Honest question, is it much different than how VR headsets track hand movements and gesture in VR?

From the reviews, it seems different and worse.

But it is something novel that requires serious research. Even if the result is disappointing, it is novel enough to not make the it a “scam using old te vc projection”. That was the point of my rhetorical question before.

Does it require serious research? I am not trying to be difficult but I have seen write ups on basic hand gesture tracking from 5+ years ago.

Depends how you define “serious”.

I am defining “serious for a consumer product company”. Putting that in a small device seems quite a feat.

If you define “serious” as “particles colliding” or “drugs that cure some type of cancer”, then no.

Keep in mind that I am using “serious” as opposed to “scammy”. I thin this pin is far from a scam.

Thats fair. I guess I am biased with one of the initial story that described the genesis of the product during a cliff top retreat on Benioff's property. All the hype, the demonstrations, but the actual product falls flat of any real functionality. There is a disconnect between the hype they sold and what they released. That is scam territory.

I remember my buddy casually controlling the volume in his car by rotating the index finger cw/ccw with his hand on a gearbox handle. It was round 6-7 years ago. Nothing projected on his hand though, as it was all projected on a windshield, only visible to him. BMW 7, iirc.

hand is just a surface bro, I don't think it has anything to do with hand, light will bounce back on any opaque surface, just think of it as a mini projector and it's not even full RGB spectrum colour.

The hand movement controls what is being showed in the projector, which are inputs of the computation it does.

You speak with such confidence. Always a reliable red flag that you don’t know what you are talking about.
