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： Systems and methods for integrating haptics overlay in augmented reality are disclosed. One illustrative system described herein includes a haptic output device. The system also includes a display configured to output a visual effect. The system also includes a sensor for tracking a position of a proxy object. The system also includes a processor configured to: determine a modified visual effect based in part on data received from the sensor, determine a haptic effect based in part on data received from the sensor, transmit a display signal associated with the modified visual effect to the display, transmit a haptic signal associated with the haptic effect to the haptic output device; and output the haptic effect using the haptic output device.

摘要： Systems and methods for multi-rate control of haptic effects with sensor fusion are disclosed. One illustrative system includes, a haptic output device configured to output a haptic effect, a first sensor configured to sense the output of the haptic output device and generate a first sensor signal, a processor in communication with the first sensor. The processor is configured to: sample the first sensor signal from the first sensor at a first rate, receive a reference signal, determine an error between the first sensor signal and the reference signal, generate a haptic signal based at least in part on the reference signal and the error, transmit the haptic signal to a haptic output device configured to output a haptic effect based on the haptic signal, and sample the first sensor signal at a second rate, wherein the second rate is lower than the first rate.

摘要： A haptic-enabled display device is presented. The haptic-enabled device has a display layer, a first electrode layer, an actuation layer, and an electrode patch. The first electrode layer is disposed on the display layer. The actuation layer is formed of a single piece of actuatable material. A first side of the actuation layer is disposed on the first electrode layer. The single piece of actuatable material of the actuation layer and the conductive material of the first electrode layer may have substantially the same area. The electrode patch may form a second electrode layer, and may be disposed on a second and opposite side of the actuation layer. The electrode patch is electrically connected to a region of the actuatable material, and has an area that is smaller than that of the single piece of actuatable material and smaller than that of the conductive material of the first electrode layer.
