Touch input refers to the method of interacting with electronic devices by physically touching the screen or surface. This technology is commonly used 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 touchscreens detect the electrical properties of the human finger, while resistive touchscreens respond to pressure. Both types allow for intuitive user experiences, making it easier for people to engage with digital content.
