Abstract
A haptic output device includes a touch surface, a sensor configured to sense an input at the touch surface, and a controller configured to read the sensor, identify a location of the input, switch from a read mode to a write mode, and write a voltage based on the location of the input to generate an electrostatic output.

1-20. (canceled)
A haptic output device comprising:
- an insulating layer forming a surface of the haptic output device;
- one or more electrodes;
- a sensor configured to sense a touch input at the surface of the haptic output device;
- and
- a control circuit configured
- to sense, via the sensor, the touch input on the surface of the haptic output device,
- to determine a size of a contact area between an object applying the touch input and the surface of the haptic output device, and
- to apply an electric signal to at least one electrode of the one or more electrodes to generate an electrostatic output with the at least one electrode, wherein a level of the electric signal is based on the size of the contact area between the object applying the touch input and the surface of the haptic output device.

A haptic output device comprising:
- an insulating layer forming a surface of the haptic output device;
- one or more electrodes;
- a sensor configured to sense a plurality of touch inputs at the surface of the haptic output device;
- and
- a control circuit configured
- to sense, via the sensor, a location of a first touch input of the plurality of touch inputs and a location of a second touch input of the plurality of touch inputs, and
- to apply an electric signal to at least one electrode of the one or more electrodes to generate an electrostatic output with the at least one electrode, wherein a level of the electric signal is based on the location of the first touch input relative to the location of the second touch input, wherein the electric signal causes the at least one electrode to generate an electrostatic output.

A haptic output device comprising:
- an insulating layer forming a surface of the haptic output device;
- a plurality of electrodes comprising at least a first electrode and a second electrode;
- a sensor configured to sense a touch input at the surface of the haptic output device;
- and
- a control circuit configured
- to sense, via the sensor, a location of the touch input on the surface of the haptic output device,
- to determine whether the location of the touch input is over the first electrode or is between the first electrode and the second electrode,
- to write an electric signal to the first electrode to generate an electrostatic output with the first electrode, wherein the electric signal is applied at a first level if the location of the touch input is over the first electrode, and wherein the electric signal is applied at a second level different than the first level if the location of the touch input is between the first electrode and the second electrode.
