Use it to make head-mounted pointers? (Score 1)

About 6 years ago I tried mounting a gyro-mouse to a helmet to see if it would be suitable to give my arms a rest, since I suffer from a repetitive stress disorder in both arms. (A gyro mouse is a hand-held mouse that you wave in the air to move the cursor rather than moving it across a flat surface).

It was futile, I quickly discovered, because my head (and everyone else's) has a subtle jittery motion that I didn't know about until I tried this experiment. It makes the cursor erratic.

Hands have much finer control, and doubly so when they're pushing a mouse across a stable surface. For that reason, the hand-held gyro mouse works pretty well, and standard surface mice work extremely well.

So now I wonder if this product (the motion smoothing aspect of it) could be used to make a do-it-yourself head-mounted mouse.

I know there are already head-mounted products available, and at least some of them probably use similar algorithms, but last I checked--several years ago--the prices for quality head-tracking was quite high, and most of them used cameras or similar sensors to track wearable "dots" or your eyes.
