In this paper, we propose a memory recollection and retrieval system using spatial log data in daily living which allows users to see behavior of the past, unconscious behavior and object-oriented behavior in the Intelligent Space. The proposed system consists of multiple camera devices and microphone and it utilizes various kinds of data; human identification, human motion, object instance, weather...
We propose a robust method of estimating head orientation based on HOG. The proposed method is able to estimate head orientation with a camera even though when a user is not facing the camera. With this method, a head orientation can be estimated precisely in all three axes: roll, yaw, pitch. Furthermore, a simple and robust user identification method is composed by using the results of the Approximate...
In this paper, we proposed a pointing interaction system which allows users to control devises in Intelligent Space by using hand pointing. This system consists of multiple camera devices and a pan-tilt projector. This system recognizes user's face, user's head orientation and a spot where user points with the camera devices. However, to achieve a real interaction, an intuitive feedback is required...
