The images generated by the Tomo strap are low-resolution, but still provide enough detail for software to distinguish between a wide variety of hand and finger gestures being performed. And because the analysis is all being done internally, the system should work just as well in the dark, or even when the wearer has gloves on.


It’s not perfect yet, though. Differences in how the strap is worn from day to day can throw off the software’s ability to accurate detect gestures as defined on a previous day. And since everyone would be performing them differently, with varying physiologies between users, the Tomo system would have be taught to recognize the gestures first, which would make setting up a new smartwatch and even more agonizing procedure.
