Force feedback

Definition

Force feedback is a technology that provides tactile sensations to the user, simulating the feeling of physical interaction with virtual objects or environments. This is achieved by using sensors and actuators to apply forces or vibrations, allowing users to perceive and manipulate digital elements as if they were real. By enhancing the realism of virtual interactions, force feedback plays a crucial role in applications such as surgical simulation and rehabilitation technologies.
