Elevator Design Conforming to Universal Design

We have been developing elevator designs from this standpoint: "UNIVERAL DESIGN of elevator products is a design that can be used by as many people as possible regardless of their abilities." In a joint study with a research institute, we conducted a questionnaire survey and a video tape analysis to find out how elevators are actually used by wheelchair users and the visually impaired. Also, we reviewed associated global regional codes, including ADAAG of the USA and EN-81 of Europe. From these studies we propose what the best UNIVERSAL DESIGN for elevator users should be like.
