    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: 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, 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.

    摘要: A haptic effect enabled flexible device is presented that includes a flexible frame, a processor, a flexible display and an actuator system. The processor is configured to receive a data stream where the data stream contains visual content. The flexible display is connected to the flexible frame and is designed to display the visual content from the data stream. The actuator system is also connected to the flexible frame and receives drive commands from the processor as a result of the processor executing a plurality of haptic instructions. The drive commands direct the actuator system to deform the flexible device. Execution of the plurality of haptic instructions is synchronized with the display of the visual content on the flexible display device.

    摘要: Systems and methods for force sensors for haptic surfaces are disclosed. One disclosed system includes a support; a touch surface configured to detect contact with the touch surface and output one or more contact signals indicating a location of the contact; a pivot mechanism coupled to the touch surface and the support, the pivot mechanism enabling the touch surface to rotate about a pivot axis; a sensor positioned to detect a force associated with the contact and to transmit one or more sensor signals indicating the force; a non-transitory computer-readable medium; and a processor in communication with the sensor and the non-transitory computer-readable medium, the processor configured to execute processor-executable instructions stored in the non-transitory computer-readable medium to: receive the one or more sensor signals and the one or more contact signals; and a contact force exerted on the touch surface based on one or more of the contact signals and one or more of the sensor signals.
