Intelligent services development for home devices

Context-aware computer systems are a new generation of computer systems which behavior is tailored to best suit the environment they are located. The goal of the research is to develop a system with clearly defined application programming interface (API) to deduce various parameters of the context and to publish expertise to applications of interest. System would provide means to count people in a given area and detect their positions, to detect current speaker position, to estimate user attention to an object by face detection and to acquire data about position and orientation of different objects in space. For these purposes sensing devices such as 3D camera, optical camera, microphone array and accelerometer would be utilized. System would also provide estimation of current user activities and overall user busyness (interruptibility) inside a room. Within the research the system would be applied for: (1) setting working profile of an application depending on the context; (2) energy saving to automatically control light depending on user activity; (3) new user interfaces based on gesture recognition to issue commands to the system. Application of the solution is viable through the cooperation with NIT company from Novi Sad, which has been successfully cooperating with set-top box (TV) manufacturers (Vestel), home control equipment manufacturers (Control4), light control equipment manufacturers (Atmel).
