Abstract
There is a high possibility that the opening and closing doors do not follow how the public doors are. The reason is probably because many people use it for the first time. In a survey of some cases, the act of pulling while pressing is not consistent with recognition. This paper focuses on affordance, we derive the numerical value of conditions under which recognition and action match. On the bases that we have done, we aim to propose a door handle to reduce door opening or closing error mistakes.
