Low-cost, single-antenna IoT devices with CSI measuring capabilities, are pervasive in today’s society. We show that it is possible to use inexpensive single-antenna Wi-Fi devices to monitor human eating habits.
SandDune is an infrastructure-based system that continuously monitors CSI information to detect the eating activity occurring in its vicinity. When it detects an eating activity, it scrutinizes the signals further to identify all hand-to-mouth eating gestures in the eating episode. A SandDune-like system can enable low cost, unobtrusive eating activity detection and monitoring with potential uses in health and well-being applications.
