  • Patent number: 12353645
    Abstract: A tracking system and associated algorithms are disclosed that can provide a user with a continuous, reset-free augmented reality (AR) experience. When the user wears an AR headset equipped with a camera and an inertial measurement unit (IMU), motion sensor data from the IMU can be combined with image data from the camera to create a device pose, representing a position and an orientation of the headset relative to its environment. In some implementations, when a reset occurs, a six-degrees-of-freedom (6DoF) algorithm can be configured to support the pose until a re-initialization is completed. In some implementations, a neural network can be used to correct for IMU integration drifts in the 6DoF algorithm. In some implementations, the IMU-based 6DoF uses a neural network that exploits the device's past motion to infer its future motion.

  • Patent number: 12340012
    Abstract: An operation detection device includes a motion detection unit that detects a motion of an operator; a certainty level estimation unit; a sounds detection unit; and an operation determination unit. The certainty level estimation unit estimates a certainty level at predetermined time intervals based on the motion of the operator detected by the motion detection unit and acquires the certainty level with respect to a change in the motion. The certainty level indicates that the operator has performed a predetermined operation. The sound detection unit detects a predetermined sound generated from an operation object operated by the operator or an physical body accompanying the operation object when the predetermined operation is performed.

  • Patent number: 12315413
    Abstract: A display, system and method of providing a display are described. The display includes sets of microLEDs. Each set of microLEDs corresponds to one of a plurality of pixels of the display and produces a combination of light that forms a color of the corresponding one of the pixels. Lenses control an emission angle and emission profile of the light emitted by the sets of microLEDs. Each set of microLEDs has a red microLED that emits red light, a green microLED that emits green light, a blue microLED that emits blue light, and another microLED that emits light along a red-green locus.
