Abstract:
Systems and methods for multi-level closed loop control of haptic effects are disclosed. One illustrative system for multi-level closed loop control of haptic effects includes a haptic output device configured to output a haptic effect, a sensor configured to sense the output of the haptic output device and generate a sensor signal, and a processor in communication with the sensor. The processor is configured to: receive a reference signal, receive the sensor signal, determine an error based at least in part on the reference signal and the sensor signal, generate a haptic signal based at least in part on the reference signal and the error, and transmit the haptic signal to a haptic output device configured to output a haptic effect based on the haptic signal.
