The Tobii I-Series has a built-in tilt sensor that adjusts the screen orientation depending on if the device is used in resting or upright position. This tilt sensor only checks the orientation while the I-Series is in use. When you hibernate Windows (e.g. by using sleep on gaze, by manually hibernating or if the device shut down due to low battery or overheating) and change rotation before turning on the device again, the I-Series device will not recognize the change. To correct the screen orientation, change the device position and then bring it back to your preferred position. The screen will then correct the screen orientation if you have automatic rotation in the I-Series Control Center enabled.
