  • Patent number: 11068057
    Abstract: 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.

  • Patent number: 11042221
    Abstract: 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.

  • Patent number: 11029757
    Abstract: A wearable device (such as a glove or other control adapted to be worn on a portion of a body) includes multiple magnetic field generators at various locations on the wearable device and a magnetic flux sensor at a predetermined position relative to the wearable device. A position determines spatial positions of locations of the wearable device based on magnetic fields generated by various magnetic field generators and detected by the magnetic flux sensor. In some embodiments, the magnetic field generators have known positions relative to each other. Additionally, each magnetic field generator may generate a magnetic field in response to an input signal having a particular attribute, allowing the magnetic flux sensor to identify magnetic fields generated by different magnetic field generators.

  • Patent number: 11015926
    Abstract: A deformation sensing apparatus comprises a transmitter coupled to a propagation channel, and a receiver coupled to the same first end of the propagation channel. The propagation channel of the deformation is a transmission line, where a signal is transmitted by the transmitter and reflected signals are measured by the receiver responsive to the transmitted signals. A bend in the propagation channel results in a change in impedance of the transmission line at a location of the bend, resulting in a reflection of the signal from the location of the bend. The time delay of the reflected signals corresponds to the distance along the length of the channel where a bending of the propagation channel occurs. The amplitude of the reflected signal corresponds to a bend angle.

  • Patent number: 10989330
    Abstract: 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.

  • Patent number: 10976826
    Abstract: A virtual reality system including a garment worn by a user, such as a glove, includes a jamming that jams movement of a portion of the user's body by increasing a rigidity of certain portions of the garment or by preventing a certain portion of the garment from expanding past a certain length. This allows the garment to simulate the physical sensation that occurs when the user touches an object. For example, to simulate the sensation of holding a coffee mug, the jamming mechanism prevents the user's fingers from curling after the user's fingers have reached a position equivalent to making physical contact with the coffee mug.

  • Patent number: 10866035
    Abstract: A wearable heat transfer device provides a user with haptic feedback providing sensations of hot or cold. The wearable heat transfer device comprises a heat source/sink and a programmable interface having heat transfer characteristics that are modified based on a signal received by the programmable interface. For example, a thickness of the programmable interface changes based on the received signal, altering heat transfer by the programmable interface. In another example, an electric field is applied to the programmable interface, changing one or more properties of the programmable interface affecting heat transfer.

  • Patent number: 10817049
    Abstract: 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.

  • Patent number: 10818433
    Abstract: Dielectric ceramic particulates are introduced into thin a sheet of pre-cured elastomer to form a sheet. Successive layers of the sheets may then be laminated together to form a finished article. An electric field may be applied to the article during a curing process while the article is at a temperature near a Curie temperature of the dielectric ceramic particulates to increase a dielectric constant of the article. As each sheet may be different from each other in the finished article, the resulting finished article may have anisotropic dielectric and mechanical properties. Similarly, tiled dielectric ceramic structures may be introduced into the elastomers layers to generate materials with varying dielectric constants.

  • Publication number: 20200249762
    Abstract: 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.
