This study aimed to quantify differences in 7 touchscreen gestures. Eighteen participants performedindex finger tapping, sliding in 4 orthogonal directions, and index finger and thumb pinch and stretchgestures on a touchscreen tablet computer. We hypothesized that two finger gestures would requirelonger task completion time and greater finger joint excursions than sliding gestures using only the indexfinger. We measured task completion times and finger joint kinematics. Tapping showed the fastestaverage (±SD) task completion time, 567(190) ms, of all gestures (p < 0.001). Pinch had faster taskcompletion time, 765(277) ms, than all single-finger sliding gestures (p < 0.001). Stretch was faster tocomplete at 843(317) ms (p < 0.001) than all sliding gestures except slide right. Stretch demonstratedgreater mean index finger metacarpophalangeal flexion/extension joint excursions, 63(16), compared tosliding gestures, 34(10), and tapping, 27(13) (p < 0.01). Overall, two-finger gestures were faster tocomplete and showed greater joint excursions than single-finger sliding gestures.
