    This paper describes a head mounted display (HMD) system which can present realistic visual images of the environment. There are several types of commercial HMDs for virtual reality systems. One of the problems of their systems is that the screen size is small in order to keep the image resolution high. Therefore, the screen frame and displayed images overlap and impair the sense of reality. In or... View full abstract»

    A human uses both image and language to represent his own idea and to communicate with others. He may not be conscious of this fact, but images and words are translated to each other frequently in his brain when he is thinking. The functions of such translation and understanding are essential in constructing intelligent man-machine interfaces. It is also important to pick images and words in accor... View full abstract»

    Investigates the role emotions might play in robot design. It is argued that if one wants to deal with this problem one first has to develop a profound understanding of the mechanisms underlying behaviors which are called emotional. To investigate the relation between behavior and mechanism the “New Fungus Eater” approach is proposed, which is a minimalist bottom-up approach. It is sho... View full abstract»
