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.
