Abstract
Providing haptic feedback includes a first electrode, a second electrode, an electroactive polymer located between the first electrode and the second electrode such that when a voltage is applied between the electrodes, the electroactive polymer expands creating a force, and a haptic object to apply the force to create the haptic feedback, wherein the haptic object includes a base to receive the force from the electroactive polymer, and a vertex, opposite to and with a smaller surface area than the base, to apply localized haptic feedback to a user.
