Abstract: A device configured to provide haptic feedback is disclosed. In one embodiment, at least two actuators, at distinct spatial locations, are coupled to a wearable structure configured to be worn on a portion of a user's body. The device is configured to, in response to receiving an indication from a communicatively coupled device, simultaneously actuate the at least two actuators using a first predetermined haptic signal, such that respective haptic responses generated by the at least two actuators are superimposed to generate a combined haptic response having a magnitude greater than the respective haptic responses generated by the at least two actuators.

Abstract: The disclosed haptic feedback system may include an actuator, a supply valve coupled to the actuator, an exhaust valve, and a fluidic mass controller communicatively coupled to the supply valve and the exhaust valve. The fluidic mass controller may (1) place the exhaust valve in a state that prevents a fluid from escaping the actuator, (2) activate the supply valve to fill the actuator with an amount of the fluid, (3) determine that the actuator has filled with the amount of the fluid, and then in response to that determination, (4) deactivate the supply valve to trap the amount of the fluid in the actuator. Various other apparatuses, methods, and systems are also disclosed.

Abstract: Disclosed devices may include a membrane, a first electrode supported by the membrane, a second electrode, a capacitance sensor configured to determine a capacitance measurement between the first electrode and the second electrode, and a controller configured to control an electrical potential applied between the electrode and the second electrode. The controller may be configured to modify the electrical potential based on the capacitance measurement. Example devices may include one or more flexible membranes that may, at least in part, define an enclosure that is at least partially filled with a dielectric fluid. Examples also include associated methods and systems.

Abstract: An electronic device for processing impedance changes is provided. The electronic device receives, from a wearable device that includes (i) a first biopotential-signal sensor configured to contact a first sensor-skin interface when the wearable device is worn on a body part of a user, and (ii) a second biopotential-signal sensor configured to contact a second sensor-skin interface when the wearable device is worn on the body part of the user, data indicating impedance values at the first and second sensor-skin interfaces. The method further includes, after physical contact by an object other than the body part with or near the body part of the user, based on obtaining (i) a first impedance change at the first sensor-skin interface and (ii) a second impedance change at the second sensor-skin interface, determining whether the physical contact corresponds to a user command to control the wearable device or another electronic device.

Abstract: Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to determining that a representation of a user's finger is located within a predefined distance of an input element: obtaining information regarding an amount of force needed to actuate the input element, and causing adjustment of a physical characteristic of an actuator while the actuator is associated with the input element. The method further includes, in response to an input having at least the amount of force applied by the user's finger to a component of the actuator while the actuator is associated with the input element, causing an input command to be performed and providing a haptic response via the actuator component.
