The Impact of Low Vision on Touch-Gesture Articulation on Mobile Devices

A comprehensive study of stroke gestures on mobile device touchscreens by users with low vision reveals that some aspects of gesture articulation, such as gesture length or size, are minimally impacted by the impairment, while other aspects, such as production times, reveal suboptimal visuomotor routines of eye-hand coordination. Informed by the studys findings, the authors outline design guidelines for effective stroke-gesture input on mobile devices under low vision conditions.
