Hands-Free Interface

A hands-free interface is a computer interaction system that does not require the use of hands or fingers, enabling users to control software through alternative input channels such as head movements, eye gaze, voice commands, foot pedals, or breath-controlled switches. These interfaces serve individuals with upper-limb motor disabilities, paralysis, or repetitive strain injuries, as well as people in hands-busy situations such as surgical procedures or mechanical work. Effective hands-free interfaces must replicate the full range of mouse and keyboard functionality, including pointing, clicking, text entry, and application-specific commands.
