  • Publication number: 20190041990
    Abstract: Systems and methods for rendering a haptic effect at a user input element associated with a haptic output device are provided. A primary range and a secondary range of positions are defined for the user input element associated with the haptic output device. In addition, a boundary range of positions is defined for the user input element associated with the haptic output device, the boundary range partially overlapping each of the primary and secondary ranges. A position of the user input element is monitored, and the haptic effect rendered in response to an entry of the user input element to positions within the boundary range.

  • Publication number: 20180321751
    Abstract: The embodiments are directed toward techniques for isolating a user input signal at a haptic output device. A signal originating from a user input element associated with the haptic output device is received. The received signal is separated into a first component including the user input signal, and a second component including a haptic feedback signal. While the first component is processed, the second component can be discarded or otherwise ignored.

  • Publication number: 20160179220
    Abstract: Systems and methods for controlling power and/or current consumption for multiple haptic output devices are provided. Various features of the haptic output device may be described within a data structure. In response to a haptic instruction, a power budget for the haptic output device may be determined in accordance with its operational characteristics. A drive signal may then be applied to the haptic output device to produce the haptic effect in accordance with the calculated power budget. The calculated power budget may be configured to limit the current or power drawn by the haptic output device.

  • Patent number: 9196135
    Abstract: A haptic drive circuit includes a voltage input for receiving input power, a gate that compares a desired current level to an actual current level through the actuator, a switch coupled to the gate that interrupts or provides power from the voltage input to the actuator, and a current probe that detects the actual current level through the actuator with an output signal corresponding to the actual current level coupled to the gate. The gate compares the actual current level to the desired current level and causes the switch to interrupt input power when the actual current level is greater than the desired current level or to provide input power when the actual current level is less than or equal to the desired current level. The actual current through the circuit is a haptic signal causing a haptic actuator to generate a haptic effect.
