This study introduces a new system for fall detection and activity recognition using sensor data. The advanced Convolutional Neural Network (CNN) and eXtreme Gradient Boosting (XGB) model achieved 88% recall for accurate fall detection.

Area of Science:

  • Biomedical Engineering
  • Computer Science

Background:

  • Activity and fall detection are crucial for ambient assisted living systems.
  • Accurate human motion monitoring is essential for health monitoring and preventing fall-related injuries.

Purpose of the Study:

  • To develop a robust fall detection and activity recognition system.
  • To incorporate fall direction and severity into the detection process.
  • To improve upon existing methods for recognizing daily living activities and falls.

Main Methods:

  • Utilized Inertial Measurement Unit (IMU) data (accelerometer and gyroscope) from the SisFall dataset.
  • Processed data into 3-second non-overlapping segments with data augmentation.
  • Employed a Convolutional Neural Network (CNN) for feature extraction, followed by an eXtreme Gradient Boosting (XGB) classifier.
