1. A system comprising:

  • a sensor configured to detect a touch in a touch area when an object contacts a touch surface, the touch area mapped to a display area of a graphical user interface; and

    a processor in communication with an electrostatic actuator and the sensor, the processor configured to;

    identify text displayed in the display area responsive to a search query;

    highlight the identified text displayed in the display area in response to the search query;

    select a haptic effect to generate based on identifying a position of the touch and the highlighted identified text, wherein the haptic effect is selected to generate a haptic effect at an identified position in the touch area mapped to a position in the display area at or near the highlighted-identified text; and

    transmit a haptic signal corresponding to the selected haptic effect to the electrostatic actuator, the electrostatic actuator configured to receive the haptic signal and to generate the selected haptic effect while the touch is occurring, the haptic effect comprising adjusting a coefficient of friction of the touch surface.
