TIMER-BASED EYE-TRACKING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240028116 titled 'TIMER-BASED EYE-TRACKING

Simplified Explanation

The present disclosure is about a method for eye-tracking using a MEMS scanner. The method involves scanning a beam over an eye to detect glints reflected from a scan region using multiple detectors. Each glint is associated with a plane that includes the location of its respective scanner and detector. The corneal center of the eye is identified by finding the intersection of these planes. The gaze vector of the eye is then determined based on the corneal center and the pupil center identified using pupillometry.

• The method uses a MEMS scanner to scan a beam over an eye.
• Glints reflected from the scan region are detected using multiple detectors.
• Each glint is associated with a plane that includes the location of its respective scanner and detector.
• The corneal center of the eye is identified by finding the intersection of these planes.
• The gaze vector of the eye is determined based on the corneal center and the pupil center identified using pupillometry.

Potential applications of this technology:

• Eye-tracking for human-computer interaction.
• Medical diagnostics and research.
• Virtual reality and gaming.
• Assistive technologies for individuals with disabilities.

Problems solved by this technology:

• Accurate and non-invasive eye-tracking.
• Improved precision and reliability in eye-tracking systems.
• Enhanced user experience in various applications.
• Better understanding of eye movements and behavior.

Benefits of this technology:

• Real-time and high-resolution eye-tracking.
• Reduced complexity and cost compared to traditional eye-tracking methods.
• Non-contact and non-invasive measurement.
• Improved accuracy and reliability in gaze estimation.

Original Abstract Submitted

the present disclosure is directed toward eye-tracking by scanning at least one scan beam over a scan region on an eye using a mems scanner at a first location, detecting a plurality of glints reflected from the scan region at a plurality of detectors, defining a plane for each glint that includes the location of its respective scanner and its respective detector, and identifying the corneal center of the eye based on the intersection of the plurality of planes. a gaze vector for the eye is then determined based on the corneal center and a pupil center identified using pupillometry.
