  • Head tracking correlated motion detection for spatial audio applications
    Patent number: 11950083
    Abstract: Embodiments are disclosed for head tracking state detection based on correlated motion of a source device and a headset communicatively coupled to the source device. In an embodiment, a method comprises: obtaining, using one or more processors of a source device, source device motion data from a source device and headset motion data from a headset; determining, using the one or more processors, correlation measures using the source device motion data and the headset motion data; updating, using the one or more processors, a motion tracking state based on the determined correlation measures; and initiating head pose tracking in accordance with the updated motion tracking state.

  • Method and system for electronic communication by persons with disabilities
    Patent number: 11237639
    Abstract: A method and system for detecting and using intentional gestures utilizing a six-axis inertial measurement unit (IMU) provides individuals with limited motor abilities the ability to control multiple devices. The system responds to small intentional gestures produced by any part of the user's body. Unlike existing game controllers and adapted mouse devices, the system has the ability to learn the unique kinematic characteristics of the user's gestures.
