Abstract
A method of real-time eye tracking feedback with an eye-movement tracking camera includes receiving a left eye movement transform, a right eye movement transform, and gaze direction information from a user's face and user's eyes. An eye tracking map is constructed including the left eye movement transform and the right eye movement transform. The eye tracking map is displayed with the left eye movement information, the right eye movement information, and the gaze direction information on a device screen. Feedback is provided to the user related the left eye movement transform, the right eye movement transform, and the gaze direction information.
Claims19
A method of real-time eye tracking feedback with an eye-movement tracking camera, the method comprising:
- receiving at least one or more of a left eye movement transform, a right eye movement transform, and gaze direction information from a user's face and user's eyes;
- constructing a focal point from the received at least one or more of a left eye movement transform, a right eye movement transform, and gaze direction information, wherein the focal point includes a calculated left eye position and a calculated right eye position;
- constructing an eye tracking map utilizing at least one or more of the left eye movement transform and the right eye movement transform, wherein the eye tracking map represents the position and movement of the left eye and the position and movement of the right eye, relative to the focal point, the eye tracking map including:
- at least one or more of left eye movement information, a left eye position relative to the eye tracking map, right eye movement information, and a right eye position relative to the eye tracking map;
- displaying the eye tracking map and the focal point information on a device including a device screen;
- and
- determining if the focal point is aligned with the eye tracking map:
- on condition the focal point and the eye tracking map are aligned:
- indicating to the user that the focal point is aligned with the eye tracking map;
- on condition the focal point and the eye tracking map are not aligned:
- providing feedback to the user related to at least one or more of the left eye movement transform, the right eye movement transform, and the gaze direction information, wherein the feedback alerts the user to a loss of alignment of the focal point to a position on the device screen.
A system for real-time eye tracking feedback with an eye-movement tracking camera comprising:
- an image sensor configured to receive at least one or more of a left eye movement transform, a right eye movement transform, and gaze direction information from a user's face and user's eyes;
- a processor;
- and
- a memory storing instructions that, when executed by the processor, configure the system to:
- receive, from the image sensor, at least one or more of the left eye movement transform, the right eye movement transform, and the gaze direction information from the user's face and the user's eyes;
- construct a focal point from the received at least one or more of a left eye movement transform, a right eye movement transform, and gaze direction information, wherein the focal point includes a calculated left eye position and a calculated right eye position;
- construct an eye tracking map utilizing at least one or more of the left eye movement transform and the right eye movement transform, wherein the eye tracking map represents the position and movement of the left eye and the position and movement of the right eye, relative to the focal point, the eye tracking map including:
- at least one or more of left eye movement information, a left eye position relative to the eye tracking map;
- right eye movement information;
- and a right eye position relative to the eye tracking map;
- display the eye tracking map and the focal point information on a device including a device screen;
- and
- determine if the focal point is aligned with the eye tracking map:
- on condition the focal point and the eye tracking map are aligned:
- indicate to the user that the focal point is aligned with the eye tracking map;
- on condition the focal point and the eye tracking map are not aligned:
- provide feedback to the user related to at least one or more of the left eye movement transform, the right eye movement transform, and the gaze direction information, wherein the feedback alerts the user to a loss of alignment of the focal point to a position on the device screen.
An apparatus comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, configure the apparatus to:
- receive at least one or more of a left eye movement transform, a right eye movement transform, and gaze direction information from a user's face and eyes;
- construct a focal point from the received at least one or more of a left eye movement transform, a right eye movement transform, and gaze direction information, wherein the focal point includes a calculated left eye position and a calculated right eye position;
- construct an eye tracking map utilizing at least one or more of the left eye movement transform, and the right eye movement transform, wherein the eye tracking map represents the position and movement of the left eye and the position and movement of the right eye, relative to the focal point, the eye tracking map including:
- at least one or more of left eye movement information, a left eye position relative to the eye tracking map, right eye movement information, and a right eye position relative to the eye tracking map;
- display the eye tracking map and the focal point information on a device including a device screen;
- and
- determine if the focal point is aligned with the eye tracking map:
- on condition the focal point and the eye tracking map are aligned:
- indicate to the user that the focal point is aligned with the eye tracking map;
- on condition the focal point and the eye tracking map are not aligned:
- provide feedback to the user related at least one or more of the left eye movement transform, the right eye movement transform, and the gaze direction information, wherein the feedback alerts the user to a loss of alignment of the focal point to a position on the device screen.
