Touch-Free Interaction

Interaction with digital systems without physically touching any device surface, achieved through gestures, voice, eye tracking, brain-computer interfaces, or proximity sensors. Touch-free interaction is important for accessibility because touchscreens present significant barriers for users who are blind (no visual reference for touch targets), have motor impairments (difficulty with precise touch), or have conditions affecting hand use. It also benefits situational accessibility, such as when hands are occupied or gloved.
