Walking Through Apertures with Field of View Restriction

This study investigates the effect of both horizontal and vertical field of view restriction on walking through apertures. Speed, angle of passage, the range of shoulder rotation and clearance of the aperture were used as measures. The hypothesis was that field of view restriction would increase the rotational angle by which participants passed through apertures because the perception affordance between them and the aperture would change. No effects were found on shoulder rotation nor an effect of horizontal field of view restriction was found. However, when the visible visual angle in the vertical plane decreased, walking speed decreased. Meaning that confidence is lost when the vertical Field of View is restricted, but not when the horizontal Field of View is restricted. This leads to speculation when and how people judge aperture passability. Furthermore, shows this study more evidence for affordances and an understanding as to how people pass through apertures.
