Abstract
Example systems and methods for closed-loop control for haptic feedback are disclosed. One example method includes the steps of outputting a first signal configured to cause a haptic output device to output a haptic effect to a surface; determining one or more first velocities of a surface of an object attracted towards the surface in response to the haptic effect; in response to the first velocities decreasing to approximately zero, discontinuing output of the first signal; determining one or more second velocities of a surface of an object rebounding away from the surface in response to the discontinuing output of the first signal; in response to the second velocities decreasing to approximately zero, determining a responsiveness of the surface of the object to the haptic effect; and outputting a second signal based on the responsiveness.
