Abstract
In this paper, an acoustic and visual signal based context awareness system is proposed for a mobile application. The proposed system senses and determines, in real time, user contextual information, such as where the user is or what the user does, by processing signals from the microphone and the camera embedded in the mobile device. An initial implementation of the algorithms into a smart phone demonstrated effectiveness of the proposed system.
