1. A device adapted to provide eye-tracking data by imaging at least one eye of a viewer, wherein:
- the device operates an imaging sensor in a ready, active, or idle mode;
the device identifies a user of the device;
the device selects, from a set of active sub-modes and based on the identity of the user, an active sub-mode associated with the identified user;
the device determines, based on a viewing condition of the identified user, a sub-profile from a set of sub-profiles that are associated with the identified user; and
the device transitions the imaging sensor from the ready or idle mode to the selected active sub-mode, wherein settings of the selected active sub-mode are based on the determined sub-profile.

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 to use active eye illumination in the active mode, which enables tracking of a corneal reflection; 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, and to provide eye-tracking data which include eye position but not eye orientation.

11. A method for providing eye-tracking data by imaging at least one eye of a viewer, wherein the method comprises:
-
operating an imaging sensor of a device in a ready, active, or idle mode; identifying a user of the device; based on the identity of the user, selecting an active sub-mode associated with the identified user; determining, based on a viewing condition of the identified user, a sub-profile from a set of sub-profiles that are associated with the identified user; and transitioning the imaging sensor from the ready or idle mode to the selected active sub-mode, wherein settings of the selected active sub-mode are based on the determined sub-profile. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
