Abstract

A graphics presentation apparatus including a display unit, an eye-tracking module, and a data output module. The eye-tracking module registers image data representing at least one eye of a user of the apparatus. Furthermore, the eye-tracking module determines, based on the registered image data, an orientation of the at least one eye relative to the display unit. Finally, in response thereto, the eye-tracking module generates a control signal controlling the data output module to produce visual content with such orientation on the display unit that a misalignment between the orientation of said at least one part and the orientation of the at least one eye of the user is minimized.

Claims

1. A non-transitory machine readable medium having instructions stored thereon for controlling an eye tracking device, wherein the instructions are executable by one or more processors to at least:

determine a frame of reference;

determine, for content displayed on a display device, a content angle relative to the frame of reference; and

activate a passive or deactivated eye tracking device upon the display device being oriented such that the content angle exceeds a threshold angle relative to the frame of reference.
