Touchless interaction refers to technology that allows users to control devices without physical contact. This can be achieved through various methods, such as gesture recognition, voice commands, or eye tracking. These systems use sensors and cameras to detect movements or sounds, enabling a more hygienic and convenient way to interact with devices. This type of interaction is increasingly used in areas like smart homes, automotive systems, and public kiosks. By eliminating the need for buttons or touchscreens, touchless interaction enhances user experience and reduces the spread of germs, making it particularly valuable in public spaces and healthcare settings.
