1. A device for improving readability of content displayed to a viewer, comprising:
a screen for displaying the content to the viewer,
a motion sensor for measuring a displacement of the device and
an eye tracker for measuring a change in gaze of the viewer when gazing at the screen,
the device comprising at least one processor being configured to,
determine that the change in gaze and the displacement of the device are out-of-sync by operations comprising:
deriving a phase difference between the measured change in gaze and the measured displacement of the device, and
determining that the change in gaze and the displacement of the device are out-of-sync if the derived phase difference exceeds a threshold value, and
in response to determining that the change in gaze and the displacement of the device are out-of-sync, adjust the displayed content so as to improve the readability of the displayed content.
