Zero-Touch Interaction

An interaction paradigm that allows users to control devices or systems without physically touching them, typically through voice commands, gestures detected by cameras or sensors, or ambient sensing. Zero-touch interaction is particularly important for accessibility in contexts where users cannot or should not use their hands, such as when cooking with dirty hands, during medical procedures, or when motor impairments prevent precise touch input. This approach reduces reliance on touchscreens and physical controls that may present barriers for people with various disabilities.
