Touch interaction refers to the way users engage with devices through physical contact, typically using their fingers. This method is common in devices like smartphones and tablets, where users can tap, swipe, or pinch to navigate and control applications. Touch interaction enhances user experience by providing intuitive and direct manipulation of digital content. The technology behind touch interaction often involves capacitive or resistive touchscreens. Capacitive screens detect the electrical properties of the human body, while resistive screens respond to pressure. Both types enable users to interact seamlessly with software, making tasks like browsing the internet or playing games more accessible and enjoyable.
