U.S. highway workers suffer tens of thousands of injuries and 1,000 of them die every year. Over time, even sounds designed to keep them safe become monotonous. And that is the moment when fatal accidents happen, says Namgyun Kim, assistant professor department of civil and environmental engineering at the University of Dayton.

Virtual software Kim designed is proving successful when it comes to increasing their safety awareness. The Texas-based construction company Webber tested his program on its workers. Now that Kim is at UD, he will reach out to local crews.

In the scenario Kim demonstrated for WVXU at UDs new Intelligent Infrastructure Lab, workers are asked to clean up. Holding a real broom, Kim watches his virtual self at a construction site. A front loader is moving back and forth and at some point, sounds an alarm when it's getting close.

Our system knows, 'Oh this guy doesnt pay attention to surrounding hazards and then the accident will happen,' he says. The worker then virtually sees and feels the impact.

To maximize this effort, Kim explains, we developed a wireless electronic stimulus system so we are going to add additional feedback during the accident, and we believe that will increase the effect of this safety training system.

Kim says there are hundreds of safety training systems. So, what makes this one different besides the fact it's virtual? He says it can measure a worker's physical movement, eye movement and pupil dilation elements safety managers can analyze to figure out how well workers behave in dangerous situations.

The university's new Intelligent Infrastructure Lab Manager Jack Hui Wong is thrilled about all the things this virtual space can do.

This whole lab is very exciting, very new and also very powerful," he says. "We can do a lot of different research. For example, some application in psychology we are going to do some human physical interaction in this virtual environment.

One example is investigating how people interpret distance in virtual space so it can be accurate in physical space. Kim looks forward to developing other safety software scenarios for firefighters, manufacturers and electricians.

Robert Liang is UDs department chair for civil engineering. His students are using the Intelligent Virtual Lab to build buildings.

This will open up so many opportunities for different disciplines, researchers to conduct their research and to advance their field of science, he says.

The Intelligent Infrastructure Engineering Lab was dedicated in August.

Highway workers got a dose of virtual reality to help keep them safe - WVXU

NEEDHAM, Mass.--(BUSINESS WIRE)--Worldwide shipments of Augmented Reality (AR) headsets are forecast to decline 8.7% year over year to nearly 260,000 units by the end of 2022, according to new data from the International Data Corporation (IDC) Worldwide Quarterly Augmented and Virtual Reality Headset Tracker. While a decline for such a nascent technology may seem abrupt, volumes have been slowing in recent quarters due to the shaky financials of some of the top companies, lack of new devices, and end-user demand being fulfilled by AR on smartphones in the short term.

In the first half of 2022, the top 5 AR headset makers were Microsoft, Rokid, Shadow Creator, Mad Gaze, and RealWear. However, the landscape is expected to shift dramatically as more companies enter the market and tech giants like Apple and Meta take more of an interest in AR. Looking ahead, despite the decline in 2022, IDC anticipates plenty of growth as the market is forecast to have a 5-year compound annual growth rate (CAGR) of 70.3%, topping out at 4.1 million units by the end of 2026.

"We're still years away from mass consumer adoption of AR glasses, and the earliest timeframe for such products would be in late 2024 or early 2025 as companies such as Apple, Meta, and others use what they've learned from virtual reality headsets to launch a more streamlined and consumer friendly design for AR glasses," said Jitesh Ubrani, research manager Mobility and Consumer Device Trackers at IDC. "Between now and then, AR will continue to grow within the consumer segment though most of the products will be more akin to goggles or headsets rather than glasses and that will be a non-starter for many."

"The majority of AR headset shipments to date have been on the commercial side, where companies are willing and able to make the necessary investments in not just the hardware but also the required software and services that can drive a clear return on investment," Tom Mainelli, group vice president, Device & Consumer Research. "We expect commercial shipments to drive the market well into the forecast period, as more companies embrace AR's growing number of use cases."

A graphic illustrating IDC's 2021-2026 forecast for AR headsets is available by viewing this press release on IDC.com.

IDC Tracker Sees a Long Road Ahead for Augmented Reality Headsets - Business Wire

A hard plastic case that exploded on the campus of Northeastern University in Boston causing minor injuries to a staff member contained a rambling note that railed against virtual reality and also referenced Facebook founder Mark Zuckerberg, a law enforcement official said Wednesday.

Investigators are still trying to identify the motive behind the Tuesday evening explosion and are working to understand why the package was specifically sent to Northeastern, the official said.

Investigators are also trying to determine the specific mechanism of the device and whether the package contained any gunpowder, the official added. The official could not discuss details of the investigation publicly and spoke to The Associated Press on condition of anonymity.

The official described the case as a Pelican-style case. Pelican makes hard cases designed to protect sensitive equipment.

A spokesperson for the FBI office in Boston declined to comment Wednesday, saying the investigation is still very active and fluid.

A Northeastern spokesperson on Wednesday had no new details on the case.

The package delivered to Holmes Hall detonated just after 7 p.m. Tuesday when a staff member opened it, the university said in a statement. The staff member, a 45-year-old man, was taken to the hospital with minor injuries to his hand, police said. No name was made public.

Boston's bomb squad neutralized a second package near the city's Museum of Fine Arts, which is near Northeastern's campus.

Holmes Hall is home to the university's creative writing program and its women's, gender and sexuality studies program.

Northeastern is a private university in downtown Boston with about 16,000 undergraduate students. The campus opened normally for classes Wednesday.

Tuesday's explosion marked one of the first big scares in Boston since 2013, when two bombs planted near the finish line of the Boston Marathon killed three spectators and wounded more than 260 others.

Virtual Reality (VR) Headset Market Projected to Hit USD 57.65 Billion at a 28.50% CAGR by 2030 - Report by Market Research Future (MRFR) -...

CHARLESTON, W.Va.--(BUSINESS WIRE)--Starting this fall, students at the University of Charleston, West Virginia (UCWV) will study human anatomy in 3D, with the launch of a dedicated virtual reality (VR) lab, through a partnership with Perspectus, Inc., a Colorado-based virtual and mixed reality technology firm.

We are excited to offer virtual reality technology to enhance student learning, shared University of Charleston President Marty Roth. As soon as we experienced the Perspectus demo, we knew this would be a gamechanger for core courses like Anatomy and Physiology, and in specialized healthcare programs like Nursing, Radiology, and Physician Assistant. The three-dimensional, highly customizable imaging dramatically enhances students depth of understanding. And we can work with our hospital and other healthcare partner organizations to integrate content students will see in their clinical rotations, externships, and other applied learning settings, thereby providing better career preparation.

Completed in August 2022, the UCWV lab is one of the most advanced VR Education Labs in the country, featuring 30 high-powered computers with high resolution headsets to access the Perspectus VR technology. The lab will have a soft launch this fall and eventually be used in multiple programs by Spring 2023, including Biology, Radiologic Science, Nursing and Physician Assistant programs.

Perspectus VR allows users to enter a virtual world where they can manipulate anatomical structures and view them from every angle and enlarged to any size. Layers of muscle, blood vessels, and bones can be added, removed, marked on, or shaded in different colors to show their interrelated parts. Users can also render patient radiology images, such as an MRI or CT scans, to view them in true 3D.

No matter how accurate a textbook or digital image is, there will always be a breakdown in communication and understanding when students are shown two-dimensional versions of three-dimensional structures. Perspectus VR solves this problem by showing images as they appear in nature - eliminating the need to translate the data, says Erick Miranda, Chief Operating Officer of Perspectus. During early testing at Colorado State University in Fort Collins, Perspectus VR increased understanding of spatial relationships and anatomical systems for 87% of students.

We are continually exploring the latest technological innovations that can enhance student learning and move our students to the forefront of their area of study, added University of Charleston CIO Scott Terry. With this new VR lab, were not only helping our students build the critical reasoning necessary to provide quality care, were preparing them for a future where technology will improve the access to and quality of healthcare and medicine.

University of Charleston is the largest & fastest-growing private, non-profit institution of higher education in the state of West Virginia. Based in Denver, Colorado, Perspectus, Inc. is the industry leader in VR, using its patented software platform to provide VR solutions to higher education, healthcare and commercial users.

Perspectus and The University of Charleston Offer Next Generation Virtual Reality Education Lab - Business Wire

The coronavirus pandemic plunged millions of Americans into the virtual world. Across the country, schools and businesses used virtual means to keep moving forward.

The South Texas VA was no exception: Spinal Cord Injury & Disorder (SCI/D) has also embraced virtual technologies to better treat their specialized patients. The technology it adopted was the Neuro Rehab Virtual Reality (VR) XR Therapy System, part of a larger plan to better serve SCI/D patients.

As we started our journey of a successful transition from a 10 employees service to a 115 employees SCI/D Neuro Rehab service care line in the last 15 months, we have been actively seeking avenues to offer innovative cutting-edge technology to our Veterans, said Dr. Divya Singhal, chief of Spinal Cord Service.

Singhal said it wouldnt have been possible without Anne Bailey, Pharm D and director for Clinical Tech Innovation in the Office of Healthcare Innovation and Learning, advocating for this VR therapy and facilitating the process.

Singhal partnered with recreation therapy on a pilot to introduce VR for leisure therapy. The feedback was positive across the board, including one Veteran who reinforced the decision he made to be in the Army and not wear Air Force blue.

I like flying the airplane, said Chad Stuart, an Army Veteran who has been in SCI/D for several months following an accident. I was horrible when I first started, I crashed a lot.

Stuart enjoyed his hands at flying. He also said there are opportunities to solve mysteries or even move into a house.

After attending a VA summit focused on VR, Singhal was sold, and knew she wanted to integrate active intense acute rehabs like physical, occupational and recreational rehabilitations. VR was the tool to make that happen. After acquiring a system, she now needed volunteers, and that didnt take long.

Dr. Singhal asked me if I wanted to demo something, and when Dr. Singhal asks, I usually say yes, Stuart said.

Stuart met with physical therapist Dr. Carla Torrents Gabaldon for their first session that integrated VR into treatment on August 25. He liked it so much, he came back for another session. That next day, Gabaldon set him up with a program that challenges his sitting balance by throwing out colorful notes that are synced to music that he is supposed to collect with two handheld wands.

After several minutes, he mastered that task and wanted to move onto something else more challenging. Singhal says the great thing about this mode of therapy is that each Veteran competes against their own abilities. Whats really neat is that the complexity level changes as the person progresses, Singhal said.

Physical therapy student Ashlyn Koslovsky supports Veteran Stuart through a series of virtual reality exercises.

Stuart wanted to put the work in, so Gabaldon used an iPad to dial up the next challenge for the eager Veteran. She chose a practical application which simulates an individual completing their grocery shopping, a task many just take for granted, but which for an SCI/D patient poses many challenges.

That is one very challenging grocery shopping module, said Stuart. You are having to go on your left side and use your right hand to reach over continuously.

A bystander could judge the level of effort by the amount of wobble he had while sitting upright. Physical therapy student Ashlyn Koslovsky was there to guide and keep him on track.

The difficulty level didnt dissuade Stuart from completing all shopping tasks.

Its very challenging for me to do that one, Stuart said, brushing off the fact he had to rely on Koslovsky for a little help. I still need that therapist support, but my core is getting stronger and Im able to sit up unsupported.

These activities are all by design, as Gabaldon explained.

We hope that by incorporating VR into our treatments, we are able to make them more salient for our patients and applicable to everyday life at discharge, like the grocery shopping exercise and rhythm exercise module, Gabaldon said.

Singhal said treatment goals are multi-facetedphysiological as well as psychological. She added that the VR platform is very flexible, allowing providers to offer therapies based on the Veterans specific interests and needs.

Stuart is living proof of the psychological benefits.

While describing the process of getting his first wheelchair and the multiple surgeries that kept him on bedrest for more than four months, he mentioned it kept him away from many of the activities he enjoyed, including VR, and that got him down.

It was tough because I was on bedrest so much, you cant really do VR laying down, Stuart said. He now gets to utilize VR even more, first working with recreation therapist Cheryl Kelley, who introduced him to VR, and now added treatments with Gabaldon, who works with him five days a week.

Army Veteran Chad Stuart participates in virtual reality during his physical therapy treatment.

When Stuart first began using a standing frame, which allows patients with paralysis or paresis to achieve a standing position, he would experience a significant rise in heart rate due to his anxiety with supported standing after being on bed rest and in a wheelchair for so long. At times, he would reach the maximum levels within the targeted therapeutic range for his heart rate, causing the therapists to have to return the patient to sitting.

Like Singhal alluded to earlier, the therapists engaged with VRs psychological benefits, to correct a physiological problem. The problem the therapists faced was allowing Stuart to continue to challenge himself while maintaining safety. These measures are critical to patient safety and the organizations high reliability principles.

Then the therapists had an idea: send him to Paris.

The VR system can bring the user to multiple locations in interactive environments. Stuart chose Paris, and he enjoyed watching couples stroll through a Parisian Park. Remarkably, Stuart was able to maintain stable vitals, without significant increases, when using the VR in conjunction to the standing frame. Being a fan of the beach, Stuart then moved on to an Australian beach and moved along the water. His vitals continued to maintain within stable, therapeutic levels.

I think my favorite was the beach, he said. It was kind of talking to me, telling me when to breathe and telling me to watch the waves coming in. That one was good. I felt really calm.

This concept is actually called Extended Reality (XR), and it is a term to describe environments that combine the real and the virtual worlds, like walking through a grocery store or strolling on the beach.

Gabaldon says the system provides her treatment flexibility, as she is able to address two things at oncea patients anxiety (through Relaxation mode) while completing functional treatments, such as the standing frame.

Stuart is excited about continuing his therapies and put in a solid 90 minutes of training.

I felt it was a good workout when I was done in there, Stuart said. Even before I got into the standing frame, it wears me out, but its good. I like that.

Stuarts motivation is sourced from his lengthy stay, but he is also aware that he has more work to do. Of course, I want to go home, but I dont want to leave here until I have taken advantage of every opportunity, he added.

Stuart said he advocates for the technology because he feels it has played a huge role in his recovery process.

One of the things I like about it is that its like recess, because you get to get away from here, Stuart said. You know I dont want to see another hospital, but the VR, it allows me to kind of step away.

Singhals vision means Stuart is not off the hook yet.

My vision is being able to engage Veterans after they leave the hospital and maximize the potential for an optimal recovery, Singhal said. It can enhance their wellbeing, staying engaged with therapists and most importantly serving as an important addition to part of the wellbeing in between clinic visits.

Virtual reality: Veteran on virtual trips around the world - VA News - Veterans Affairs (.gov)

MALDEN, MA A Malden dancer will soon feature in what organizers describe as an experimental augmented reality dance experience centered in Cambridges Kendall Square Canal District.

Dubbed Emotive Lands, the performance is a product of the arts collective The Click. Anyone can access the performance via a corresponding app available from Oct. 1 through Nov. 30. There will also be a live performance where artists will interact with the digital, augmented reality Emotive Lands content along the water in the Canal District on Oct. 1 at 1 p.m.

Audience members can access the app, once it is available, via The Clicks website, via the Apple App Store, the Google Play Store, or via other app vendors.

Audience members will be able to go to the Canal District, either during the live launch show or at any other time during the apps availability to view the augmented reality show around them. Viewers who download the app and open it near Kendall Square will see visual prompts that will lead them to spots where they can see virtual dancers on their screens. Dancers will interact with various physical objects in the environment as part of the show.

The app uses technology that is somewhat similar to technology seen in massively popular games like Pokemon Go.

At least nine local artists are involved in the Emotive Lands project, including Maldens Alexandria Nunweiler, who appears in some aspects of the app.

The overlap of AR technology and the arts is pretty small right now, but it's growing, app developer James Peerless said in a press release announcing this project. Its a way to bring the feeling of being at a live performance in an on-demand way.

We want people to see the power of community when engaging with this work, dancer Kristin Wagner added.

Our work is heightened by the creative freedom that technology offers audience members are free to come and go at any time, Wagner later continued.

Emotive Lands is backed by a series of grants and residency programs.

The Click dates back to 2021 and is marking its first project as a group with the launch of Emotive Lands.

The Click's Emotive Lands app and live performance are both free.

The live performance will begin at 15 Broad Canal Way in Cambridge and follow a walking path along the Charles River with several stops.

A rain date is set for Oct. 2.

Malden Dancer Part Of Upcoming Augmented Reality Dance Project - Patch

Duration judgments

The sun was a constant component of the environment and was designed to move with either its natural speed on the horizon or to not move at all. Participants completed 8 trials in total, 6 minutes each, and were not informed of the fact that trials were of equal length, nor of the number of trials they would complete. Moreover, throughout the experiment participants listened to ambient sounds of sea waves and wind through headphones.

We experimentally manipulated the level of immersion by asking participants to complete the task in both a non-immersive and an immersive environment, in front of the LCD monitor or with the head mounted device (HMD) respectively. In order to probe the effect of cognitive load, as in the original study, in half of the trials participants were asked to complete the classical n-back task30. These experimental conditions amount to 2 (immersion) 2 (sun movement) 2 (cognitive load) design. At the end of each trial, participants were asked to estimate the duration of the time of the passed trial in seconds, following Schatzschneider et al. 2016 design. At the beginning and the end of the experimental session participants were also asked to complete a Simulator Sickness Questionnaire (SSQ), the change of this score is used as Simulator Sickness Score. To test the effects of each experimental condition we run a 2 2 2 Repeated measures ANOVA, with the Simulator Sickness Score as a covariate in a separate run. Results were adjusted for multiple comparison with a Bonferroni correction where needed.

First, we tested the effect of the manipulation of the sun. In the original study authors found that when no task was executed, participants estimated the time to be longer when the sun was still than when it moved at its natural speed. We found no significant effect of the manipulation of the speed of the movement of the sun on time estimation (F(1,36) = 0.103, p = 0.750, Fig. 1A) even when we look only at the condition with no-task (two-tailed t(36) = 0.191, p = 1, adjusted for multiple comparisons, Fig. 2). To make sure that the effect was not inhibited by the unpleasant simulator effect we included the score as a covariate to the ANOVA analysis. Although adding the SSQ score improves fit of the model, (residuals(full + SSQ) < residuals (full), where residual = data fit), it has no significant effect on the sun, immersion, or interaction between sun and immersion.

Mean duration estimation for each experimental condition. Error bars indicate SEM. We found no significant effect of sun (A) nor immersion (C). We found a significant effect of cognitive load (B). Post-hoc tests indicated that subjects estimated time to be shorter in the condition with an n-back task compared to the condition with no task (t(36)=8.307, p=6.876e10,d=0.59).

Mean estimation as an interaction between the sun and cognitive load. We did not replicate the effect from the original study.

We replicated the classical cognitive load result11 and found a significant effect of the task on trial duration estimation (F(1,36) = 69.013; p = 6.874e-10, p2= 0.657). Post-hoc test revealed duration estimation to be shorter when participants performed a task than when they were passively present in the environment (t(36) = 8.307, p = 6.876e10,d = 0.59, Fig. 1B).

Schatzschneider et al.28 reported shorter duration estimation in non-immersive (LCD) than in immersive (HMD) environments. We did not replicate this result and no effect of the environment was found on duration estimation (F(1,36)=0.588; p=0.448, Fig.1C), however, we found a significant interaction between cognitive load and immersion (F(1,36)=6.854; p=0.013, (upeta _{P}^{2} = 0.16))when no task was assigned participants estimated time to be longer in an immersive environment, but when participants performed a task, they estimated the duration to be longer in a non-immersive environment (Fig.3A). We initially thought that this is again a cognitive load effectin immersive environment participants were exposed to fewer distractors and could focus on the task more, and engage more cognitive resources. However, performance was slightly higher in the LCD condition (paired t(73)=2.7156, p=0.0083, Fig.3A inset). In light of these results, we hypothesize that HMD was somehow a more challenging environment. In the non-immersive environment, in the condition with no task, participants were exposed to the rest of the experimental room, which resulted in a more complex environment as opposed to the HMD condition where only the virtual island could be observed.

(A) Mean estimation as interaction between immersion and cognitive load. Inset Performance (sensitivity index A) during the n-back task for the two immersion levels. (B) Average time estimation over the course of the experiment, regardless the experimental condition. In gray label shuffled permutation, shaded area represents standard deviation. (C) Scatter plot of the mean duration estimation during HMD trials and the SSQ score. Each dot represents one participant.

Although negative simulator symptoms did not specifically affect the effect of the sun on time estimation, we tested whether it had any effect on average time estimation. To assess the statistical significance of this relationship we regressed the SSQ score on duration estimation measurements. The SSQ score explained a significant amount of the variance of the duration estimation (F(1,294) = 9.590, p = 0.002,R = 0.178,R2 = 0.032). The regression coefficient (B = 3.765,95%,CI = [1.372,6.156]) indicated that an increase in SSQ score by 1 increased, on average, the duration estimation by 4 seconds (Fig. 3C). We hypothesize that this effect of aversive simulator sickness symptoms, like nausea or vertigo, is mediated by the link between physiological arousal and time perception. It has previously been shown that various types of arousal affect interval timing4,5,6, especially unpleasant stimuli dilate time perception31. Although Schatzschneider et al.28 also collected SSQ responses, they did not provide analysis beyond score change.

As stated above, we did not replicate the effect of immersion on time duration estimation. Although the effect reported in the original paper was not significant, it did appear as a strong trend, at least for conditions with a task. In the original paradigm, participants had always started with a non-immersive block and continued onto an immersive block. Such a linear design is confounded by fatigue. At the beginning of the experiment, participants may estimate the duration to be shorter just because they are less tired than at the end, so we hypothesize that this is the reason we did not replicate the immersion effect reported by Schatzschneider et al.28. In our design, we controlled for this effect by randomizing the immersion blocks. Whatever the condition with which participants have started or finished the experiment, they estimated the time to be shorter at the beginning of the experiment than at the end (Fig. 3B) with a transient constricting effect of the environment change mid-experiment.

Non-significant results of frequentist tests do not discriminate between absence of evidence and evidence of absence. To test our ability to present evidence in favor of the null hypothesis (no effects of sun movement on time perception) we went beyond the frequentist approach, turned to Bayesian Inference, and conducted Bayesian Repeated ANOVA and separate Bayesian Paired-Sample t-tests for each condition. We first conducted a Bayesian Repeated Measures ANOVA on the data with the experimental conditions [immersion (2) task (2) sun (2)] as within-subjects factors. We used the default prior options for the effects (i.e., r = 0.5 for the fixed effects). To assess the robustness of the result, we also repeat the analysis for two different prior specifications (details in the ''Methods'' section). Analysis of effects indicates moderate to strong evidence for exclusion of immersion (BFexcl = 4.803, where BFexcl is the change from prior to posterior exclusion odds for model-averaged results, our notation follows JASP manual), sun (BFexcl = 16.815), and all interactions between the two. In fact, only the model with a single cognitive load term had BFexcl smaller than 1 (BFexcl = 3.724e13). Post-hoc tests indicated robustness of these findings to prior width (Figs. 4, S2). We can therefore conclude that in our data we can observe moderately strong evidence for no effect of the manipulation of sun or immersion on duration estimation.

Results of the post-hoc Bayesian paired sample t-test between the two levels of sun manipulation. On the left, the effect size as a function of the prior and posterior density. In the middle BF10 as a function of tested prior. On the right, accumulation of evidence towards H0 as a function of the number of samples (participants).

The Joys and Horrors of Virtual Reality in Anime

Weve talked in the past about the intersection of virtual reality and anime, and for good reason. VRand related fields like AR and the concept of a metaversehave long been mainstays of sci-fi and genre fiction. But as these things become more real and accessible, our perception of it changes. And so does animes.

Today, were looking back across the history of VR in anime: the good, the bad, and the in-between. Just like the real world, the virtual world has its share of both good and bad, and anime isnt shy about exploring both.

In the modern age, wed likely classMacross Plus idol Sharon Apple as more of an AR/AI hybrid than virtual reality. But her virtual idol status still holds true. The computerized songstress won the hearts and minds of the localswhich wasnt always a good thing. When her programming went haywire, so did the traditional love geometry of the franchise.

VR and AR have been used to much better (and safer) effect in later iterations ofMacross, including Sheryl and Rankas stunning live shows inMacross Frontier. I guess they learned things stay a lot calmer when the talent is organic.

In 1999,Martian Successor Nadesico andSilent Mbius creator Kia Asamiya asked the ultimate question: What if there were magical girls in virtual reality? The result wasCorrector Yui, an original anime series in which a computer-illiterate teen becomes a magical virus hunter.

Taking place in the year 20XX (yes, really),Corrector Yui posits the existence of ComNet: the VR-based evolution of the Internet. Both ComNet and the real world are under threat from an evil Host computer called Grosser. Eight antivirus programs exist to fight Grosser, but they need someone to command them. And that someone is Yuior rather,Corrector Yui. Her magical girl powers exist only within ComNet, where she leads the eight programs to save the virtual and real worlds.

Hot and fresh from SCIENCE SARU, the team behindDEVILMAN crybabyandKeep Your Hands Off Eizouken!, is a virtual reality series that hits way closer to home. Tom Sawyer Island, the world whereYUREI DECO takes place, feels much more within reach than other anime. Both AR and VR are a part of life here, thanks to either ocular implants or special glasses. The currency is Love: literally, social media likes. The world is colored by AR, and you can dive into one of many hyperverses for work, school, and games. Oh, and a customer service center oversees the whole thing.

WhileYUREI DECO challenges this lifestyle and its resulting drawbackscensorship and ignorance of the plight of others, for exampleit also gives credit to the great things technology gives us. Thanks to the tech of Tom Sawyer Island, the elderly Madam 44 can be an action hero. Extinct animals can be brought back to life in a virtual zoo. AR avatars can let you appear on the outside how you feel on the inside. In short, technology justis: its what you do with it that matters.

The Buddy test system measures VR and AR headsets with up to six degrees of freedom.

Optofidelity, the Finnish manufacturer of screen measurement systems, developed what is probably one of the nightmare-fueling test platforms ever, Buddy. Attached to a jet-black robotic platform is a (partial) model human head with a proprietary vision module that tests virtual reality headsets and augmented reality glasses.

With a headset placed on the model, two cameras in the artificial skull imitate eyes. An advanced version of the system handles tests in all six degrees of freedom. Buddys best design to date is capable of examining many headset parameters with full freedom of movement.

Numerous axes enable the systems testing versatility. The frame slides sideways on a floor rail, rotates around its axis, and raises and lowers the artificial head. This imitates free movements that real headset users also perform: forward/backward, up/down, left/right, nodding, rolling, and yawing (turning sideways).

The main areas of application are development departments and production lines for VR and AR headsets. Examples include calibration, performance tests, and examining software content. In addition to image quality factors such as sharpness or color fidelity, the tracking systems also find problems such as deviations.

The manufacturer provides information on all VR headsets compatible with the testing system. Optofidelity also describes the setup as relatively uncomplicated. All the necessary components are included. Buddy, therefore, replaces even complex laboratory setups, according to the promotional material.

An important metric is the motion-to-photon latency. It measures the delay between a head movement and its visible implementation in the virtual world. If the latency is too high, the backdrop moves too late, which can cause nausea or a weaker sense of presence.

How stably objects remain anchored in the world or in front of the head can also be checked. Thanks to a novel synchronization technique, modern and future screen technologies should also remain measurable. These include OLED, light field displays, and projection-based screens.

Data sheets on the official website largely focused on previous iterations of the Buddy system with three degrees of freedom (3DOF). This restricted version only moves on a fixed base, instead of also sliding sideways on a rail across the floor.

The motion-to-photo analysis described can be performed here at a frame rate of up to 120 hertz. Simulatable pupil distances range from 55 to 75 millimeters, which also imitates very narrow and wide eye distances.

The official Optofidelity Buddy website lists further technical details, including the Robotics Specifications for fine details such as movement speeds or possible deviations. There, the 3DOF variant can also be examined during a test run with Hololens. Optofidelity provides prices for the Buddy systems on request.
