Simulation-driven force-feedback controllers for haptic interaction
Validation level: 4. Other peer-reviewed paper publication
This technique couples a real-time interactive simulation of a physical model to a force-feedback controller, so that the sensations experienced by the user when interacting with the controller feels like physically interacting with the object that is simulated. In the most sophisticated versions of this technique, a single simulation is used to generate all the sensory feedback (auditory, visual and haptic)

Storyboard of Functions
physical simulation-driven force-feedback controllers are one of the most immersive ways of interacting with a computer, because it engages the human sensorimotor system in a way that emulates real-world physical interactions. It is especially useful in areas where expressive gestures are essential, such as music performances or tele-operation.
Real-time interactive physical simulations are computationally expensive, and as of 2019 they still require a heavy setup. Coupling these simulations to force-feedback controllers is particularly challenging, because generating haptic feedback in real time imposes strong constraints in terms of latency, sampling time, dynamic range and gain.
