Gesture-Based Input

An input method that interprets finger or hand movements — such as swipes, taps, and drawn paths — as commands or text characters. For people with visual impairments, gesture-based input on touchscreens offers an alternative to traditional keyboard layouts that require targeting specific screen locations. Gesture-based methods can leverage existing knowledge systems like Braille patterns or create new visual alphabets, and their effectiveness depends on balancing factors like gesture complexity, audio feedback design, and error correction strategies.
