Presentation Transcript

  1. Tallinn University of TechnologyTallinn 2011 Physical Activity Recognition with Inertial Measurement Unit Sergei Ovsjanski

  2. Sensor and platform • IMU • Accelerometer ADXL 345 • Gyroscope IDG 3200 • Arduino development board • AVR ATmega1280

  3. What is done? • Accelerometer and gyroscope are set to work with arduino board through I2C bus • From Arduino data is sent to MATLAB via RS232 • Raw data is noisy, so Kalman filter is implemented • Data configured to be written to text files and ready for signal processing analysis

  4. Future plans • Make it wireless (Xbee) • Extract features • Mean • Standard Deviation • Energy • Correlation • ????? • Construct 10 datasets (patients?) • PRTools: The Matlab Toolbox for Pattern Recognition
