MindMaze, a neurotechnology startup, is growing a easy, low-cost strategy to face-tracking known as MASK—claimed to be compatible with any VR headset—that may map considerably extra life-like expressions onto your virtual avatar.

I not too long ago met with MindMaze at their San Francisco working area to check Masks for myself and be taught extra about it.

Since optical, computer-vision based mostly face-tracking is made tougher in VR because of the headset blocking a good portion of the face, Masks as an alternative employs low-cost electrodes across the periphery of the headset’s foam padding to sense indicators generated if you transfer muscular tissues in your face.

Talking to MindMaze CEO Tej Tadi, I used to be instructed that the embedded sensing hardware may be very low-cost and provides little to the headset’s total price of producing. The problem will not be the hardware, Tadi says, however the software which is tasked with deciphering the input.

The electrodes, which make direct contact along with your face via the headset’s foam interface, only measure electrical amplitude. With eight electrodes embedded on the prototype model of the Masks that I attempted, the only factor the computer “sees” is eight incoming information streams that go up or down on a graph. Tadi says that MindMaze has utilized their neurotech data to create an algorithm that may learn that information, and, from it, extract a set of facial expressions.

Neuro-bamboozling vs. the Actual Deal

Now I ought to be clear up entrance that I’m extraordinarily skeptical in the case of neuro-bamboozling: that’s when firms use ‘neuroscience’, ‘neurotechnology’, and different mind buzzwords to make it look like they’re doing one thing extra vital than they are surely. One oft-seen instance of neuro-bamboozling is when an organization would possibly inform you one thing like, “you’ll be able to fly a drone along with your thoughts!,” which, 99% of the time, means they’re going to slap some electrodes in your head and inform you to “concentrate”, which can make the drone go up, after which to “relax” which can make the drone go down. It’s extremely binary, and finally not very helpful.

Nearest I can inform for MindMaze—at the least for Masks, as I haven’t seen their different merchandise—they’re the actual deal. Once I strapped on the headset to attempt Masks for myself, even with none calibration, a spread of canned expressions that I made have been shortly mirrored on the face of an avatar that represented me within the virtual world. Once I smiled, it smiled. Once I frowned, it frowned. Once I winked, it winked. It was simply the best calibration-free tech that I’ve seen of this type.


I used to be instructed the prototype presently helps 10 totally different facial expressions. As a result of they’re canned poses, which implies Masks can only present approximations of your expressions; it gained’t be capable to seize the distinctive actions of the face that make you, you, nevertheless it does cowl the fundamentals.

Along with the 10 present expressions, the staff says they’re working to suss much more expressions out of the info, together with the potential for rudimentary eye-tracking, which wouldn’t be exact sufficient for issues like foveated rendering however may very well be ok for expression mapping.
