In this research, the design of stairs handrail, riser, and width were operated using CG, and the influence of stairs design to the evaluation of the whole space was the objective of analysis.
First, the preliminary experiment was conducted, the result of real space and CG experiment were compared, and the validity of CG experiment was verified.
Finally, 11 patterns of object CG to which four examples of handrail as the real space for model in this experiment, a riser, and width were varied. As a result from conducting an evaluation experiment and analyzing its quantity, the evaluation tendency over change of a stairs design was clarified.
