Could this be used to create an “Air Keyboard” that allows you to type by pretending to type into the air?
A wrist worn device pr hand that can track individual fingers. Thus freeing up the hand to still do grasping and such.
1. the screens were mounted upright. Notice how keyboard are nearly flat by comparison.
2. touchscreens thus far can't tell a finger resting from a finger pressing. So while a near flat screen avoids much of the gorilla arm issue, longer durations will put strain on the wrists.
OTOH, if it is precise enough, you might be able to make a virtual chorded keyboard / keyer [0] with it using finger-on-finger or finger-on-hand gestures.
