DEVICE PAIRING USING MACHINE-READABLE OPTICAL LABEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240221212 titled 'DEVICE PAIRING USING MACHINE-READABLE OPTICAL LABEL

Simplified Explanation:

This patent application describes a method for aligning coordinate systems between separate augmented reality devices. One device captures an image of a machine-readable code displayed on another device, which encodes pose data. The first device then decodes this data to determine the relative pose between the two devices.

  • First device accesses pose data from its visual inertial odometry system.
  • Camera of the first device captures an image of a machine-readable code on the display of the second device.
  • Second device encodes its pose data in the machine-readable code.
  • First device decodes the pose data from the code to determine the relative pose between the two devices.

Key Features and Innovation:

  • Alignment of coordinate systems between separate AR devices.
  • Use of machine-readable codes to encode and decode pose data.
  • Determination of relative pose based on data from visual inertial odometry systems.

Potential Applications:

  • Collaborative augmented reality experiences.
  • Industrial maintenance and repair tasks.
  • Multi-user gaming and entertainment applications.

Problems Solved:

  • Ensuring accurate alignment of coordinate systems between AR devices.
  • Facilitating seamless interaction and collaboration between users of different devices.

Benefits:

  • Improved accuracy in shared AR experiences.
  • Enhanced user collaboration and interaction.
  • Simplified setup and calibration processes for multi-device AR applications.

Commercial Applications:

Augmented reality software development, industrial maintenance and repair services, multi-user gaming platforms.

Questions about the Technology:

1. How does this method improve the user experience in collaborative AR applications? 2. What are the potential limitations or challenges in implementing this technology in real-world scenarios?


Original Abstract Submitted

a method for aligning coordinate systems from separate augmented reality (ar) devices is described. in one aspect, a first device accesses first pose data from a first visual inertial odometry (vio) system of the first device. a camera of the first device captures an image of a machine-readable code that is displayed on a display of a second device. the second device encodes the machine-readable code with second pose data from a second vio system of the second device. the first device decodes the second pose data from the machine-readable code, and determines a relative pose between the first device and the second device based on the first pose data and the second pose data.
