Connected ambulance crews debut mixed-reality emergency response
By Paul Ridden
December 18, 2023
An ambulance service in Sri Lanka has equipped its EMTs with a mixed-reality headset to help deliver emergency care with the help of a live-feed doctor in the crucial moments before a patient is admitted to hospital.

Singapore-based digital healthcare startup Mediwave, part of Wavenet Telecomms, has rolled out its Emergency Response Suite to Emergency Response Technicians working for Sri Lankan pre-hospital ambulance service 1990 Suwa Seriya, delivering what's claimed to be the "world's first mixed-reality and AI-powered connected ambulance."

When a medical emergency is logged at a 1990 Command and Control Center, the EMT sent out in the connected ambulance could be wearing a Microsoft HoloLens mixed-reality headset. This will see the technician poking wildly in the air to access menus and systems out front of the wearer, but invisible to onlookers.

A skin-integrated multimodal haptic interface to produce immersive tactile experiences
https://techxplore.com/news/2023-12-ski ... rsive.html
by Ingrid Fadelli , Tech Xplore

Virtual reality (VR) and augmented reality (AR) technologies have become increasingly advanced over the past decade or so, enabling highly engaging gaming experiences and new forms of media entertainment. Yet there is still significant room to improvement, particularly in terms of artificially stimulating other senses beyond vision and hearing.

Researchers at City University of Hong Kong and other institutes in China have been trying to develop new interfaces that would allow end-users to closely connect with virtual environments through their sense of touch. In a recent paper, published in Nature Electronics, they introduced a new haptic interface that delivers multi-dimensional tactile signals directly on the skin, eliciting realistic sensations that could further enhance virtual experiences.

"Currently, global research on flexible electronics primarily focuses on the development of flexible sensors, while the investigation into flexible feedback techniques remains limited," Ya Huang, co-author of the paper, told Tech Xplore.

miniaturisation and efficiency

Post by Tadasuke »

If we would try to put 1000 watts PC specs (let's say overclocked Ryzen 7950X3D + two RTX 4090) into a 1 watt standalone VR headset, we could need even up to 1000x better energy efficiency, which could possibly take 30 or even up to 40 years, without achieving any better performance than achievable today. Unless, there is some huge situation-altering breakthrough.

So perhaps we will need to stick to some not particularly impressive specs, like perhaps something akin to PlayStation 5 or so in the foreseeable future, which btw wouldn't be far from what John Carmack was predicting. PS5 = 220 watts, PS5 Slim = 180 watts. Going down to 1 watt is still a long way and we are discussing only current PS5 level, nothing above that. I remind you, that Apple Vision Pro is going to last only 2 hours on its internal battery and Steam Deck OLED lasts 2.5-3.5 hours when not on full brightness.

Much better batteries and/or cooling would help. There are some solutions coming later this year, which could improve those (Frore Systems AirJet and lithium–sulfur batteries).

ARM architectures aren't as good in actual useful workloads as in some benchmarks. Quest 3 is possibly (I'm guessing) similarly fast as a PC with Ryzen 1600 running at 3 GHz and Radeon HD 6870 (Quest 2 like i5-2500 at 3 GHz and Radeon HD 5750). Though, I don't even know where to look for actual performance results.

Zeiss Smart Glass tech could place a transparent camera mid-window
By Paul Ridden
January 05, 2024
German optics titan Zeiss is heading to CES next week to show off its Multifunctional Smart Glass technology, which can float "holographic" and augmented-reality content on a transparent surface for such things as head-up displays in cars, 3D control elements in smart homes, and even a transparent videocam in the middle of a glass panel.

Zeiss first announced the development in early 2019, and it had matured enough by last year for use in augmented-reality head-up displays (HUD) in aircraft cockpits. The company revealed plans to move into automotive applications at IAA Mobility 2023, and is now pushing for mass production in what VP Roman Kleindienst is calling a "Gutenberg moment for holography."

The technology is built around a thin polymer film that can "turn any glass surface (windows of buildings, transparent screens, side windows of vehicles) into an on-demand screen for communications." The company says that the film offers more than 92 percent transparency, features "ultra-high-precision optics," and combines projection, detection, illumination and filtering functionality.

Apple Might Have Sold 180,000 Vision Pro Headsets Already
It's a better-than-expected result for the $3,500 product.
By Josh Norem January 22, 2024
https://www.extremetech.com/electronics ... ts-already
Apple's highly anticipated Vision Pro headset went up for pre-order last week, and according to a new report, it might have exceeded Apple's expectations. One reliable Apple analyst suggests the company sold up to 180,000 units, so it saw around $630 million deposited into its bank account over the weekend. Despite apparent initial interest in the spendy headset, the future of the device is hardly set in stone, as it has a long road ahead if it wants to become the company's next must-have device.

Famed Apple analyst Min-Chi Kuo has posted a report analyzing how many Vision Pro headsets Apple has sold so far. His math appears to be partly based on pre-order shipping times, which will increase as units become sold out. As Engadget notes, Kuo initially estimated Apple would only produce 60,000 to 80,000 units, making it an extremely niche product for the company. His latest estimate states it sold between 160,000 to 180,000 units, meaning demand far exceeded supply, leading to immediate shipping delays for the device, with a starting price of $3,500.

Phantom VR glove delivers a sense of touch, but leaves fingers free
By Ben Coxworth
January 29, 2024
There are now a number of high-tech gloves that deliver tactile sensations to VR users' fingertips when they touch virtual objects or surfaces. The Phantom glove is unique, however, in that it doesn't cover the fingers, leaving them free for real-world interactions.

Developed by Colorado-based VR startup Afference, the Phantom is the recipient of a CES 2024 Innovation Award.

The wearable device incorporates an electronics/battery module which is hard-wired to five adjustable-size rings fastened around the base of each finger. All of these components are connected to a lightweight fabric harness that is fastened around the wrist, and which does not cover the palm of the hand.

Tesla owners told not to wear Apple virtual reality headsets while driving

3 hours ago

Tesla owners have been reminded to keep their eyes on the road after videos of drivers wearing Apple's virtual reality headset have gone viral.

US Secretary for Transport Pete Buttigieg posted on X (formerly Twitter) to say that all current vehicles require the driver to be engaged "at all times".

However, one driver admitted his video was a prank.

Tesla and Apple have been contacted for comment.

Videos posted online show people in the drivers seats of cars which have an autonomous mode, while wearing the Apple headset over their eyes.

From the article:
Just last December, six years after he told Venture Beat that such devices were five to seven years away, Tim Sweeney told Alex Heath, “Well, I think that augmented reality is the platform of the future. But it’s very clear from the efforts of Magic Leap and others that we need not just new technology but, to some extent, new science in order to build an augmented reality platform that’s a substitute for smartphones. And it’s not clear to me whether that’s coming in 10 years or in 30 years. I hope we’ll see it in my lifetime, but I’m actually not sure about that.”
Arguably a new technology is creating that new science - the advancements in AI is paving the way for and already creating new advancements in science. AI has simulated and tested in those simulations all kinds of new designs and new metamaterials with unique properties.We maybe be years away from AGI, but narrow AI may be enough to usher in a new age of progress and innovation all by itself. It takes time and scale to create these new designs and materials AI has come up with and in abundance to be useful and implemented in devices, but just the fact that the mere knowledge the "knowing it can exist and is possible and this is how to do it" is now in our possession has shaved years and perhaps decades away from the process. True they don't exist in our hands now and won't for a few years yet at least, but it's accelerated things from "not in our lifetimes" to "maybe with this decade or maybe within a few decades." In our always "now" perception of time it might not feel like the future has gotten any closer but it indeed has.

All this to say, there's starting to slowly be room for optimism. True, the future isn't here yet, and it's still feeling a lot like the perpetual "it's just a few years away" mindset of the past 20 years, but that perpetual bit might not remain perpetual for very much longer. It might not be a few years away yet, but we're getting to the point where in a few years when the experts repeat the age old mantra of "a few years away" it might actually for the first time ever really just be a few years away from then. I think that's the promise of current AI some of us are missing, the timeline is actually shortening.

Apple Vision Pro is about to enable fully immersive 3D music production
By Paul Ridden
February 21, 2024
https://newatlas.com/music/hitnmix-ripx ... ision-pro/
Producing music these days can be something of a flat experience, undertaken using powerful software running on a computer. With the sales launch of the Apple Vision Pro, DAW maker Hit'n'Mix is planning to immerse musicians in their creations.

Apple wasn't first to the mobile music game, but the iPod supercharged the market. Likewise with smartphones and tablets. With players like Meta and HTC already well established in the VR/AR headset space, Apple finally revealed its challenger in June of last year in the shape of the US$3,499 Vision Pro "spatial computer."

It only actually went on sale earlier this month though, and launched with hundreds of apps to immerse users in digitally augmented or virtual worlds – but there were a few notable omissions, including Netflix and YouTube. Reviews from users and tech mags have been mostly positive – though Mark Zuckerberg cheekily took to Insta last week with an unsurprising recommendation for folks to use the latest Quest instead.

Lenovo Unveils 'Augmented Reality' Laptop With a Transparent Display
It definitely looks cool, but use cases are few and far between, for now.
By Josh Norem February 26, 2024

Two weeks ago, a rumor circulated that Lenovo was about to introduce a laptop with a transparent display. We thought it sounded like a cool gimmick at the time, but we'd wait and see what Lenovo has in store for us. Today, at the Mobile World Congress (MWC) trade show in Barcelona, the company officially pulled the wraps off it, and our thoughts have not changed. It looks wicked cool, but it's hard to imagine anyone using one in the real world soon. Still, it's a novel concept, and perhaps it'll be useful 10 years from now.

It doesn't seem like adoption of new tech is being faster than let's say smartphone (or tablet) adoption in the past. Perhaps, adoption of Large Language Models or Text-To-Image "AIs" is quicker (not for me). But I meant tech as physical stuff, not computer code. We don't live in computers (as of today at least).

There are some new things and more things, but it certainly doesn't feel like we are approaching some "tech singularity" event or period. Just more and slightly better things <--- that's pretty much it.

VR could enable us to live our lives in realities with different rules, situations and bodies we choose for ourselves, instead of being cruelly forced to "just accept and adapt".

AR could enable us to live better (or worse) lives in this reality (with acceptance and adaptation becoming easier and more fun). Depends how it will be used. It will surely lead to some accidents and addictions for some individuals, could be even worse than smartphones in that regard.

I don't see any major "revolutions" in areas of VR, AR and MR in the next few years. At least PS VR 2 is coming to PC.

Surgical Teams Are Using the Apple Vision Pro to Double-Check Their Work
Apple's augmented reality headset helps medical professionals map out and cross-reference hands-on procedures.
By Adrianna Nine March 13, 2024
If you're in the pre-op room and you see a nurse strapping on a Vision Pro right before the anesthesia hits, don't freak out. Medical professionals are beginning to test the viability of Apple's augmented reality headset as a cross-reference tool for hands-on work. According to a few surgeons and operating room (OR) nurses who have worn the Vision Pro in the surgical suite, the goggles might help eliminate the sliver of human error within every medical procedure.

The Vision Pro's compatibility with real-life surgery is all thanks to eXeX (short for eXpanded eXistence Inc.), a Florida-based mixed-reality startup. One of eXeX's three core products, ViewerX, typically allows surgical teams to organize and track procedures on an iPad. Now ExperienceX, the company's AR-oriented version of the software, puts the display in the nurse's or surgeon's view. The eXeX website claims this improves organization and a higher "flow state" during surgery.

The new tech bringing loved ones back to life through AI
Friday 29 March 2024 09:55, UK

Image

When technology entrepreneur Artur Sychov's father was diagnosed with cancer, he was forced to accept a day may soon come when he wouldn't be able to speak to him again.

The 38-year-old knew he would give anything to have another father-son conversation after his dad's death.

So, using artificial intelligence, he got to work on a way that could make it happen for others in his position.

Artur has created a virtual reality tool called "live forever mode". It features digital avatars who can simulate a person's voice, mannerisms and movements after just 30 minutes of the user being observed.

The goal is for the avatar to live forever online as a memory of its creator so future generations of their family can interact with it.
