  • Patent number: 10748389
    Abstract: An apparatus and method for damping haptic vibrations. A haptic output device is positioned within a device housing. The haptic output device has a haptic actuator and a haptic mass, the haptic mass being movable relative to the housing. A damper is positioned within the device housing. A controller is programmed to generate and deliver a haptic signal to the haptic actuator at a first time, and to generate and deliver a damping signal to the damper at a second time, the second time occurring after the first time. The method comprises moving a haptic mass, the haptic mass position in a housing; vibrating the housing in response to moving the haptic mass; damping movement of the haptic mass after a period of time; and substantially eliminating vibration of the housing in response to damping movement of the haptic mass.

  • Patent number: 10747322
    Abstract: A touch-enabled device can simulate one or more features in a touch area. Features may include, but are not limited to, changes in texture and/or simulation of boundaries, obstacles, or other discontinuities in the touch surface that can be perceived through use of an object in contact with the surface. Systems include a sensor configured to detect a touch in a touch area when an object contacts a touch surface, an actuator, and one or more processors. The processor can determine a position of the touch using the sensor and select a haptic effect to generate based at least in part on the position, the haptic effect selected to simulate the presence of a feature at or near the determined position. Some features are simulated by varying the coefficient of friction of the touch surface.

  • Publication number: 20200218356
    Abstract: One illustrative system disclosed herein includes a computing device that comprises a memory and a processor in communication with the memory. The system also includes an xPC target machine that is capable of achieving sampling rates of at least 100 khz and in communication with the computing device and a user device that includes a sensor and a haptic output device. The processor generates a simulate reality environment and determines a haptic effect based on the simulated reality environment or a sensor signal from the sensor. The processor transmits data about a parameter of the haptic effect or the sensor signal to the xPC target machine, which determines the parameter of the haptic effect and generates, in substantially real time, a haptic signal. The xPC target machine transmits the haptic signal to the haptic output device, which is configured to receive the haptic signal and output the haptic effect.

  • Patent number: 10620707
    Abstract: Systems and methods for interfaces featuring surface-based haptic effects are described. One described system includes a sensor configured to detect a touch in a touch area when an object contacts a touch surface. The touch surface may correspond to the display area or may correspond to a non-display surface of a computing device or peripheral interfaced to a computing device. The system can further include an actuator in communication with the processor and coupled to the touch surface, the actuator configured to output a haptic effect and a processor configured to select a haptic effect to generate. The haptic effect can be selected based on a position of the touch and recognizing an input gesture provided by the touch and/or content displayed in a graphical user interface at a location mapped to a position in the touch area at or near the touch. The haptic effect may provide a texture, simulate an obstacle, and/or adjust the coefficient of friction of the surface.
