Future Directions

  1. Explore more features that are related to FOG physiology to improve classification accuracy.
  2. Study the window length for FOG prediction. How long before the onset will IMU signals start to change?
  3. Explore more features that might predict FOG onset.
  4. For time series based FOG prediction, consider different algorithms, such as deep learning, to avoid feature extraction.
  5. Extend the USB cable (1000Hz) communication of the IMU modules to Bluetooth (100Hz). The low sample rate of Bluetooth protocol might affect algorithm performance.
