摘要： A method creates haptic stimulations on a user of an artificial reality system. The system includes a head-mounted display (HMD) and a wearable device. The HMD includes a display and speakers. The wearable device includes a plurality of transducers that can each generate waves to provide haptic feedback to a user. The system displays media content on the display and, in accordance with the displayed media content, determines a virtual object location in the displayed media content corresponding to a physical object location. The system provides, to the user, audio directed to the virtual object location. The system activates one or more transducers to provide haptic feedback at a target location on the user, distinct from the physical object location, to produce haptic feedback whose perceptual interpretation is at the physical object location based on a combination of the displayed media, the provided audio, and the haptic feedback.

摘要： A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic devices comprise a gate, a channel, and an obstruction. The gate comprises at least one chamber whose volume increases with fluid pressure. A high-pressure state of the gate corresponds to a first chamber size and a low-pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size. The obstruction controls a rate of fluid flow within the channel based on the fluid pressure in the gate. The obstruction induces at most a first flow rate of fluid in the channel in accordance with the low-pressure state of the gate, and at least a second flow rate of the fluid in the channel in accordance with the high-pressure state of the gate.

摘要： An example method of identifying a touch gesture on a user is provided. The method includes receiving, by one or more transducers of a wearable device, a set of signals that establish a signal pathway to the wearable device. The method also includes, while receiving the set of signals, determining baseline characteristics for the signal pathway, and sensing a change in the baseline characteristics caused by user interaction with an affordance of a user interface projected or perceived on the user's appendage. The method further includes, in accordance with a determination that the sensed change in the baseline characteristics satisfies a contact criterion, reporting a candidate touch event on the user's appendage to a separate electronic device that creates the user interface or is in communication with another electronic device that creates the user interface.

摘要： A deformation sensing apparatus comprises an elastic substrate, a first strain-gauge element formed on a first surface of the elastic substrate, and configured to output a first signal in response to a strain applied in a first direction, and a second strain-gauge element formed on a second surface of the elastic substrate opposite to the first surface, and configured to output a second signal in response to a strain applied in the same first direction.

摘要： A fluidic device controls fluid flow in channel from a source to a drain. The fluidic device may be combined with other fluidic devices to form different types of logic devices g an inverter, OR gate, etc.). And the logic devices may be incorporated into an artificial reality system (e.g., as part of a haptic assembly). In some embodiments, a fluidic device includes a gate, a channel, and a wedge. The wedge controls a rate of fluid flow within the channel based on a fluid pressure in the gate. The wedge induces a first flow rate of fluid in the channel in accordance with a low pressure state of the gate, and a second flow rate of the fluid in the channel in accordance with a high pressure state of the gate, the second flow rate greater than the first flow rate.

摘要： An input interface configured to be worn on a portion of a user's body includes tendons coupled to various sections of the glove. A tendon includes one or more activation mechanisms that, when activated, prevent or restrict a particular range of motion. Additionally, a tendon may be coupled to a plate that is coupled to one or more additional tendon, so when an activation mechanism included in the tendon is activated, the one or more additional tendons coupled to the plate that are also coupled to the tendon move, stiffening the additional tendons as well as the tendon.

摘要： The disclosure describes a fluidic oscillator. The fluidic oscillator is configured to oscillate between a closed state and an open state. The fluidic oscillator comprises an oscillator conduit forming an oscillator chamber comprising an inlet and an outlet wherein the inlet and the outlet are configured to enable fluid flow through the oscillator chamber. An inner chamber of the oscillator chamber further includes a flexible element wherein a rate of fluid flow through the oscillator chamber results in a deformation in the flexible element. In other elements, the fluid oscillator further comprises two fluidic gates comprising a deformable chamber wherein changes in a control pressure of a control fluid in the deformable chamber results in a deformation in a volume of the oscillation chamber.

摘要： A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic device comprises a channel and a gate. The channel is configured to transport a fluid from the source to the drain. The gate controls a rate of fluid flow in the channel in accordance with the fluid pressure within the gate. Specifically, the gate is configured to induce a first flow rate of the fluid in the channel in accordance with a low pressure state of the gate, and a second flow rate of the fluid in the channel in accordance with a high pressure state of the gate. In certain embodiments, the first flow rate is greater than the second flow rate. In alternative embodiments, the second flow rate is greater than the first flow rate.

摘要： A system modifies data generating haptic feedback to account for changes in user perception of haptic feedback. The system identifies haptic data and determines an estimated amplitude of haptic feedback corresponding to a portion of the haptic data. Responsive to the estimated amplitude of the haptic feedback corresponding to the portion of the haptic data exceeding a threshold value, a refractory period is determined that will occur after haptic feedback corresponding to the portion of the haptic data is applied to the user. The portion of the haptic data is provided to an input interface, and a set of haptic data associated with times within a duration of the refractory period from the identified haptic data is removed to form an adjusted data set that is provided to the input interface to provide haptic feedback to the user in accordance with adjusted haptic data set.
