Systems and methods for generating friction and vibrotactile effects
First Claim
1. A system for reducing adaptation to a haptic effect, the system comprising:
- a sensor configured to sense an input received at a surface;
a first haptic output device configured to generate a first type of haptic feedback;
a second haptic output device configured to generate a second type of haptic feedback that is different than the first type of haptic feedback;
a processor in communication with the sensor, the first haptic output device, and the second haptic output device; and
a memory on which instructions executable by the processor are stored to cause the processor to;
determine that the haptic effect is to be output for a duration in response to the input, the haptic effect being the first type of haptic feedback;
cause the first haptic output device to output the haptic effect for a time period that is less than the duration; and
in response to the time period exceeding a predetermined amount of time associated with adapting to the haptic effect, cause the second haptic output device to output the second type of haptic feedback during the duration.

Abstract
A system includes a sensor configured to sense an input received from a user at a surface; a first haptic output device configured to generate a first haptic effect at the surface based on the input received from the user, the first haptic effect comprising a friction effect at the surface; a second haptic output device configured to generate a second haptic effect, the second haptic effect comprising vibrotactile feedback; and a processor configured to receive an input signal from the sensor and output a first drive signal to the first haptic output device to generate the first haptic effect and to output a second drive signal to the second haptic output device to generate the second haptic effect.

23. A method for reducing adaptation to a haptic effect, the method comprising:
-
determining that the haptic effect is to be output for a duration in response to an input, the haptic effect being a first type of haptic feedback; causing a first haptic output device to output the haptic effect for a time period that is less than the duration; and in response to the time period exceeding a predetermined amount of time associated with adapting to the haptic effect, causing a second haptic output device to output a second type of haptic feedback during the duration, the second type of haptic feedback being different from the first type of haptic feedback. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
