FRAME TRACKING SYSTEM FOR A HEAD-MOUNTED DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240184357 titled 'FRAME TRACKING SYSTEM FOR A HEAD-MOUNTED DEVICE

Simplified Explanation

The abstract describes an eye tracking system for a head-mounted device that includes a light source, an image sensor, and a frame tracking system. The system can determine absolute and relative eye orientations, as well as the displacement of the device frame relative to the user's face. The frame tracking system includes position sensors on the frame and logic to determine displacement data.

• Light source, image sensor, and frame tracking system used for eye tracking
• Determines absolute and relative eye orientations
• Tracks displacement of head-mounted device frame relative to user's face
• Frame tracking system includes position sensors and logic for determining displacement data

Potential Applications

The technology can be used in virtual reality headsets, augmented reality glasses, medical devices for eye tracking, and assistive technologies for individuals with disabilities.

Problems Solved

The system solves the problem of frame slippage, jostling, or displacement of head-mounted devices, ensuring accurate eye tracking data even with movement.

Benefits

- Improved accuracy in eye tracking - Enhanced user experience in virtual and augmented reality applications - Increased accessibility for individuals with disabilities

Potential Commercial Applications

- Virtual reality gaming - Medical devices for eye tracking in healthcare - Assistive technologies for communication and control

Possible Prior Art

Prior art may include existing eye tracking systems for head-mounted devices, such as those used in virtual reality headsets and medical devices for eye tracking.

How does the system handle different lighting conditions?

The abstract does not mention how the eye tracking system adjusts for varying lighting environments to ensure accurate eye tracking data.

What is the accuracy of the system in tracking eye movements?

The abstract does not provide information on the precision or accuracy of the eye tracking system in capturing and interpreting eye movements.

Original Abstract Submitted

an apparatus, system, and method for an eye tracking system for a head-mounted device include a light source, an image sensor, and a frame tracking system. the light source and image sensor may be configured to determine absolute and relative eye orientations. the frame tracking system may be configured to determine the displacement of a head-mounted device frame relative to the face of the user. the frame tracking system may provide displacement data for the displacement of the head-mounted device frame to the eye tracking system to enable the eye tracking system to compensate for frame slippage, frame jostling, or other frame displacement (relative to the face of the user). the frame tracking system may include one or more position sensors disposed on the head-mounted device frame and logic configured to determine displacement data using information from the one or more position sensors.
