A system for tracking a gaze of a user across a multi-display arrangement, the system comprising: a first display ; a first eye tracking device configured to determine a user's gaze direction while the user is gazing at the first display ; a second display ; a second eye tracking device configured to determine the user's gaze direction while the user is gazing at the second display ; and a processor configured to: determine that the user's gaze has moved away from the first display in a direction of the second display ; and in response to determining that the user's gaze has moved away from the first display in the direction of the second display the system is characterized in that the processor is further configured to: deactivate the first eye tracking device , wherein a deactivated eye tracking device is not fully powered and/or not actively attempting to detect and/or determine the gaze direction of a user; and activate the second eye tracking device , wherein an activated eye tracking device is fully powered and/or actively attempting to detect and/or determine the gaze direction of a user. a first display ; a first eye tracking device configured to determine a user's gaze direction while the user is gazing at the first display ; a second display ; a second eye tracking device configured to determine the user's gaze direction while the user is gazing at the second display ; and a processor configured to: determine that the user's gaze has moved away from the first display in a direction of the second display ; and in response to determining that the user's gaze has moved away from the first display in the direction of the second display the system is characterized in that the processor is further configured to: deactivate the first eye tracking device , wherein a deactivated eye tracking device is not fully powered and/or not actively attempting to detect and/or determine the gaze direction of a user; and activate the second eye tracking device , wherein an activated eye tracking device is fully powered and/or actively attempting to detect and/or determine the gaze direction of a user. determine that the user's gaze has moved away from the first display in a direction of the second display ; and in response to determining that the user's gaze has moved away from the first display in the direction of the second display the system is characterized in that the processor is further configured to: deactivate the first eye tracking device , wherein a deactivated eye tracking device is not fully powered and/or not actively attempting to detect and/or determine the gaze direction of a user; and activate the second eye tracking device , wherein an activated eye tracking device is fully powered and/or actively attempting to detect and/or determine the gaze direction of a user. deactivate the first eye tracking device , wherein a deactivated eye tracking device is not fully powered and/or not actively attempting to detect and/or determine the gaze direction of a user; and activate the second eye tracking device , wherein an activated eye tracking device is fully powered and/or actively attempting to detect and/or determine the gaze direction of a user. <EOS>
