PURPOSE: A location movement display system of an indoor wheelchair with a display to which an augmented reality is applied is provided to process movement information of the indoor wheelchair in a building which is impossible to receive a GPS signal, thereby finding a path and a location of the indoor wheelchair. CONSTITUTION: A storage unit(100) includes path information of a building inside and location information of an important facility. A camera unit(200) photographs and transmits the front image. A sensor unit(300) confirms a movement distance by connection with a driving unit of an electromotive wheelchair through a wheel sensor(310). The sensor unit is connected to a steering device of the electromotive wheelchair through an operation recognition sensor(320). The sensor unit includes a gyro sensor and an acceleration sensor, and confirms a direction state of the electromotive wheelchair. A control unit(400) finds a location of the electromotive wheelchair during driving in a building by using a movement distance and angle information inputted from the sensor unit. The control unit delivers a 3D image is about a building map and a current location of the electromotive wheelchair in a real front image to a display unit(500).
