DEVICE TRACKING WITH INTEGRATED ANGLE-OF-ARRIVAL DATA - A simplified explanation of the abstract

This abstract first appeared for US patent application 18035970 titled 'DEVICE TRACKING WITH INTEGRATED ANGLE-OF-ARRIVAL DATA

Simplified Explanation

The patent application describes a wearable device, such as a head-wearable display (HWD), that can determine its position using a combination of angle-of-arrival (AOA) data and inertial data. This data is fused together using techniques like stochastic estimation or machine learning to accurately identify the device's pose (position and orientation). The computer device associated with the HWD can then use this pose information to modify virtual reality or augmented reality content, providing an immersive experience for the user.

  • The wearable device uses AOA data and inertial data to determine its position.
  • Data integration techniques like stochastic estimation and machine learning are used to fuse the AOA and inertial data.
  • The computer device associated with the wearable device uses the fused data to identify the device's pose.
  • The identified pose is used to modify virtual reality or augmented reality content for an immersive user experience.

Potential Applications

  • Virtual reality gaming and entertainment
  • Augmented reality applications for training and education
  • Industrial applications for remote assistance and visualization

Problems Solved

  • Accurately determining the position and orientation of a wearable device
  • Providing a seamless and immersive user experience in virtual reality or augmented reality environments

Benefits

  • Improved accuracy in determining the pose of a wearable device
  • Enhanced user experience in virtual reality or augmented reality content
  • Increased potential for applications in various industries such as gaming, education, and remote assistance.


Original Abstract Submitted

A wearable device, such as a head-wearable display (HWD), identifies a device pose based on a combination of angle-of-arrival (AOA) data generated by, for example, an ultra-wideband (UWB) positioning module, and inertial data generated by an inertial measurement unit (IMU). The HWD fuses the AOA data with the inertial data using data integration techniques such as one or more of stochastic estimation (e.g., a Kalman filter), a machine learning model, and the like, or any combination thereof. A computer device associated with the HWD can employ the fused data to identify a pose of the HWD (e.g., a six degree of freedom (6 DoF) pose) and can use the identified pose to modify virtual reality or augmented reality content implemented by the computer device, thereby providing an immersive and enjoyable experience for a user.
