Haptic authoring tool for animated haptic media.
Abstract
Systems, methods, and computer program products to perform an operation comprising receiving input specifying one or more positional and dimensional properties of a first haptic animation object in an animation tool displaying a representation of a vibrotactile array comprising a plurality of actuators configured to output haptic feedback, computing, based on a rendering algorithm applied to the first haptic animation object, a vector profile for each of the actuators, and computing an intensity value for each of the actuators based on the vector profile of the respective actuator.
Background
BACKGROUND(1) Field of the Invention(2) Embodiments disclosed herein relate to haptic feedback. More specifically, embodiments disclosed herein provide authoring tools for animated haptic media production.(3) Description of the Related Art(4) Haptic feedback has added a new dimension to modern entertainment and media applications, enhancing user interaction and immersion. Recent haptic technologies supplement movies, applications, games, and social activities with coherent and synchronized cues, creating dynamic and engaging haptic effects perceived by a user's body. However, these technologies have seen limited adoption, partly due to a dearth of haptic authoring tools that allow artists and designers to create rich haptic content. Similarly, any existing tools are not able to generate content that is universally applicable to the varying types of haptic hardware. In addition, most existing tools are designed for a single actuator, and those that accommodate multiple actuators require individual control of each actuator. These multi-track authoring tools are cumbersome and complicated for systems having dozens of actuators.SUMMARY(5) Embodiments disclosed herein include systems, methods, and computer program products to perform an operation comprising receiving input specifying one or more positional and dimensional properties of a first haptic animation object in an animation tool displaying a representation of a vibrotactile array comprising a plurality of actuators config
