Force Feedback

A type of haptic technology that applies physical forces to the user through a device such as a stylus, joystick, or glove, simulating the sensation of touching or interacting with virtual objects. Unlike vibrotactile feedback which only provides vibrations, force feedback can push, pull, and resist movement, enabling users to feel the shape, texture, and boundaries of virtual objects in two or three dimensions. In accessibility contexts, force feedback devices allow people who are blind or have low vision to explore spatial content such as graphs, 3D models, maps, and scientific diagrams through touch, conveying geometric and structural information that audio or text descriptions alone cannot communicate.
