Abstract

Systems and methods for perceptual normalization of haptic effects are disclosed. One system 100 may include a first sensor 108 configured to detect a user interaction with a touch surface 116 and transmit a first sensor signal associated with the user interaction; a second sensor 110, 130 configured to detect a feature associated with the touch surface and transmit a second sensor signal associated with the feature; a processor 102 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 118 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.

Description

technical field [0001] The present invention relates generally to haptic feedback, and more particularly to systems and methods for perceptual normalization of haptic effects. Background technique [0002] Touch-enabled devices have become increasingly common. For example, mobile and other devices are equipped with touch-sensitive displays such that users can provide input by touching portions of the touch-sensitive display. As another example, a touch-enabled surface separate from the display may be used for input, such as a touchpad, mouse, or other device. Additionally, some touch-enabled devices utilize haptic effects, eg, haptic effects configured to simulate texture or friction on a touch surface. This type of haptic effect can be used to provide information to the user. Sometimes, however, other factors affect the user perception of these effects and thus need to be compensated for.
