An automatic door is opened it detects person comes sensor, for example, infrared sensor. This kind of doors very useful because we need not touch in order open However, persons, difficult detected they detect object touching. In this paper, propose detection method which tells existence person. device consisted an sensor and vibration motor. put on tip motor close hand. And signal, runs. Then can through safety without any cares
