Haptic feedback

Definition

Haptic feedback refers to the use of tactile sensations to provide users with physical responses in interaction with a device or system. This technology enhances user experience by simulating the sense of touch, which is crucial in applications requiring precision and control, such as robotic surgery and virtual environments. By translating digital actions into physical sensations, haptic feedback improves communication between the user and the system, making interactions more intuitive and effective.
