenage daughters with him.</p> <p>Another shopper said the same thing happened to her, as she was refused service after her 18-month-old toddler touched a bottle at the checkout.</p> <p>“I did and had my 18-month-old daughter with me,” said the shopper.</p> <p>“I was holding her on my hip and she leant over and touched the alcohol on the conveyer while I was loading other groceries on.”</p> <p>Another claimed she was denied service in the presence of her underage son.</p> <p>“I was refused because I was buying a carton and had my son carry it because I have a bad back,” the shopper said.</p> <p>The German supermarket has confirmed with <a rel="noopener" href="https://7news.com.au/lifestyle/food/the-little-known-aldi-checkout-rule-that-has-many-scratching-their-heads-c-1390041" target="_blank" class="editor-rtflink"><em>7News</em></a> that the policy of the supermarket is in line with Australian laws.</p> <p>“As a responsible retailer, ALDI Australia supports and adheres to all regulations for the purchase of alcohol including Responsible Service of Alcohol (RSA),” said an ALDI Australia spokesperson.</p> <p>“Under the Liquor Control Reform Act 1998, it is an offence to supply alcohol to a person under the age of 18 and for a person under the age of 18 to purchase or receive alcohol.</p> <p>“The sale of alcohol can be refused if a minor has handled alcohol that could be potentially purchased by an adult for the minor’s consumption.</p> <p>“This also extends to a minor accompanying an adult purchasing alcohol, even if the minor has not physically touched an alcoholic product.</p> <p>“It is the store’s responsibility to refuse any customer who presents a risk and ultimately it is at the discretion of the person serving alcohol to decline the sale should they have any doubts or concerns.</p> <p>“There are severe consequences for breaching laws and policies set in place by the Australian government involving the sale of alcohol.</p> <p>“As such, ALDI faces heavy penalties should we sell alcohol to any customer who supplied to a person under the age of 18.”</p> </div> </div> </div>

Haunting photos of teen sent to family in “virtual kidnapping” scam

<p>Investigations are continuing after a teenage student was in a “virtual kidnapping” scam in Sydney, which resulted in more than $213,000 being transferred for their child’s safe return.</p> <p>NSW Police received reports of a missing 18-year-old Chinese woman on September 8 after friends became concerned for her welfare.</p> <p>Photos and videos of the woman were sent to family using the Chinese messaging service WeChat.</p> <p>Large sums of money were demanded by a person that was pretending to be Chinese police who were promising her safe release.</p> <p>Following further investigations from NSW Police, Chinese authorities and the AFP, the woman was found safe and unharmed in the inner-city suburb of Pyrmont on September 15.</p> <p>Police have since raided a Chatswood unit, while a 22-year-old male has spoken with officers. Investigations continue.</p> <p>In one photo, a pair of bare legs can be seen.  Police were trying to determine if that person is a victim themselves or involved in the scam.</p> <p>NSW Police Force state crime command director Detective Chief Superintendent Darren Bennett said police were urging the community to remain vigilant to such elaborate phone scams.</p> <p>“Less than two months ago, the NSW Police Force issued a warning to the community about ‘virtual kidnapping’ scams targeting Chinese students studying in Australia,” Det Chief Supt Bennett said.</p> <p>“It appears these scammers are continuing to operate and are once again preying on the vulnerabilities of individuals in the community who are not in direct physical contact with their families.”</p> <p>Det Chief Supt Bennett said that this incident began in July when a woman received an email from someone who was posing as Chinese police.</p> <p>They told her that her personal details had been illegally used on a package intercepted overseas.</p> <p>“The individuals behind these ‘virtual kidnapping’ scams continually adapt their scripts and methodology which are designed to take advantage of people’s trust in authorities,” he said.</p> <p>Police are reminding Chinese nationals that authorities in China would never contact students demanding money.</p> <p>They have urged that if anyone experiences such behaviour to report to the Chinese Consulate in Sydney and police.</p>

Duchess Kate surprises schoolchildren in a virtual assembly

<p>The Duchess of Cambridge has surprised young students across the United Kingdom by popping in virtually to lead their online assembly.</p> <p>The Duchess spoke with students from Waterloo Primary Academy in Blackpool as part of the special assembly for Oak National Academy, an online classroom founded in response to the coronavirus lockdown.

Small acts of kindness can go such a long way.”</p> <p>She also asked the students what kindness meant to them, with the answers ranging from “sharing” to “[treating] people how you want to be treated”.</p> <p>Matt Hood, principal at Oak National Academy thanked the Duchess for her virtual appearance.</p> <p>“We’re thrilled that The Duchess of Cambridge was able to lead this week’s assembly on acts of kindness. Being kind and considerate is a vital lesson for children at any time, but especially so in the current pandemic,” he said.</p> <p>“We must encourage young people to talk about their feelings and to know that it’s normal to feel a bit anxious or upset right now.”</p>

The problem with virtual reality is endless possibilities

<p>Just a few years ago, virtual reality (VR) was being showered with very real money. The industry raised an estimated US$900 million in venture capital in 2016, but by 2018 that figure had <a href="https://content.fortune.com/wp-content/uploads/2019/06/vir_graphic_01.png">plummeted to US$280 million</a>.</p> <p><a href="https://www.oculus.com/?locale=en_US">Oculus</a> - the Facebook-owned company behind one of the most popular VR headsets on the market - <a href="https://www.businessinsider.com.au/how-facebooks-oculus-go-santa-cruz-headsets-plan-to-make-vr-mainstream-2017-10">planned to deliver 1 billion headsets to consumers</a>, but as of last year had <a href="https://www.businessinsider.com.au/mark-zuckerberg-facebook-oculus-vr-bet-taking-longer-than-expected-2019-10?r=US&amp;IR=T">sold barely 300,000</a>.</p> <p>Investments in VR entertainment venues all over the world, VR cinematic experiences, and specialised VR studios such as <a href="https://atap.google.com/spotlight-stories/">Google Spotlight</a> and <a href="https://www.ccpgames.com/">CCP Games</a> have either significantly downsized, closed down or morphed into new ventures. What is happening?</p> <p>Recent articles in <a href="https://fortune.com/longform/virtual-reality-struggle-hope-vr/">Fortune</a> and <a href="https://www.theverge.com/a/virtual-reality">The Verge</a> have voiced disdain with VR technology. Common complaints include expensive, clunky or uncomfortable hardware, and unimaginative or repetitive content. Sceptics have compared VR experiences to the 3D television fad of the early 2010s.</p> <p>As a VR researcher and developer, I understand the scepticism. Yet I believe in this technology, and I know there are “killer apps” and solutions waiting to be discovered.</p> <p>Last week, Western Sydney University hosted a <a href="https://vrst.acm.org/vrst2019/">global symposium on VR software and technology</a>, at which academics and industry partners from around the world discussed possible ways forward for VR and augmented reality. Among the speakers were Aleissia Laidacker, director of Developer Experience at <a href="https://www.magicleap.com/">Magic Leap</a>; University of South Australia computing professor <a href="https://people.unisa.edu.au/Mark.Billinghurst">Mark Billingurst</a>; and Tomasz Bednarz, director of UNSW’s <a href="https://artdesign.unsw.edu.au/research/epicentre-expanded-perception-interaction-centre">Expanded Perception and Interaction Centre</a>.</p> <p><strong>Virtual reality, literal headache</strong></p> <p>One problem discussed at the symposium is the fact that VR experiences often cause health-related issues including headaches, eye strain, dizziness, and nausea. Developers can partially deal with these issues at the hardware level by delivering balanced experiences with high refresh and frame rates.</p> <p>But many developers are ignoring usability guidelines in the pursuit of exciting content. Gaming industry guidelines used by <a href="https://docs.unrealengine.com/en-US/Platforms/VR/DevelopVR/ContentSetup/index.html">Epic</a>, <a href="https://developer.oculus.com/design/latest/concepts/book-bp/">Oculus</a>, <a href="https://blog.marvelapp.com/designing-vr-beginners-guide/">Marvel</a>, and <a href="https://software.intel.com/en-us/articles/guidelines-for-immersive-virtual-reality-experiences">Intel</a> recommend that games completely avoid any use of induced motion, acceleration or “fake motion”, which are often the main cause of discomfort and motion sickness.</p> <p>Yet the vast majority of available VR experiences feature some kind of induced motion, either in the form of animation or by basing the experience on user movement and exploration of the virtual environment.</p> <p>I have met many first-time VR users who generally enjoyed the experience, but also reported “feeling wrong” – similar to enjoying the clarity of sound in noise-cancelling headphones but also having a “strange sensation” in their ears.</p> <p><strong>Killing creativity</strong></p> <p>Queasiness is not the only turnoff. Another problem is that despite the near-limitless potential of VR, many current offerings are sorely lacking in imagination.</p> <p>The prevailing trend is to create VR versions of existing content such as games, videos or advertisements, in the hope of delivering extra impact. This does not work, in much the same way that radio play would make terrible television.</p> <p>A famous cautionary tale comes from <a href="https://secondlife.com/">Second Life</a>, the virtual world launched in 2003 which <a href="https://gigaom.com/2013/06/23/second-life-turns-10-what-it-did-wrong-and-why-it-will-have-its-own-second-life/">failed spectacularly to live up to its billing</a>. Real-world businesses such as Toyota and BMW opened branches in Second Life, allowing users to test-drive badly programmed versions of their virtual cars. They <a href="https://www.smh.com.au/technology/few-lives-left-for-second-life-20080821-gdsrna.html">lasted mere months</a>.</p> <p>Why would we prefer a humdrum virtual experience to a <a href="https://theconversation.com/why-virtual-reality-cannot-match-the-real-thing-92035">real one</a>? No one needs a virtual Toyota. We need to give users good reasons to leave their reality behind and immerse themselves in a new one.</p> <p>There have been some notable successes. <a href="https://beatsaber.com/">Beat Saber</a>, made by Czech indie developers, is the one of the few games that have explored the true potential of VR – and is the only VR game to have grossed more than US$20 million.<span class="caption"></span></p> <p>The <a href="https://www.youtube.com/watch?v=9CPVOt7QjcM">VR Vaccine Project</a> helps to take the sting out of childhood needles, by combining a real-world vaccination with a superhero story in the virtual world, in which the child is presented with a magical shield at the crucial moment.</p> <p>I really hope VR is on its way to becoming more mainstream, more exciting, and less underwhelming. But we scientists can only present new technological solutions, to help make VR a more comfortable and enjoyable experience. Ultimately it is down to VR developers to learn from existing success stories and start delivering those “killer apps”. The possibilities are limited only by imagination.<!-- Below is The Conversation's page counter tag.

Do you really need a VPN for your smartphone?

<p>Virtual private networks (known in geek speak as VPNs) were first used to provide a secure connection for remote workers to corporate networks.</p> <p>Now they're often used to access geo-blocked streaming services such as the US version of Netflix. A VPN provides an encrypted conduit to allow users to securely send/receive data.</p> <p>Recently, they've being marketed toward smartphone users, with the main aim to protect people when using public wi-fi rather than geo-blocking.</p> <p>But do you really need one? Well, that depends on how much you value your privacy and access to free internet.</p> <p>Most public wi-fi networks are not encrypted which means others on the same network can eavesdrop on your web browsing.</p> <p>Using the Wireshark utility at a hotel I recently stayed at, I was able to view the online activities of fellow guests also connected to the hotel's wi-fi.</p> <p>Symantec has just released its VPN app, called Norton WiFi Privacy, which is available for both iOS and Android. It costs $49.95 a year.</p> <p>According to Symantec's Australasian territory manager, Mark Gorrie, the app has advantages over offerings from lesser known competitors.</p> <p>"Norton WiFi Privacy does not impose data limits or advertisements on users as a trade-off for services."</p> <p>The app detects when your smartphone/tablet connects to an unsecured network, encrypting data and diverting it through a secure connection. </p> <p>Anyone snooping should only see a stream of gibberish.</p> <p>However, the app adds a small amount of delay into the mix. This was because I was connected to a range of Symantec VPN servers located around the world.</p> <p>So is it worth the $49.95 a year?</p> <p>If you use a mobile device for sensitive correspondence over public wi-fi a lot, it is probably a good idea. </p>

Curing phobias with virtual reality

<p>You can't move. Your hands are immobilised on the arms of a chair as the masked dentist leans closer, his drill shrieking.</p> <p>Sound like your worst nightmare? It's OK: you're safe in virtual reality.<br /> <br /> Dentist drills, spiders, needles and heights- people can now be treated for their phobias with virtual reality.<br /> <br /> The scenario is part of the treatment program at Australia's first specialist, virtual-reality phobia treatment clinic, which recently opened in Sydney.<br /> <br /> Also on the menu: a doctor waiting to stab a huge needle into your forearm and slowly suck out your blood. That's soon to be joined by scenarios involving spiders, heights, scary animals and social situations.</p> <p>"In the past the way that therapists would do therapy is they would get someone to imagine they were in the scenario. Here we can really bring that situation to life," says Pieter Rossouw, manager at the <span style="text-decoration: underline;"><strong><a href="https://www.sydneyphobiaclinic.com.au/">Sydney Phobia Clinic.</a></strong></span></p> <p>"If you put on that headset, you're a patient sitting in the dentist chair, and the dentist is coming at you with the drill. And you can hear the noise. Everyone always pulls their head back."</p> <p>Rossouw recently gave the needle simulation to one of his patients to try, and says the reaction shows VR tech is now good enough to be convincingly terrifying for phobia-sufferers.</p> <p>"It took her about 15 minutes just to approach the table the needle was on."</p> <p>The scenarios are designed to be as accurate as possible and were built with the consultation of medical specialists.</p> <p>Phobias are traditionally treated by teaching a patient coping mechanisms, and then gradually exposing them to the source of their fear. For spiders, a patient might build up to a visit to the zoo.</p> <p>But many people have phobias that are difficult for psychologists to expose them to, Rossouw says. </p> <p>That's where VR comes in. Patients use commercially available headsets coupled with proprietary simulations built by the clinic.</p> <p>Guided by a psychologist they can gradually expose themselves to their fear. The first exposure might be using the headset's controller to walk into the dental surgery, a big step for some; later they can watch someone else undergo the procedure before braving it themselves.</p> <p>People fear dental work in part because they cannot see what the dentist is doing inside their mouth. The software's ability to let a patient watch someone else undergoing the procedure is helpful for that, Rossouw says.</p> <p>The emergence of cheap consumer VR headsets has the potential to give sufferers the tools to treat themselves at home, says University of Melbourne VR researcher Dr Greg Wadley.</p> <p>Consumer VR's rapid recent growth – Facebook released a headset in March, Google has one coming this month – means the technology's potential is ahead of the science.</p> <p>"The quality is really good, they are quite cheap, they are likely to be in consumers hands over the next few years. There is clearly potential in them, but the potential has not been explored. It's in the process."</p> <p>Scenarios involving spiders – so many spiders, crawling all over you – heights, public transport and crowds are being tested or are already available to download and use.</p> <p>Meanwhile a large number of research groups are investigating potential uses for the new technology.</p> <p>A London-based project for example is exploring using train-station simulations to treat social anxiety. The simulated patrons can even be programmed to turn and stare at the user – helpful for treating paranoia.</p> <p>But Rossouw says DIY tools are no match for proper clinical treatment.</p> <p>"It's critical the client is given skills and psycho-education to be able to handle the exposure sessions and get the most out of them," he says.</p> <p>"Most people know that facing their fears is how to overcome them, but they lack the skills to do so effectively."</p> <p><em>First appeared on <span style="text-decoration: underline;"><a href="https://www.stuff.co.nz/" target="_blank"><strong>Stuff.co.nz.</strong></a><br /></span></em></p>
