Detecting fall events from IMU accelerometer and gyroscope data in real time. Classifies motion patterns to distinguish genuine falls from normal activities like sitting down quickly, stumbling and recovering, or placing the device on a surface. Critical for elderly care wearables and workplace safety devices in construction or manufacturing. Models process short windows of 6-axis inertial data and trigger alerts within seconds of a fall event.
