1. A system, comprising:
- A rear camera of a mobile device configured to capture at least one frame that includes a face of a user;
a database configured to store the at least one frame;
a processor communicatively coupled to the rear camera and the database, the processor configured to;
detect the face in the captured at least one frame;
extract a left eye image and a right eye image of the face from the at least one frame;
resize the left eye image to a size matching one of a calibrated set of left eye images for the user and the right eye image to a size matching one of a calibrated set of right eye images for the user;
compare the resized left eye image to the calibrated set of left eye images for the user, wherein each image in the calibrated set of left eye images corresponds to a known eye gaze direction for a left eye of the user;
compare the resized right eye image to the calibrated set of right eye images for the user, wherein each image in the calibrated set of right eye images corresponds to a known eye gaze direction for a right eye of the user;
determine a direction of eye gaze based upon the comparison of the resized left eye image to the calibrated set of images for the left eye and the comparison of the resized right eye image to the calibrated set of images for the right eye;
identify, based upon the determination of the direction of eye gaze and a known configuration of an eye gaze board having a plurality of quadrants, a quadrant of the eye gaze board corresponding to the direction of eye gaze, wherein each of the plurality of quadrants of the eye gaze board comprise at least one character; and
display the at least one character from the quadrant as a part of a text-based message.

Abstract
Techniques for text entry using gestures are disclosed. As disclosed, a camera may capture a frame and the face of the user can be detected therein. Landmarks can be aligned to the face in the captured frame. A left eye image and a right eye image may be extracted from the captured frame. The left eye image and the right image each may be resized and compared to a calibration template. A direction of eye gaze may be determined based upon the comparison. A character or word may be predicted based upon the determination of the direction of eye gaze and a known configuration of an eye gaze board (e.g., an E-tran board). The predicted character or word can be included as a part of a text-based message.

11. A computer-implemented method, comprising:
-
capturing, by a rear camera of a mobile device, at least one frame that includes a face of a user; detecting the face in the captured at least one frame; extracting a left eye image and a right eye image of the face from the at least one frame; resizing the left eye image to a size matching one of a calibrated set of left eye images for the user and the right eye image to a size matching one of a calibrated set of right eye images for the user; comparing the resized left eye image to the calibrated set of left eye images for the user, wherein each image in the calibrated set of left eye images corresponds to a known eye gaze direction for a left eye of the user; comparing the resized right eye image to the calibrated set of right eye images for the user, wherein each image in the calibrated set of right eye images corresponds to a known eye gaze direction for a right eye of the user; determining a direction of eye gaze based upon the comparison of the resized left eye image to the calibrated set of images for the left eye and the comparison of the resized right eye image to the calibrated set of images for the right eye; identifying, based upon the determination of the direction of eye gaze and a known configuration of an eye gaze board having a plurality of quadrants, a quadrant of eye gaze board corresponding to the direction of eye gaze, wherein each of the plurality of quadrants of the eye gaze board comprise at least one character; and displaying the at least one character from the quadrant as a part of a text-based message. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer readable medium having stored thereon computer readable instructions that are executable to cause one or more processors to perform operations, comprising:
-
capturing, by a rear camera of a mobile device, at least one frame that includes a face of a user; detecting the face in the captured at least one frame; extract a left eye image and a right eye image of the face from the at least one frame; resizing the left eye image to a size matching one of a calibrated set of left eye images for the user and the right eye image to a size matching one of a calibrated set of right eye images for the user; comparing the resized left eye image to the calibrated set of left eye images for the user, wherein each image in the calibrated set of left eye images corresponds to a known eye gaze direction for a left eye of the user; comparing the resized right eye image to the calibrated set of right eye images for the user, wherein each image in the calibrated set of right eye images corresponds to a known eye gaze direction for a right eye of the user; determining a direction of eye gaze based upon the comparison of the resized left eye image to the calibrated set of images for the left eye and the comparison of the resized right eye image to the calibrated set of images for the right eye; identifying, based upon the determination of the direction of eye gaze and a known configuration of an eye gaze board having a plurality of quadrants, a quadrant of the eye gaze board corresponding to the direction of eye gaze, wherein each of the plurality of quadrants of the eye gaze board comprise at least one character; and displaying the at least one character from the quadrant as a part of a text-based message.
