摘要： A method of creating localized haptic stimulations on a user includes a wearable device including a plurality of transducers that can each generate one or more waves that propagate away from the wearable device through a medium. The method includes activating two or more transducers of the plurality of transducers, selecting values for characteristics of waves to be generated by the two or more transducers based at least in part on a known impedance of the medium. The method further includes generating, by the two or more transducers, waves that constructively interfere at a target location to create a haptic stimulation on a user of the wearable device, the waves having the selected values.

摘要： A kinesthetic sensor measure angular displacement of body parts of users by measuring a density of substances contained in a conduit of the kinesthetic sensor. For example, the kinesthetic sensor measures the density of substance including in a conduit by transmitting a signal into the conduit and measuring the signal after the signal passes through the conduit and one or more substances included in the conduit. Based on the density of the one or more substances included in the conduit from the measured signal, an angular displacement of a user's body part proximate to the kinesthetic sensor is determined. Kinesthetic sensors may use different architectures such as an open-loop, a closed-loop architecture, or an architecture using blood vessels as conduits. Additionally, kinesthetic sensors can be flexible to conform to physical contours of different body parts.

摘要： Embodiments relate to a system and a method for providing haptic feedback to a user by controlling an area of a surface of a haptic assembly in touch (directly or indirectly) with a user. The haptic assembly can be actuated such that a surface area of the haptic assembly in contact with a user can be adjusted. An area of the haptic assembly in contact with a user can be changed by modifying a shape of the haptic assembly. Hence, by changing the shape of the haptic assembly, a user touching a virtual object in a virtual space with a particular rigidity can be emulated.

摘要： A haptic feedback glove worn by a user provides an amount of a resistance to a physical movement of a portion of the user's hand. The haptic feedback glove includes a glove body, an expandable bladder and a pressure source. The glove body includes a first portion corresponding to a first phalange of a user hand, a second portion corresponding to a second phalange of the user hand, and a third portion corresponding to a joint between the first phalange and the second phalange of the user hand. The expandable bladder is coupled to the third portion of the glove body. The expandable bladder has an adjustable size that controls an amount of relative movement between the first portion and the second portion of the glove body. The pressure source is coupled to the glove body, and is configured to adjust the size of the expandable bladder.

摘要： A haptic device provides haptic sensation to a user. The haptic device comprises a haptic plate and a plurality of actuators. The haptic plate includes a center portion and an outer portion that circumscribes the center portion. The plurality of actuators is coupled to the outer portion of the haptic plate. Of the plurality of actuators, one or more actuators are configured to generate, in accordance with haptic instructions, a haptic wave that converges to a specific waveform at a specific region of the center portion of the haptic plate. The shape of the specific waveform and the location of the specific region on the center portion of the haptic plate are based in part on the haptic instructions.

摘要： A system tracks movement of the VR input device relative to a portion of a user's skin, track movement of the VR input device relative to a physical surface external to the VR input device, or both. The system includes an illumination source integrated with a tracking glove coupled to a virtual reality console, and the illumination source is configured to illuminate a portion of skin on a finger of a user. The system includes an optical sensor integrated with the glove, and the optical sensor is configured to capture a plurality of images of the illuminated portion of skin. The system includes a controller configured to identify differences between one or more of the plurality of images, and to determine estimated position data based in part on the identified differences.

摘要： A wearable device comprises one or more deformable signaling pathways wherein each deformable signaling pathway is configured to enable an electrical connection between two devices electrically connected to each other via the deformable signaling pathway. Deformable signaling pathways enable the conduction of electrical signals between various circuit elements similar to one or more circuit elements such as electronic traces or wires. A deformable signaling pathway includes one or more conductive elements surrounded by a conductive gel. Both the conductive gel and the one or more conductive elements are encased in an elastomeric shell. The elastomeric shell is attached to terminals (e.g., one on either end). The one or more connectors are attached to one another such that the one or more connectors span the length of the elastomeric shell and form a low resistance contact between the terminals of the deformable signaling pathway.

摘要： A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.

摘要： A virtual reality system enables a user to interact with virtual objects. The system includes a fiducial ring, an imaging device and a console. The fiducial ring includes a ring body that includes a plurality of fiducial markers that each correspond to a different location on the ring body. An imaging device is configured to capture one or more images of the fiducial ring. The console receives the images that include an image of one or more fiducial markers. Based on the received images of the fiducial markers, the console determines a location on the fiducial ring that corresponds to the imaged fiducial marker. The console determines a position of the fiducial ring based on the determined location of the fiducial marker on the fiducial ring. The console provides content to a head mounted display (HMD) based on the determined position of the fiducial ring.

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 attached to an appendage of the user, a set of signals that propagate through the user's appendage and 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.
