Abstract
A gaze tracking system, method, and computer product for tracking an eye gaze on a screen of a device including a single monocular camera, the system including measuring a rotation of a hinged plane of a display screen with respect to the eye gaze, combining the rotation with a three-dimensional movement of the camera, a position of the camera being constant with respect to the display screen, and estimating a point of gaze localization on the display screen using the single monocular camera as the input, in absence of a sensor, and without performing a display screen calibration.
Claims3
A gaze tracking system for tracking an eye gaze on a screen of a device including a single monocular camera, the system comprising:
- a processor, and
- a memory, the memory storing instructions to cause the processor to perform:
- measuring a rotation of a hinged plane of a display screen with respect to the eye gaze;
- combining the rotation with a three-dimensional movement of the camera, a position of the camera being constant with respect to the display screen;
- and
- estimating a point of gaze localization on the display screen using the single monocular camera as the input, in absence of a sensor, and without performing a display screen calibration.
A gaze tracking method for tracking an eye gaze on a screen of a device including a single monocular camera, the method comprising:
- measuring a rotation of a hinged plane of a display screen with respect to the eye gaze;
- combining the rotation with a three-dimensional movement of the camera, a position of the camera being constant with respect to the display screen;
- and
- estimating a point of gaze localization on the display screen using the single monocular camera as the input, in absence of a sensor, and without performing a display screen calibration.
A non-transitory computer-readable recording medium recording a gaze tracking program for tracking an eye gaze on a screen of a device including a single monocular camera, the program causing a computer to perform:
- measuring a rotation of a hinged plane of a display screen with respect to the eye gaze;
- combining the rotation with a three-dimensional movement of the camera, a position of the camera being constant with respect to the display screen;
- and
- estimating a point of gaze localization on the display screen using the single monocular camera as the input, in absence of a sensor, and without performing a display screen calibration.
