摘要： A support structure includes a fixed frame portion configured to provide a fixed connection point for the support structure. The support structure also includes a suspended frame portion configured to support the interactive device and configured to oscillate in a direction of motion relative to the fixed frame portion due to a force applied to at least one of the fixed frame portion or the suspended frame portion by an actuator configured to provide a haptic effect to the interactive device. Further, the support structure includes one or more support members coupled between the fixed frame portion and the suspended frame portion. The direction of motion is defined by the one or more support members. The one or more support members provide a restoring force that causes the suspended frame portion to undergo harmonic oscillation in the direction of motion in response to the force applied by the actuator.

摘要： A non-transitory computer-readable medium for generating a haptic effect is provided. The computer-readable-medium has computer-executable code that causes a processor to receive a desired haptic effect waveform for the haptic effect, to receive sensor information that indicates at least one of speed, acceleration, and position of the haptic output device, and to generate a control signal for the haptic effect based on the desired haptic effect waveform and the at least one of the speed, acceleration, and position of the haptic output device, wherein the control signal causes a profile of the haptic effect to substantially match the desired haptic effect waveform, such that matching between the profile of the haptic effect and the desired haptic effect waveform is made more similar by basing the control signal on the at least one of the speed, acceleration, and position of the haptic output device.

摘要： 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.

摘要： The embodiments are directed toward an architecture and communication protocol for controlling haptic output devices. According to the embodiments, a composite drive signal is generated that includes a first drive signal to be rendered by a first haptic output device, a second drive signal to be rendered by a second haptic output device, and a packet identifier. A controller includes the first haptic output device that is associated with a first user input element and the second haptic output device associated with a second user input element. The composite drive signal is transmitted to controller, and the execution order of the first and second drive signals is determined based on the packet identifier.

摘要： A user interface device having a haptic actuator, a sensor, a storage device, and a control circuit is presented. The sensor is configured to measure movement output by the haptic actuator. The control circuit is configured to apply a first drive signal to the haptic actuator to generate a first haptic effect, and to receive a sensor measurement that describes movement of the haptic actuator in response to the first drive signal, and to generate or update, based on the measurement, an actuator model that describes how the haptic actuator moves in response to drive signals. The control circuit is further configured to generate a second drive signal based on a desired movement for a second haptic effect and based on the actuator model, and to control the haptic actuator to generate the second haptic effect by applying the second drive signal to the haptic actuator.

摘要： In each of the various embodiments, a haptic driver is configured to attenuate a drive signal of an actuator. In particular, the haptic drivers described herein are configured to identify the resonance frequency of the actuator and to attenuate the haptic drive signal within a range of frequencies, the range being based on the identified resonance frequency. As a result, the strength of haptic effects produced by the actuator may be more uniform along a wider frequency range.

摘要： 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.

摘要： An apparatus, such as a haptic-enabled device, and a method for providing boost protection logic are presented. The method comprises receiving, by a control circuit of the apparatus, a nonzero drive signal to be used by the haptic actuator to generate a haptic effect. The control circuit causes a first portion of the nonzero drive signal to be applied to the haptic actuator in a boost mode. The control circuit detects a boost duration exceeding a first defined time threshold, such as a boost timeout threshold, or detects an accumulated boost time exceeding the first defined time threshold. In response, the control circuit causes a second portion of the nonzero drive signal to be applied to the haptic actuator in an amplitude-limited mode.
