How to Design Elevator Door Re-Opening/Closing Button which can be Easily Distinguished

Abstract

The main purposes of this study are to propose a design of the re-opening/closing elevator buttons that can be easily distinguished from each other and to evaluate the effect of the easiness of distinction between these buttons. We conducted three different experiments. We divided the design of the elevator buttons into five elements: Illustration, Base color, Illustration color, Width of re-opening button and Ruby. The first experiment to evaluate the effect of the easiness of illustrations to distinguish re-opening button from the closing button showed that the illustration based on Face distinguished the re-opening button from the closing button most easily. The second experiment to evaluate the effect of the easiness of distinction in each element showed that illustrations based on Face （illustration）, White （base color） and 1.25 times width distinguished the re-opening button from the closing button easily. The third experiment to evaluate the effect of the elements that were found to make the re-opening/closing buttons more distinguishable showed that partial optimization of existing designs could reduce mistaking the re-opening button for the closing button. In conclusion, we proposed a design of the re-opening/closing elevator buttons that can be easily distinguished from each other, and we evaluated the easiness of distinction regarding five divided design elements.
