| Abstract(in English) | When evacuating from the building in case of disaster , if you can store the record of the evacuated route in smart phone, there is a possibility that it can be used for people who can’t be evacuated by the rescue them. From this point of view, author proposes that detecting the direction change and estimating the number of floors according to the number of landings that passed. For the measurement of the angle of bending, use is made of Game Rotation Vector Sensor which is structured so as not to cause errors due to “drift” and minute vibration of the smart phone.In this Sensor, since the error becomes large depending on the holding method of the smart phone, correction is added. And reduce the error by summing the turning degrees when passing through multiple landings. As a result, when put in breast pocket, the estimation error rate of the moving rank decreased 99.1% to 1.82%. |
