==GAZE DETECTION APPARATUS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18064084 titled 'GAZE DETECTION APPARATUS

==Simplified Explanation==

The abstract describes a gaze detection apparatus that uses eye images to determine the position at which a user is looking. It includes a gaze detection unit, an orientation detection unit, a calibration unit, and a correction unit.

* The gaze detection unit analyzes the eye image to determine the user's gaze position.
* The orientation detection unit analyzes the eye image to determine the user's head orientation.
* The calibration unit performs a calibration operation to reduce the detection error of the gaze position and acquires a correction value.
* The correction unit adjusts the correction value based on the current gaze position, head orientation during calibration, and current head orientation.

Potential applications of this technology:

* Assistive technology for individuals with limited mobility or communication abilities.
* Eye-tracking systems for virtual reality or gaming applications.
* Human-computer interaction interfaces for hands-free control.

Problems solved by this technology:

* Accurate detection of a user's gaze position, even with head movement or changes in head orientation.
* Reduction of detection errors to improve the precision of gaze tracking.

Benefits of this technology:

* Improved accuracy and precision in determining a user's gaze position.
* Enhanced usability and functionality of gaze-based interaction systems.
* Increased accessibility for individuals with disabilities.


==Original Abstract Submitted==

A gaze detection apparatus includes at least one memory and at least one processor which function as: a gaze detection unit configured to detect, based on an eye image in which an eye of a user is imaged, a gaze position which is a position at which the user looks; an orientation detection unit configured to detect a head orientation which is an orientation of a head of the user, based on the eye image; a calibration unit configured to acquire a first correction value for reducing a detection error of the gaze position by a predetermined calibration operation; and a correction unit configured to correct the first correction value, based on gaze information related to a current gaze position, a head orientation during the predetermined calibration operation, and a current head orientation.
