3D holographic virtual object display controlling method based on human-eye tracking

A display controlling apparatus based on human-eye tracking, wherein the display controlling apparatus comprises a non-transitory program storage medium and a processor, the non-transitory program storage medium stores a program executed by the processor to perform a method which comprises:

• activating tracking of human eyes of a user;
• tracking motions of eyeballs of the user;
• controlling a 3D holographic virtual object presented in a display interface to rotate in response to the motions of the eyeballs of the user;
• and
• ending up the tracking of the human eyes of the user;
• wherein the step of tracking motions of eyeballs of the user in the method performed by the processor, comprises:
• acquiring a human-face image of the user;
• identifying human-eye regions on the human-face image;
• identifying a sclerotic region and an iris region in each of the human-eye regions according to the color contrast;
• and
• tracking eyeball motions of the user according to changes in position of the iris region relative to the human-eye region;
• wherein the step of identifying a sclerotic region and an iris region in each of the human-eye regions according to the color contrast, further comprises:
• determining a center connection line of centers of the iris region of the left eye and the iris region of the right eye of the user;
• the step of controlling a 3D holographic virtual object presented in a display interface to rotate in response to the motions of the eyeballs of the user comprises:
• rotating the 3D holographic virtual object about a rotation axis that is located at a barycenter of the 3D holographic virtual object and perpendicular to the center connection line.
