Apple Vision Pro starts at $3499 next year

[Sterling Crispin 🕊️ @sterlingcrispin]

I spent 10% of my life contributing to the development of the #VisionPro while I worked at Apple as a Neurotechnology Prototyping Researcher in the Technology Development Group. It’s the longest I’ve ever worked on a single effort. I’m proud and relieved that it’s finally announced. I’ve been working on AR and VR for ten years, and in many ways, this is a culmination of the whole industry into a single product. I’m thankful I helped make it real, and I’m open to consulting and taking calls if you’re looking to enter the space or refine your strategy.

The work I did supported the foundational development of Vision Pro, the mindfulness experiences, ▇▇▇▇▇▇ products, and also more ambitious moonshot research with neurotechnology. Like, predicting you’ll click on something before you do, basically mind reading. I was there for 3.5 years and left at the end of 2021, so I’m excited to experience how the last two years brought everything together. I’m really curious what made the cut and what will be released later on.

Specifically, I’m proud of contributing to the initial vision, strategy and direction of the ▇▇▇▇▇▇ program for Vision Pro. The work I did on a small team helped green light that product category, and I think it could have significant global impact one day.

The large majority of work I did at Apple is under NDA, and was spread across a wide range of topics and approaches. But a few things have become public through patents which I can cite and paraphrase below.

Generally as a whole, a lot of the work I did involved detecting the mental state of users based on data from their body and brain when they were in immersive experiences.

So, a user is in a mixed reality or virtual reality experience, and AI models are trying to predict if you are feeling curious, mind wandering, scared, paying attention, remembering a past experience, or some other cognitive state. And these may be inferred through measurements like eye tracking, electrical activity in the brain, heart beats and rhythms, muscle activity, blood density in the brain, blood pressure, skin conductance etc.

There were a lot of tricks involved to make specific predictions possible, which the handful of patents I’m named on go into detail about. One of the coolest results involved predicting a user was going to click on something before they actually did. That was a ton of work and something I’m proud of. Your pupil reacts before you click in part because you expect something will happen after you click. So you can create biofeedback with a user's brain by monitoring their eye behavior, and redesigning the UI in real time to create more of this anticipatory pupil response. It’s a crude brain computer interface via the eyes, but very cool. And I’d take that over invasive brain surgery any day.

Other tricks to infer cognitive state involved quickly flashing visuals or sounds to a user in ways they may not perceive, and then measuring their reaction to it.

Another patent goes into details about using machine learning and signals from the body and brain to predict how focused, or relaxed you are, or how well you are learning. And then updating virtual environments to enhance those states. So, imagine an adaptive immersive environment that helps you learn, or work, or relax by changing what you’re seeing and hearing in the background.

All of these details are publicly available in patents, and were carefully written to not leak anything. There was a ton of other stuff I was involved with, and hopefully more of it will see the light of day eventually.

A lot of people have waited a long time for this product. But it’s still one step forward on the road to VR. And it’s going to take until the end of this decade for the industry to fully catch up to the grand vision for this tech.

Again, I’m open to consulting work and taking calls if your business is looking to enter the space or refine your strategy. Mostly, I’m proud and relieved this has finally been announced. It’s been over five years since I started working on this, and I spent a significant portion of my life on it, as did an army of other designers and engineers. I hope the whole is greater than the sum of the parts and Vision Pro blows your mind.

Wow! So the Quest 2 can actually pull off full body tracking without the need of any extra trackers. Very impressive and exciting news for social apps like VRChat.

Very impressive how quickly it builds a 3D map of my house. 👏 @Apple

Thanks to the "The Physical Tracked Keyboard SDK" you can use a compatible keyboard as an "Image Marker" to (re)align or sync a Unity scene with one or many players.

I turned my apartment into a VR game platform since I #WFH Thanks to @Oculus Quest & @unity3d. If you have to be locked in your home all day, might as well make it fun!
Available soon on @SideQuestVR for you guys, to try out my experimentations with tangible UI #MadeWithUnity

What a strange feeling when you remove your headset and your brain makes you think that you're still wearing it.
I decided to release pretty soon a POC on #SideQuest for any creator who would like to try the alignment system instead of a video. Sorry for the delay @iBrews😅

[Devolver Digital @devolverdigital]

Heave Ho from @LeCartelStudio is a deliriously funny local multiplayer adventure across an impossibly wide ravine!

Coming to Nintendo Switch and Steam this summer, playable on a massive 4K LED wall at PAX East all weekend!

Bonjour @SamsungFR , j'ai profité de votre offre de reprise et votre partenaire @Evollis_Leasing effectue une décote pour micro rayures afficheur et face arrière sur mon S7 Edge alors que celui-ci était entièrement protégé, avez-vous une solution ?

[Quentin Guay @Razishder]

@Mr_chuxxx @kh_ux_na Hi, I'm interested, MP ?

[fail0verflow @fail0verflow]

Code execution is all the rage these days, but can your Switch do *this*? ;-) #switchnix

[Quentin Guay @Razishder]

@ValTalonheart Hello, I'm in the opposite situation : looking for a code and using an Android device. If that's ok for you I could exchange it for a steam key (I can DM it to you) ?
