Touch feedback refers to the sensory response that users receive when interacting with a device's touchscreen. This feedback can come in various forms, such as vibrations or subtle movements, which help users understand that their touch has been registered. It enhances the overall user experience by providing a sense of confirmation and improving the interaction with digital interfaces. In modern devices like smartphones and tablets, touch feedback is often integrated into the operating system, allowing for a more intuitive experience. This technology is crucial for applications in gaming, navigation, and typing, as it helps users feel more connected to their actions on the screen, making interactions more engaging and effective.
