Abstract

Embodiments disclosed herein determine an optical parameter distribution at a projection surface. Embodiments of the system disclosed herein comprise a visual field sensor and a head orientation and/or position sensor. The visual field sensor is configured to measure a visual field of a user related to a specific vision task in a visual field of a user. The head orientation and/or position sensor is configured to measure head orientation and/or position of the user in relation to the visual field during the specific vision task. The system is configured to enable computation of the user's eye orientation in relation to the head of the user based on the gaze directions of the user and the head orientation and/or position of the user to determine an optical parameter distribution at a projection surface between the visual field and a retina of the user.
