EMG is potentially capable of this and with adequate filtering techniques there are papers out there that allow for fairly accurate detection of finger motions. More so, the video shows use of very distinct hand positions. In other words, it is not the gesture but hand shape that can be read accurately and interpreted. I suspect it also has a gyro/accelerometer that works in tandem with multiple EMG sensing points…

Also looks like that video was entirely faked.  I see no evidence that any of that video footage was actually based on the sensor input.  It probably works decently, but I highly doubt it works as well as the video.

That looks like a lot of fun!

just cos there's no description, i'll add it here:  it's a muscle sensor that can be used for gestural control.
