Touch input refers to the method of interacting with electronic devices by physically touching the screen or surface. This technology is commonly found in devices like smartphones, tablets, and touch-enabled laptops. Users can perform various actions, such as tapping, swiping, or pinching, to navigate applications and access features. The underlying technology for touch input often involves capacitive or resistive touchscreens. Capacitive screens detect touch through electrical signals, while resistive screens respond to pressure. Both types allow for intuitive user experiences, making it easier for people to engage with digital content without the need for a keyboard or mouse.
