摘要： The disclosed computer-implemented method for determining a proximity status between electrodes may include detecting an amount of electrical charge an electrode among other electrodes that are communicatively coupled to an artificial reality device. The method may further include determining, based on the detected amount of electrical charge at the electrode, a mutual capacitance measurement that indicates an amount of mutual capacitance between the other electrodes. The method may also include determining, based on the mutual capacitance measurement, a relative proximity status between the electrodes, where the relative proximity status indicates a degree to which the electrodes are in proximity with each other. The method may further include providing the determined relative proximity status between the electrodes as an input to the artificial reality device. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A haptic device comprises a wearable material configured to a portion of a user. A vibrotactile actuator is coupled to the wearable material and provides haptic feedback in accordance with a drive signal. A driver circuit is electrically coupled to the vibrotactile actuator and provides the drive signal to the vibrotactile actuator. The driver circuit includes an alternating current (AC) voltage source assembly that has a first AC voltage source and a second AC voltage source, each having a terminal. The terminal of the first AC voltage source is electrically coupled to the vibrotactile actuator. A capacitive element electrically is coupled to the terminal of the negative AC voltage source and a regulating element. The regulating element includes a first coupling point and a second coupling point. The first coupling point is electrically coupled to the capacitive element and the vibrotactile actuator, and the second coupling point is grounded.

摘要： An apparatus for creating haptic stimulations is provided. The apparatus includes an inflatable bladder and a support structure attached to a portion of the inflatable bladder. The inflatable bladder is fluidically coupled to a pressure-changing device that is configured to control a fluid pressure of the inflatable bladder. The support structure includes a predefined pattern of cuts, and is configured to expand (or otherwise deform) in one or more directions according to a design of the predefined pattern of cuts and in relation with a fluid pressure inside the inflatable bladder. When the inflatable bladder receives the fluid from the source, the inflatable bladder expands, which causes the support structure to expand in the one or more directions and also to reinforce the inflatable bladder in the one or more directions. A wearable device and a system for creating haptic simulations are also disclosed.
