Louis Liu: FallPoint: Contactless Fall Detection with 4D Radar
FallPoint: Contactless Fall Detection with 4D Radar.
Louis Liu created FallPoint, a fall-detection approach using 4D millimetre-wave radar, point-cloud analysis and a recurrent neural network. Radar can monitor motion without recording an identifiable video image, creating an important design conversation around safety, low-light performance and privacy.
Innovation mindset: When monitoring is necessary, search for a sensing method that preserves more dignity while still identifying dangerous events.
Official project title: FallPoint: Fall Detection With 4D mmWave Radar Using PointNet and a Recurrent Neural Network (Robotics and Intelligent Machines).
