| summary |
This study evaluated architectural space quantitatively based on ambulatory vision. In this paper, we propose a computational analysis method of a visual space along a walking path by using a virtual reality display. A display image of our system is shown from the first-person perspective. We consider the perspective to be the visual field of the users. To convert the perspective into a visual field, we take advantage of depth buffer data, which can specify how far a pixel of an object is on the perspective. To analyse a visual space by a sequence of visual field, we quantify the geometric characteristics based on isovist theory. A virtual reality display, which employs a wide range view angle and a head-tracking system, also enables us to analyse the relation between the visual field and head motion. |
