Haptic feedback interface

Definition

A haptic feedback interface is a technology that provides tactile sensations to users through touch, enhancing the interaction with virtual environments or remote systems. This interface utilizes forces, vibrations, or motions to simulate the sense of touch, allowing users to feel and manipulate objects in a digital or robotic context. By integrating haptic feedback into teleoperation interfaces, it enhances the operator's ability to control devices and provides critical sensory information that can improve precision and effectiveness during tasks.
