摘要： In aspects, methods and apparatus are provided for generating a haptic effect for a three-dimensional (3D) environment that is experienced virtually by a user. The methods may be performed by a processor, and includes receiving media data that describes the 3D environment, wherein the media data includes haptic data which describes a haptic characteristic associated with at least one object, structure, or event in the 3D environment. The method further includes performing a haptic decoding operation and a haptic rendering operation. The decoding operation may include extracting the haptic data from the media data. The haptic rendering operation may include generating a drive signal and communicating the drive signal to a haptic output device to cause the haptic output device to generate a haptic effect at a user peripheral device. Numerous other aspects are provided.

摘要： Systems, methods, and devices for control of actuators are provided. In aspects, the systems, methods, and devices provided herein enable the generation of sharp cutoff haptic effects of both limited and extended duration. The systems, methods, and devices use open loop braking signals to generate the sharp cutoff haptic effects. The braking signals are determined based on predictions of system response made according to driving signals used to cause the haptic effects in the actuators. Numerous other aspects are provided.

摘要： In aspects, zoned haptic effects are provided by assigning a plurality of zones corresponding to each of a plurality of zone actuators for providing haptic effects. A desired haptic response is provided for zones selected for actuation, and the response by the zone actuators is detected. Adjacent and non-adjacent zones are assigned for the detected zones as being driven by any of the plurality of zone actuators. Vibration on the adjacent and non-adjacent zone is suppressed in accordance with control parameters associated with the respective adjacent and non-adjacent zones. If a duration of the provided haptic effect has not passed, the suppression of vibration in the adjacent and non-adjacent zones is maintained and if the duration has passed, the suppression of vibration is terminated. Numerous other aspects are provided.

摘要： Systems and methods for integrating environmental haptic effects in virtual reality are disclosed. One illustrative system described herein includes a sensor for detecting an environmental condition, the environmental condition associated with an environmental haptic effect, and generating a sensor signal. The system also includes a virtual reality display configured to output a virtual reality effect. The system also includes a processor coupled to the sensor and a virtual reality display, the processor configured to: receive the sensor signal, determine a modification to the virtual reality effect based in part on the sensor signal, and transmit a display signal associated with the modification to the virtual reality display. Another illustrative system includes a sensor for detecting an environmental condition, the environmental condition associated with an environmental haptic effect, and generating a sensor signal, and a virtual reality display configured to output a virtual reality effect. The system also includes a processor coupled to the sensor and a virtual reality display, the processor configured to: receive the sensor signal, determine a generated haptic effect based at least in part of the sensor signal that when combined with the environmental haptic effect produces the desired haptic effect, and transmit a haptic signal associated with the generated haptic effect to a haptic output device.

摘要： The embodiments of the present invention enable novel methods, non-transitory mediums, and systems for encoding and generating haptic effects. According to the various embodiments, a media object is retrieved. The media object is analyzed to determine one or more time periods for rendering haptic effects. The haptic effects for rendering during the time periods are determined. The haptic effects are encoded as a haptic effect pattern that identifies a start time and duration for each of the haptic effects.

摘要： Systems, methods, and devices include at least one actuator positioned within proximity of a user interface (UI) region of an interactive surface. The UI region outputs information to a user and receives input from the user. The at least one actuator provides a haptic effect to the user when interacting with the UI region. The system also includes at least one isolation element positioned adjacent to the at least one actuator. The at least one isolation element suppresses transmission of the haptic effect to an additional UI region of the interactive surface.

摘要： Systems, devices, and methods for encoding haptic tracks are provided. A method includes receiving the haptic track, and identifying, within the haptic track, at least one of first portions of the haptic track that are representative of haptic silences or second portions that are representative of haptic effects. The method includes segmenting the haptic track into haptic silence chunks associated with one or more of the first portions that are sequentially positioned in the haptic track and haptic effects chunks associated with one or more of the second portions that are sequentially positioned in the haptic track. The method includes generating an encoded haptic track comprising at least one of a haptic silence block or a haptic effect block. The method includes outputting the encoded haptic track for playback. Numerous other aspects are provided.
