Abstract
A haptic feedback device includes a signal generation module configured to output a composite signal representable by a carrier signal and an envelope signal. The signal generation module includes a microcontroller capable of being programmed such that the carrier signal falls within a resonance frequency band of the haptic feedback device. The haptic feedback device also includes a user interface device, and a transducer configured to impart haptic force to the user interface device in response to the composite signal. A tactile mapping submodule, a duration mapping submodule, and an attack/decay mapping submodule may also be included. The tactile mapping submodule enables compensation for haptic output at different positions on the haptic feedback device, whereas the duration and attack/decay submodules enable prevention of unwanted audio output.
