    `Teleoperation' (or telerobotics) technology has been attracting much attention due to remarkable development of computer and communication technology and also to the advent of `virtual reality'. However, it is still difficult to apply this technology to the tasks which need sophisticated human skills. And from the viewpoint of human factors there are also many problems to be solved in this resear... View full abstract»

    This paper treats a basic system which realizes a scaled manipulation environment. Tools for scaled manipulation are necessary when one manipulates an extremely large or small size target. In the case of manipulation without scaling, it is possible to let the slave-manipulators have the same configuration as the master-manipulators. But in the case of different scale, it is difficult to design the... View full abstract»

    The employment of virtual human models interacting with actors is often used in science fiction and fantasy movies with sophisticated, off-line, 3D rendering tools. During the making of the movie the interaction between actors and models is limited. Because, when the action is recorded the actor is always alone and the interacting model is super-imposed on the film using special re-impression tech... View full abstract»

    In this paper, we describe an interactive surgical simulation system by voxel manipulation in a virtual space. In this system, we can manipulate a 3D image on a computer screen as if we treated a 3D object in real world. In order to treat a 3D image provided as a 3D array with high level interaction and real time operation, we developed techniques such as fast representation of surface figure with...

    Rhythm and its synchronization are important to natural interaction between humans and computers. For rhythm synchronization, computers must be able to understand human rhythm. Most previous work on teaching computers to understand rhythm has used programmed prior knowledge. Methods with no assumptions required large computer resources. This paper presents a system that understands any rhythm patt... View full abstract»

    The depth perception produced by motion parallax in the peripheral vision was investigated. To examine the effects of head movements on the depth perception, two observational conditions were settled, observation with head movements and without them. In experiment 1, the stimuli which simulated the identical amounts of depth were presented at various eccentricities. The results showed that the per... View full abstract»

    In addition to visual display, tactual-feedback system will play an important role in interactive computer interface design. Though the human visual system is generally more sensitive than the tactual one, the visual system is more subject to optical illusions. In this study, we have conducted experiments to obtain visual and/or haptical sensitivity of recognition of virtual figure features, such ... View full abstract»

    A mouse was modified to add tactile and force display via a solenoid driving a small pin and an electromagnet. In a target selection task experiment, the addition of tactile and force information feedback reduced target selection times, as compared to using a conventional mouse. A more pronounced effect was observed on the clicking time. In order to compare different sensory modalities, an experim... View full abstract»

    Our concepts of biology, evolution and complexity are constrained by having observed only a single instance of life, life on Earth. A truly comparative biology is needed to extend these concepts. Because we can not observe life on other planets, we are left with the alternative of creating artificial life forms on Earth. I will discuss the approach of inoculating evolution by natural selection int... View full abstract»

    Building on earlier work on fuzzy modeling of facial expressions we consider the problem of reasoning about the transition between two facial expressions. To deal with this problem we propose a hybrid reasoning scheme combining generalized modus tollens and fuzzy backward reasoning. The approach is illustrated by an example, and we conclude with a discussion about possible applications to an intel... View full abstract»

    High-speed locomotion of walking robots has been studied. The most considered gaits are trot gait and pace gait. In trot gait, the diagonal legs are operated by turning the support legs. In pace gait, the right or left legs are operated by turning the support legs. High-speed walk is a variable gait. However, an efficient method for high-speed walk does not only consist of a variable gait, it also... View full abstract»
