  • 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.

  • 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: 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.
