[Feature Request] Hand to mouse

[drawnograph]

I have recently become unable to use a computer because of RSI.
I'm using Talon Voice and Vimium for typing and web-browsing, but mouse use via an Tobii 5 eye-tracker has proven inaccurate and difficult, head-tracking using e-viacam is a lot of head-waving across dual-monitors and gets achy quickly.

Handtracking could replace mouse-usage with pinch-to-click, perhaps pinch-hold for right-click and v-fingers up/down scroll without putting any pressure on the wrist.

Screen-coordinate calibration and camera placement can remove issues with the hand in the line-of-sight and be useful for people with access needs that make mouse-usage impossible.

Many people with RSI find ways for words via dictation (ie with Dragon) but mouse-input often requires holding something, which eventually aggravates the condition. I think this feature would help those with mouse-usage issues.
(Also, thanks for putting this together!)
