HAPTICS APPLICATION PROGRAMMING INTERFACE

Abstract:

Systems and methods are disclosed defining haptic patterns that include both haptic events and audio events, and optionally include video or animation. The haptic patterns can be called from an application or included as an attachment to a message and played on an electronic device that receives the message. A haptics application programming interface has a haptic experience mapping functionality that generates a same, or similar, haptic experience on different manufacturers or models of electronic devices having different haptic hardware. Haptic patterns can include synchronized haptic and audio events. Haptic event attributes include start time, sharpness, and intensity. Sharpness and/or intensity can be controlled via a parameter envelope for a single event, or for multiple events in a haptic pattern. Sharpness indicates a quality of the tactile sensation of a haptic event, from smooth or rounded, to sharp or precise.
