Abstract

An electronic damping feedback control system for an electroactive polymer module, an electroactive polymer device, and a computer-implemented method for creating realistic effects are provided. The electronic damping controller is coupled in a feedback loop between a user interface device and an electroactive polymer actuator, where the actuator is coupled to the user interface device. The electronic damping controller is configured to receive an actuation signal from the user interface device in response to a user input. In response to the actuation signal, the electronic damping controller generates an electronic damping signal to couple to the actuator. The electroactive polymer device includes a user interface device, an electroactive polymer actuator coupled to the user interface device, and the electronic damping controller.; The present invention may provide improved user interface devices.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 USC § 119(e) of the following U.S. Provisional Patent Application Number: 61 filed March 9, 2011, entitled "ELECTROACTIVE POLYMER HAPTIC ACTUATOR UTILIZING ELECTRONIC DAMPING FOR IMPROVED KEY CLICK REPLICATION ON TOUCHSCREEN" / 450,772, and 61 / 472,777, entitled "METHOD OF CREATING REALISTIC HAPTIC EFFECTS," filed April 7, 2011, the entire disclosures of each of which are hereby incorporated by reference in their entirety. technical field [0003] In various embodiments, the present disclosure relates generally to user interface devices, and more specifically to utilizing electronic damping to improve "key click" replication on devices commonly used by users to interface with computers and mechanical devices . The present disclosure also relates to methods of creating a realistic haptic response when a user touches a surface, presses a button or key, or turns a knob. Backgrou...
