    Abstract: A haptic-enabled user interface device comprising a user input component, an elastomer suspension, a signal generating circuit, a signal sensing circuit, one or more switches, and a control unit is presented. The elastomer suspension is formed by at least one stack that includes an elastomeric layer, wherein the at least one stack forms at least one capacitor. The control unit is configured, in an actuation mode, to cause the one or more switches to electrically connect the signal generating circuit to the at least one capacitor and to electrically disconnect the signal sensing circuit from at least one capacitor, and to cause the signal generating circuit to apply a drive signal to the at least one capacitor. The control unit is further configured, in a sensing mode, to cause the one or more switches to electrically connect the signal sensing circuit to the at least one capacitor.

    Abstract: One example device according to this disclosure includes a housing sized to be grasped by a hand; a shape-change element disposed at least partially within the housing; and a plurality of actuators disposed within the housing, the plurality of actuators arranged to rotate and translate the shape-change element. An example method for multi-degree-of-freedom shape-changing devices includes determining a shape-change haptic effect to output to a shape-change device, the shape-change device comprising a housing and at least one shape-change element disposed at least partially within the housing, the shape-change haptic effect comprising a translation and a rotation of the shape-change element; generating a haptic signal based on the shape-change haptic effect; and transmitting the haptic signal to one or more actuators of a plurality of actuators to cause the shape-change haptic effect, the plurality of actuators arranged to translate and rotate the shape-change element.

    Abstract: A haptically-enabled controller device comprising a controller body, a user input element, a haptic actuator, and a transmission component is presented. The user input element has a range of motion that extends from a first position to an end stop position. The haptic actuator is configured to output a force or torque. The transmission component comprises an arm connected to the haptic actuator and to the user input element. The arm is configured to transfer the force or torque from the haptic actuator to the user input element with a first multiplication factor when the user input element is at the first position, and to transfer the force or torque from the haptic actuator to the user input element with a second multiplication factor when the user input element is at the end stop position. The second multiplication factor is higher than the first multiplication factor.

    Abstract: 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.

The elastomer suspension is formed by at least one stack that includes an elastomeric layer, wherein the at least one stack forms at least one capacitor. The control unit is configured, in an actuation mode, to cause the one or more switches to electrically connect the signal generating circuit to the at least one capacitor and to electrically disconnect the signal sensing circuit from at least one capacitor, and to cause the signal generating circuit to apply a drive signal to the at least one capacitor. The control unit is further configured, in a sensing mode, to cause the one or more switches to electrically connect the signal sensing circuit to the at least one capacitor.
