Touchless interfaces are systems that allow users to interact with devices without physical contact. These interfaces often use technologies like gesture recognition, voice commands, or eye tracking to interpret user actions. This can enhance convenience and hygiene, especially in public spaces or during tasks where hands may be dirty. Common examples of touchless interfaces include smart home devices that respond to voice commands and gesture-controlled gaming systems that track body movements. As technology advances, touchless interfaces are becoming more prevalent in various fields, including healthcare, automotive, and smart appliances, making interactions more intuitive and efficient.
