A user interface that relies on gestures and touches is termed a touch interface. Such interfaces allow users to interact directly with devices like smartphones, tablets, and touchscreen computers. By using gestures such as tapping, swiping, and pinching, users can navigate applications and access various functionalities without the need for traditional input devices like a mouse or keyboard. This intuitive method of interaction has become prevalent due to the increasing reliance on mobile devices and the push for more accessible technology.
