Described are devices that provide thermal haptic feedback. A touchpad, touchscreen or other such device may receive an indication of an adjustment at a first portion of a touch user interface, and in response, determine a temperature setting based on the adjustment. Voltage supplied to a matrix of temperature actuating elements at the touch user interface may then automatically control the haptic temperature feedback. Color and brightness correction may be provided to account for the heat of the temperature actuating elements. Also, the thermal haptic feedback may be provided by a trackball. In response to an adjustment of a value of a parameter effected by the trackball, the medium may automatically control one or more temperature actuating elements in the trackball to provide a haptic temperature feedback.
