摘要： Devices and methods for providing localized haptic effects are provided. The devices include a haptically enabled display device having one or more haptic actuators. The one or more haptic actuators are located in a non-viewing area of a display screen of a haptically enabled display device and cause localized haptic effects in a viewing area of the display screen. The haptically enabled display device includes a processor configured to determine haptic control signals for activating the haptic actuators. The haptic control signal activates the one or more haptic actuators to provide a localized haptic effect at a target location in the viewing area, remote from the non-viewing area location of the one or more haptic actuators.

摘要： Systems, devices, and methods for providing limited duration haptic effects are disclosed. Systems for providing limited duration haptic effects include sensors, control circuits, and vibration actuators configured closed loop feedback control of the vibration actuators. The sensors are configured to measure motion characteristics induced by the vibration actuators. The control circuits are configured to receive motion characteristic information from the sensors and provide closed loop feedback control of the vibration actuators. Closed loop feedback control permits precise control of vibration actuator output during limited duration haptic effects.

摘要： A flexible user interface device comprising a flexible body, a flex sensor, and a control unit is presented. The flex sensor is configured to sense the flexible body receiving an external flexing force. The control unit is configured to detect the flexible body receiving the external flexing force, to determine whether to generate resistive feedback that resists the external flexing force, and to cause the flexible body to increase in stiffness so as to resist the external flexing force. The stiffness is increased via an air sac, a layer of actuatable material such as a macrofiber composite material, electrostatic adhesion, electromagnetic attraction, micro-wedges, or in some other manner.

摘要： In aspects, methods and apparatus are provided for the generation of haptic command signals to cause haptic effect outputs at one or more haptic output devices. The haptic command signals may be generated based on haptic media, supplementary media, and/or haptic device capability. Generating the haptic command signals may include creation or modification of haptic effects, distribution of haptic effects, and/or warping of haptic signals. The methods and apparatus may operate according to combinations of developer provided rules and system enabled inferences. Numerous other aspects are provided.

摘要： A bi-functional apparatus for sensing touch and delivering a haptic signal. The bi-functional apparatus comprises first and second electrodes. The first electrode provides a haptic interface for delivering an electrostatic force and has a top surface and a bottom surface. A dielectric insulator covers the top surface of the first electrode. A sensor is positioned between the bottom surface of the first electrode and the second electrode. The sensor selectively provides electrical conductivity between the first and second electrodes in response to at least a threshold amount of pressure exerted against the dielectric insulator. A method of sensing touch and delivering a haptic signal with a single device. The method comprises receiving an input at a touch surface of a dielectric insulator layered over a first electrode; in response to receiving the input at the touch surface, increasing the electrical conductivity of a sensor positioned between the first electrode and a second electrode; in response to increasing electrical conductivity of the sensor, conducting an electrical current between the first and second electrodes; and in response to conducting an electrical current between the first and second electrodes, applying a haptic drive signal to the first electrode, the haptic drive signal creating an electrostatic force in the dielectric insulator.

摘要： A haptic actuator assembly includes a haptic actuator configured to output displacement along a perpendicular axis and a pre-load device. The pre-load device is disposed adjacent to the haptic actuator and configured to generate a compressive load on the haptic actuator along the perpendicular axis to oppose expansion of the haptic actuator along the perpendicular axis. The pre-load device includes a casing and at least a first spring component. The casing includes a cover and a base spaced apart from and extending parallel to the cover. The haptic actuator is disposed between the cover and the base, and the first spring component is configured to exert a force in order to create the compressive load on the haptic actuator along the perpendicular axis.

摘要： A system receives a multiplexed signal with two or more different types of haptic signals encoded therein. Each type of haptic signal represents a haptic effect for different types of haptic output devices. The system determines a target haptic output device located on a haptic playback device. The system demultiplexes the multiplexed signal into at least the type of haptic signal corresponding to the target output device. The system provides the demultiplexed haptic signal to the target haptic output device.

摘要： In aspects, zoned haptic effects are provided by assigning a plurality of zones corresponding to each of a plurality of zone actuators for providing haptic effects. A desired haptic response is provided for zones selected for actuation, and the response by the zone actuators is detected. Adjacent and non-adjacent zones are assigned for the detected zones as being driven by any of the plurality of zone actuators. Vibration on the adjacent and non-adjacent zone is suppressed in accordance with control parameters associated with the respective adjacent and non-adjacent zones. If a duration of the provided haptic effect has not passed, the suppression of vibration in the adjacent and non-adjacent zones is maintained and if the duration has passed, the suppression of vibration is terminated. Numerous other aspects are provided.
