Applications of Force-Feedback Interfaces for Gesture and Motion Assistance
Specifications and applications of force feedback interfaces: virtual reality and gesture and movement assistance

Force-feedback interfaces are unique in that they can “step back” to follow their users’ movements without offering resistance—thanks to their transparency and reversibility—or, conversely, assist these movements to help operators perform their work, thanks to their high force capacity and significant dynamics.

Thanks to these exceptional capabilities, they have numerous applications in fields where the goal is to provide assistance with the operator’s gestures or movements, with two main functionalities:

• force assistance, which reduces the physical strain of certain tasks by amplifying the forces and torques applied by the user;

• position assistance, which facilitates and ensures the safety of the operator’s...
