What do you mean by "monitoring muscle contraction events only"? Not trying to argue with you, just understanding how the technology is being perceived.
If I hold your fist/fingers and you try to make gestures, how do you expect the device to behave? I.e., if you think of a movement and signal that intention, but are not capable of carrying that through, because of someone else's hand, a mug, etc.
- bbor 2y agoInteresting question! I would guess that electrical signals to contract muscles occur IFF the muscles exert some force, regardless of whether the muscles are actually able to overcome other forces and physically contract. So I would guess that it would work as if no one was holding my hand. I'm guessing this naive understanding is off the mark, from the phrasing of your question?
- the-rc 2y agoI was trying to figure if by "contraction events" you meant the actual motion or the signal to initiate that. Maybe it was the former, but it looks like you meant the latter. The wristband's EMG sensors can't detect the motion of the fingers themselves, of course, because it's on the wrist (and the signal passes through that before the relatively slow muscles have had time to act upon it). There are videos of people able to control virtual hands even with partial or missing fingers, be that since birth or after some event, see e.g. https://www.youtube.com/watch?v=woXmJMw2lTM&t=4717s https://www.youtube.com/watch?v=woXmJMw2lTM&t=4717s
