ISS Expedition Duration
October 2009 - May 2012
Previous ISS Missions
Passages was first operated on ISS Expedition 21/22.
The objectives of Passages include:
- demonstrating the possible decrease of the use of the "Eye-Height" strategy (altitude of one's line of gaze parallel to the ground) for estimating affordances (what we perceive when we look at objects) after long exposure to weightlessness;
- testing the possibility of using "virtual visual eye-height" (visual perception of the altitude of one's line of gaze parallel to the ground in a virtual environment) context to restore the Earth-adapted strategy in weightlessness;
- testing for effects of weightlessness on estimates of visual distance and perceived eye height used to calibrate physical dimensions in the visual field such as in determining the "passibility" of a doorway.
