Abstract
Systems and methods for perceptual normalization of haptic effects are disclosed. One system may include a first sensor configured to detect a user interaction with a touch surface and transmit a first sensor signal associated with the user interaction; a second sensor configured to detect a feature associated with the touch surface and transmit a second sensor signal associated with the feature; a processor in communication with the first sensor and the second sensor, the processor configured to: determine a first haptic effect based on the user interaction; determine a modified haptic effect based in part first haptic effect and on the feature; output a haptic signal associated with the modified haptic effect; and a haptic output device in communication with the processor and coupled to the touch surface, the haptic output device configured to receive the haptic signal and output the modified haptic effect to the touch surface.
