Rotation of visual content on a display unit
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.
