Abstract
An electronic device that is operable to provide electrical haptic output includes a touch surface and multiple haptic cells disposed on the touch surface. The multiple haptic cells include capacitors that are operable to store charges independently of each other and independently provide haptic output when touched by a body by discharging the stored charge to create a current. In this way, a wide variety of dynamically configurable haptic outputs can be provided without moving parts and without consuming the space and/or power used for haptic actuators that vibrate and/or otherwise move a mass.
