摘要： 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.

摘要： A signal associated with multiple haptic effects is received, each haptic effect from the multiple haptic effects being associated with a time slot from multiple time slots. Each haptic effect from the multiple haptic effects is associated with an effect slot from multiple effect slots at least partially based on the time slot associated with that haptic effect. An output signal is sent for each effect slot from the multiple effect slots, when the associated haptic effect is scheduled for its time slot.

摘要： 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. The processor can transmit a haptic signal to generate the identified haptic effect using the actuator. Some features are simulated by varying the coefficient of friction of the touch surface.

摘要： A system for generating a haptic effect with an electrostatic device, alone or in combination with actuators or other devices configured to generate a haptic effect. The system may generate the haptic effect to simulate a coefficient of friction or texture on the surface of a user interface, such as a display screen or touchpad. The simulated coefficient of friction may be adjusted to convey other properties on the user interface surface. The system may also include sensors that measure the simulated coefficient of friction and the impedance at the surface.
