Vision is a form of remote sensing due to the fact that vision does not require physical contact with viewed objects. As a consequence, vision requires non-visual information for calibration of its system. Body movements in general and hand movement in particular generate the signals that are needed for calibration of vision. It is largely unknown how hand movements contribute to the calibration of vision.

In the real world it is difficult to manipulate the relationships between eye and hand positions and orientation in systematic ways. Virtual reality environments provide the necessary conditions to manipulate eye – hand relationships. Phantom object simulators in combination with head mounted displays and eye and head trackers are ideal tools to investigate calibration of the visual system. The postdoc is expected to initiate research and to collaborate within the virtual reality facility that is presently set up by the Helmholtz Institute.
