Assignee: ACER INCORPORATED
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 9:
10. A 3D display, comprising:
an eye tracking device, which detects a first eye position and a second eye position of a user;
a processor, configured to:
determine a viewing angle of the user and a rotation angle of a head of the user according to the first eye position and the second eye position;
estimate a first reference position and a first midpoint position between a first eye and a second eye of the user based on the first eye position and the second eye position of the user;

obtain a second reference position, and estimate a difference between the first reference position and the second reference position, wherein obtaining the second reference position comprises:
obtaining a first historical reference position corresponding to the viewing angle of the user compliant with a predetermined condition last time in response to determining that the viewing angle of the user does not comply with the predetermined condition, and taking the first historical reference position as the second reference position;

correct the first midpoint position to a second midpoint position based on the rotation angle of the user and the difference; and
determine at least one first pixel adapted to project a light to the first eye of the user and at least one second pixel adapted to project a light to the second eye of the user, among a plurality of pixels of the 3D display, based on the second midpoint position.
