AI? VR? The term might just refer to whatever Meta is doing now.

Almost two years ago, Mark Zuckerberg rebranded his company Facebook to Meta — and since then, he has been focused on building the “metaverse,” a three-dimensional virtual reality. But the metaverse has lost some of its luster since 2021. Companies like Disney have closed down their metaverse divisions and deemphasized using the word, while crypto-based startup metaverses have quietly languished or imploded. In 2022, Meta’s Reality Labs division reported an operational loss of $13.7 billion.

But at Meta Connect 2023, Zuckerberg still hasn’t given up on the metaverse — he’s just shifted how he talks about it. He once focused on… More.

Meta launches Quest 3 and continues to focus on the metaverse — even though the market isn’t as positive. Zuckerberg shows a shift in his thinking about the concept.

YouTuber Lucas VRTech has designed and built a pair of finger-tracking VR gloves using just $22 in materials — and he’s released all the details on the build so others can make their own.

The challenge: We use our hands to manipulate objects in the real world, but in VR, users typically have to use controllers with buttons and joysticks.

That breaks some of the immersion, limiting the use of VR for not only gaming, but also applications like therapy and job training.

Pediatric specialists at Lucile Packard Children’s Hospital Stanford are implementing innovative uses for immersive virtual reality (VR) and augmented reality (AR) technologies to advance patient care and improve the patient experience.

Through the hospital’s CHARIOT program, Packard Children’s is one of the only hospitals in the world to have VR available on every unit to help engage and distract patients undergoing a range of hospital procedures. Within the Betty Irene Moore Children’s Heart Center, three unique VR projects are influencing medical education for congenital heart defects, preparing patients for procedures and aiding surgeons in the operating room. And for patients and providers looking to learn more about some of the therapies offered within our Fetal and Pregnancy Health Program, a new VR simulation helps them understand the treatments at a much closer level.

Please attend our Virtual Realilty Ending Aging Forum!

This event will showcase the newest breakthroughs in rejuvenation biotechnologies happening at the SENS Research Foundation’s Research Center in Mountain View, CA, as well as the research funded at extramural labs.

The Forum will be hosted virtually through Meetaverse, a state-of-the-art Virtual Reality platform.

This virtual event is your opportunity to hear first-hand about the latest advances that our in-house researchers are making toward new rejuvenation biotechnologies, along with some of our young scientists-in-training and outside researchers whose research we fund.

Flat screen TVs that incorporate quantum dots are now commercially available, but it has been more difficult to create arrays of their elongated cousins, quantum rods, for commercial devices. Quantum rods can control both the polarization and color of light, to generate 3D images for virtual reality devices.

Using scaffolds made of folded DNA, MIT engineers have come up with a new way to precisely assemble arrays of quantum rods. By depositing quantum rods onto a DNA scaffold in a highly controlled way, the researchers can regulate their orientation, which is a key factor in determining the polarization of light emitted by the array. This makes it easier to add depth and dimensionality to a virtual scene.

“One of the challenges with quantum rods is: How do you align them all at the nanoscale so they’re all pointing in the same direction?” says Mark Bathe, an MIT professor of biological engineering and the senior author of the new study. “When they’re all pointing in the same direction on a 2D surface, then they all have the same properties of how they interact with light and control its polarization.”

This talk is about how you can use wireless signals and fuse them with vision and other sensing modalities through AI algorithms to give humans and robots X-ray vision to see objects hidden inside boxes or behind other object.

Tara Boroushaki is a Ph.D student at MIT. Her research focuses on fusing radio frequency (RF) sensing with vision through artificial intelligence. She designs algorithms and builds systems that leverage such fusion to enable capabilities that were not feasible before in applications spanning augmented reality, virtual reality, robotics, smart homes, and smart manufacturing. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Testing time: To see whether the modified VR headset could accurately record brain activity, the researchers had four participants wear it while opening or closing their eyes on command. There is typically an increase in alpha waves in a person’s brain when their eyes are closed, and the researchers could see this increase in the EEG data recorded by their headset.

They also had the participants wear the headset while playing a custom game designed to trigger a type of brain activity that occurs when a person is preparing for an event. As hoped, the researchers were able to see this activity in the recorded EEG data, too.

Looking ahead: The UT Austin team has started filing the paperwork to patent their tech and say they’d be open to working with VR companies to incorporate it into their systems. They don’t say what it costs to make the soft electrodes, so it’s not clear exactly how much consumers or professionals should expect to pay for a modified VR headset.

Apple reportedly has several teams working and spending millions on generative AI.

Apple is spending millions of dollars a day to build artificial intelligence tools, according to The Information.

Although Apple considers itself to be its closest competitor, given how it chose to launch Vision Pro when the clamor around AR/VR tech had died down, the scale of investments by Apple is telling of how the tech industry’s pivot to generative AI has affected the company’s outlook, especially with OpenAI’s chatbot ChatGPT taking center stage.

Apple is apparently going hard on developing AI, according to a new report that says it’s investing millions of dollars every day in multiple AI projects to rival the likes of ChatGPT.

Roblox’s new AI assistant is one of a few new AI tools from the company.

Roblox announced a new conversational AI assistant at its 2023 Roblox Developers Conference (RDC) that can help creators more easily make experiences for the popular social app. The new tool, the Roblox Assistant, builds on previously announced features that let creators build virtual assets and write code with the help of generative AI.

With the Roblox Assistant, creators will be able to type in prompts to do things like generate virtual environments. In one demo, somebody types in “I want to make a game set in ancient ruins,” and Roblox drops in some stones, moss-covered columns, and broken architecture. “Make the… More.

Another AI chatbot, but this seems useful.

Metalens for AR and VR.

BEIJING, Sept. 8, 2023 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, today announced that a metasurface eyepiece for augmented reality has been developed, which is based on metasurfaces composed of artificially fabricated subwavelength structures. The metasurface eyepiece employs a special optical design and engineered anisotropic optical response to achieve an ultra-wide field of view(FOV), full-color imaging, and high-resolution near-eye display.

At the heart of the WiMi’s metalens are see-through metalens with a high numerical aperture(NA), a large area and broadband characteristics. Its anisotropic optical response allows it to perform two different optical functions simultaneously. First, it can image virtual information, acting as an imaging lens for virtual information. Second, it can transmit light, serving as a transparent glass for viewing a real-world scene. This design allows the transparent metalens to be placed directly in front of the eye without the need for additional optics, resulting in a wider FOV.

Fabrication of metalens is done using nanoimprinting technology, which is capable of fabricating large-area metalens with sub-wavelength structures. First, a mould or template with the desired structure is prepared. Then, the mould or template is contacted with a transparent substrate and the nanoscale structure is transferred by applying pressure and temperature. Through this nanoimprinting process, the subwavelength structure of the metalens is successfully replicated onto the transparent substrate, resulting in the formation of the metalens.
