Abstract:
An imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer, wherein: the imaging device is switchable between at least an active mode and a ready mode; the imaging device is configured, in the active mode, to use active eye illumination, which enables tracking of a corneal reflection, and to provide eye tracking data which include eye position and eye orientation; and the imaging device is configured, in the ready mode, to reduce an illumination intensity from a value the illumination intensity has in the active mode.
