Faster Command Selection on Touchscreen Watches
summary
Two techniques are implemented for tiny watch screens: WristTap uses multitouch to select in a single action, TwoTap uses two rapid sequential taps. Performance studies with 14–20 participants use 2x2–4x4 grids and overloaded three 3x3 menus. Fast users reach ~1.0 second selections, supporting up to 18 commands with a 3x3 grid design; WristTap is slightly faster but has higher selection errors, TwoTap yields fewer selection errors but more recoverable category errors, overall error rates around 3% or lower.
