In this paper, we proposed to develop a step counter system with high accuracy in comparison with the commercial applications. The proposed system is using the inertial measurement unit MPU9250 which consists of 3-DOF gyroscope and 3-DOF accelerometer; these sensors were calibrated carefully to avoid drift error. Furthermore, nRF24L01 wireless data transmitter/receiver is integrated for added convenience for users. After preprocessing, the recorded data are extracted from this IMU will be combined with step detection algorithm to find out the number of steps. The proposed algorithm was tested carefully with promising results of 96.5% in accuracy. date: 2017-10-05 date_type: published official_url: http://icdv.uet.vnu.edu.vn/ full_text_status: public pres_type: lecture pagerange: 69-74 event_title: The 7th International Conference on Integrated Circuits, Design, and Verification (ICDV 2017) event_location: Ha noi, Viet nam event_dates: 5-6, Oct, 2017 event_type: conference refereed: TRUE citation: Pham, Van Thanh and Nguyen, Thi Anh Dao and Tran, Thi Thuy Quynh and Chu, Thi Phuong Dung and Tran, Duc Tan (2017) A Novel Step Counter Supporting For Indoor Positioning Based On Inertial Measurement Unit.
