From mine certainly. Funny how fast we forget about tech that was for years pretty common and then completely disappeared as it turned out be be a fad.

> completely disappeared Became iPhone FaceID.

The Kinect v1 sensor did. The Kinect v2 used different tech. But as a control it disappeared.

Why is this just now news? They already built a similar device for their Project Orion glasses. As far as I can tell, this is just the same thing but with a PC driver.

Having tried prototypes at neuroscience conferences where their team attended, I can tell you that the device was incredibly brittle (e.g. damp wrist, interference from even the metal table or a nearby computer). As it says in the article, the device seems to be more robust, and ready for the market soon. After having used ML to tune the decoding model on many participants contributing EMG data.

Having tried prototypes of similar ideas since the 90s it seems like something wipes our memory of gorilla arm once a decade.

Very little info about its capability. How many distinct gestures does it have? Is it sophisticated enough to allow typing?

None of that is announced yet, but there are two open source datasets for gestures and typing:

Infer what you will.

(I helped with their release and last month gave a presentation on the project's original research infrastructure, but I'm no longer on the team and I definitely never was allowed to talk about final products.)

Why gorilla arm? This doesn't necessarily require lifting it. There's an old video around with Zuck doing gestures while walking and he starts with his arm mostly at rest. Even in the worst case, how is it more tiring than a phone?

I would say such inventions are as old as 30 years when i first heard of startups / inventors trying to do such stuff. Obviously the tech must be now much more mature. Still, it never got off back then because typing was magnitudes faster than what ever you could do with your hands alone. Learning to do such hand motions had a similiar fate as why alt keyboard layouts always stayed niche - most people have no patienc…

Heck, I’m just excited to potentially have more meta keys.

Gorilla arm is caused by briefly pointing at things in front of you in a repetitive manner. The problem is that this is such an easy to code, universal gesture that it creeps into every interface.
