A touchless interface is a technology that allows users to interact with devices without physical contact. This can be achieved through various methods, such as gesture recognition, voice commands, or eye tracking. Touchless interfaces are commonly used in smartphones, smart home devices, and public kiosks, enhancing convenience and hygiene. These interfaces are particularly beneficial in environments where cleanliness is crucial, such as hospitals and kitchens. By eliminating the need for touching screens or buttons, touchless technology reduces the spread of germs and makes it easier for users to operate devices while multitasking or wearing gloves.
