Steady Tapping

The ability to place a finger on a touchscreen target and hold it still long enough for the system to register a deliberate tap, as opposed to the unintentional movements caused by hand tremor. For users with motor impairments, maintaining a steady tap is a significant challenge because tremor causes the finger to move during contact, potentially activating adjacent targets or triggering unintended gestures like scrolling. Assistive techniques to support steady tapping include filtering out rapid unintentional movements, using click-on-lift activation, and expanding touch areas to provide a larger margin for error. Steady tapping requirements are a key reason why touchscreen accessibility is difficult for people with conditions such as Parkinson's disease, essential tremor, or Multiple Sclerosis.
