  • Publication number: 20200257370
    Abstract: Systems and methods for multi-rate control of haptic effects with sensor fusion are disclosed. One illustrative system includes, a haptic output device configured to output a haptic effect, a first sensor configured to sense the output of the haptic output device and generate a first sensor signal, a processor in communication with the first sensor. The processor is configured to: sample the first sensor signal from the first sensor at a first rate, receive a reference signal, determine an error between the first sensor signal and the reference signal, generate a haptic signal based at least in part on the reference signal and the error, transmit the haptic signal to a haptic output device configured to output a haptic effect based on the haptic signal, and sample the first sensor signal at a second rate, wherein the second rate is lower than the first rate.

  • Patent number: 10741189
    Abstract: Embodiments that generate multiple haptic effects receive a first haptic effect signal having a first priority and corresponding to a first haptic effect, and receive a second haptic effect signal having a second priority and corresponding to a second haptic effect. When the first priority is less than the second priority, embodiments generate an interaction parameter using the second haptic effect signal. When the second priority is less than the first priority, embodiments generate the interaction parameter using the first haptic effect signal. Embodiments then apply a drive signal to a haptic output device according to the interaction parameter, where the drive signal causes the first haptic effect and the second haptic effect to be generated by the haptic output device concurrently.

  • Patent number: 10650859
    Abstract: A system includes a recorder configured to record audio and/or video of a subject of interest and output a recording of the subject of interest and a non-contact sensor associated with the recorder. The non-contact sensor is constructed and arranged to measure movement and/or vibration of the subject of interest from substantially the same perspective and at the same time as the recorder. The system includes a controller configured to transform the measured movement and/or vibration of the subject of interest measured by the non-contact sensor into a tactile data stream for sending to a haptic display device for playback with the recording of the subject of interest by the recorder and providing haptic effects corresponding to the measured movement and/or vibration to a user of the haptic display device in synchronization with the recording.

  • Publication number: 20200142487
    Abstract: The disclosure relates to systems and methods of providing haptic feedback based on media content and one or more external parameters used to customize the haptic feedback. The system may modify or otherwise alter haptic feedback that is determined using the media content alone. In other words, the system may use both the media content and the external parameters to determine haptic feedback that should be output to the user or others. The external parameters may include, for example, sensor information, customization information, and/or other external parameters that may be used to customize the haptic feedback.

  • Patent number: 10591995
    Abstract: A gaming concept in which each user in a single-player or a multi-player game is enabled to create artwork or graffiti work virtually or on actual surfaces using haptic-enhanced controllers. The controllers can emulate the experience of using a marker, a paint brush, a paint spray-can or the like. The components of various controllers may be modularized for easily interchanging components to extend the art or graffiti creation experience. The real life experience of using ink or paint on a surface is simulated by haptic feedback. When a paint spray-can controller is used, the experience of paint consumption is recreated by various peripheral enhancements including audio and haptic sensations communicated to the user.

  • Patent number: 10529197
    Abstract: A system is provided that controls an offline haptic conversion. The system receives an input from a source. The system further converts the input into haptic signals. The system further encodes the haptic signals. The system further stores the haptic signals within the source, where the haptic signals are combined with the input within the source. Alternately, rather than encoding the haptic signals and storing the haptic signals within the source, the system handles the haptic signals separately, independent of the source.
