||We extend regular eyeglasses with multi-modal sensing and processing functions for context awareness. Our aim was to leverage eyeglasses as a platform to acquire and process context information according to the wearer's needs. The eyeglasses provide inertial motion, environmental light, and pulse sensors, data processing and wireless functionality, besides a rechargeable battery. We implemented prototypes of the smart eyeglasses and evaluated recognition performance in a study of daily activities with nine participants. The accuracy of recognising nine activity clusters from the smart eyeglasses motion sensors was 77% on average, confirming the benefit of smart eyeglasses for context-aware applications.
