  • Patent number: 10634824
    Abstract: A liquid lens structure has an adjustable and continuous range of optical power. The liquid lens structure comprises a substrate layer and a deformable membrane which enclose a volume of liquid. The substrate layer is at least partially transparent in the optical band. The deformable membrane comprises a ground layer, two membrane layers, and two conductive layers. Each of the two conductive layers control electrical voltage applied to one of the membrane layers in reference to the ground layer, wherein each membrane layer deforms in response to applied electrical voltage. The deformation of the two membrane layers adjusts a curvature of the deformable membrane which provides the adjustable continuous range of optical power to the liquid lens structure.

  • Patent number: 10599217
    Abstract: A wearable device to be worn on a body part includes deformation sensors and a controller. The controller instructs the deformation sensors to measure deformation forces. The controller determines a position of the body part based on the measured deformation forces and a transfer function that maps deformation forces to positions of a same or corresponding body part. The transfer function is generated based on measurements from calibration and deformation sensors to sense corresponding positions of the body part and deformation forces. A calibration sensor may include a magnetic field generator and a magnetic flux sensor. The wearable device may be a glove and the body part may be a hand.

  • Patent number: 10591933
    Abstract: 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.

  • Patent number: 10585479
    Abstract: A control for a virtual reality (VR) system environment includes a portion and an additional portion each configured to contact different portions of a user's body. As one of the portions of the user's body moves towards the other potion of the user's body, the corresponding portion of the material contacting the moving portion of the user's body also moves towards the other portion of the material contacting the other portion of the user's body. Different positions of the portion and the additional portion relative to each other may correspond to different instructions that cause the VR system environment to perform different actions. In some embodiments, the control includes one or more feedback mechanisms providing the user with tactile feedback that simulates interactions with one or more virtual objects presented by the VR system environment.

  • Patent number: 10558036
    Abstract: A virtual reality (VR) headset includes an electronic display element that outputs image light via a plurality of sub-pixels that are separated from each other by a dark space. To mask the dark space between adjacent sub-pixels in the electronic display element, an optics block (e.g., a lens) in the VR headset oscillates or the electronic display element oscillates. For example, a piezoelectric material is coupled to the electronic display element or to the optics block. When a voltage is applied to the piezoelectric material, vibration of the piezoelectric material causes oscillation of the electronic display element or the optics block. The oscillation generates blur spots in the image light that mask the dark space between adjacent sub-pixels, with each blur spot corresponding to a blurred image of a sub-pixel in the image light.

    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: 10528138
    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.
