Gaze direction adjustment for video calls and meetings
In a typical video meeting, each of two persons has a computer or a portable electronic device, controlled by one or more processors executing software instructions. Each device has a screen and a video camera. Typically, B's camera will be positioned above B's screen. Video of B is transmitted across a communication system from B's camera to A's screen. Because B is looking at A's image on the screen, A will perceive B to be focused downward, not making eye contact. The present invention analyzes video frames for the orientations of B's head and focus, and uses image editing software tools to virtually correct the gaze direction of B's eye to be directed toward B's camera. A's gaze direction may be similarly adjusted simultaneously. The approach may also be used with 3 or more participants, e.g., in a video conference.
1. A method, comprising:
a) communicating through a user interface an instruction that a user should look at a camera that is connected to or built into an electronic device which includes a screen;
b) determining a first gaze direction of the user when the user is looking at the camera;
c) communicating through the user interface that the user should look at a point on the screen;
d) determining a second gaze direction of the user when the user is looking at the point;
e) calculating an angular difference between the first gaze direction and the second gaze direction.
2. The method of claim 1 , wherein the point on the screen is proximate to an eye in an image that is displayed on the screen.
