Around 10 years ago I wrote a Linux driver for the OCZ Nia, a super cheap EMG device. The Nia was actually a $10k medical device for paralyzed people to control computers with their face and tongue repurposed as a gaming input and sold for $120.

While I'm certain the technology has advanced, what surprises me most is how basic these finger reading devices seem. They're basically some electrodes on your skin near major nerve centers and a little bit of signal processing, like barely any signal processing.

It's about time this technology entered the mainstream. I was waiting for VR with occular/vagus nerve sensing for depth of field emulation but I guess hand sensors are the next best thing.

The implementation shown in the video strikes me very much as an accessibility feature (which is a fine thing). By comparison, pressing the stateful stop button on my exercise watch is quick and straightforward.

There was also the Myo armband by Thalmic Labs, later North, later a division of Google. Apparently it didn't work very well though.
