Which sounds amazing as long as you're willing to carry around the disembodied head of a tiny Transformer around when meddling with spreadsheets.

The team says that the reduced wrist angle lowers carpal tunnel, and it surely feels gentler than a bodily mouse: latency was respectable and the device demands a flat surface to operate, with the workable spot fixed at just above 3 inches squared.
Limitation-sensible, that spot cannot be modified and although laser projection is only in red, you will be ready to pick from 3 different colors of robotic shrunken heads.
