What we can see is what we can touch. Though we unconsciously approach visible things, is it natural action? Which is the essential feature of existence, what we can touch or see ? In our art work visible and invisible lilliputs are muddling. We can see the visible lilliputs, but can not touch them. We can not see the invisible lilliputs but can touch them. They are living in the area where modalities of human senses are partly separated. Theme of this art work is “existence” of each modalities.

What will be affected if the scenery seen with a walk is replaced by the act of swimming? We propose a method of replacing various vision experiences accompanying such body movement by means of computer. Reference light is reflected with the reflector with which both arms were equipped, and the reflected light is observed with the CCD camera hung from the ceiling. Next, the motions of arms are analyzed by means of image processing, and then the speed of video is controlled in accordance with change of the motion. Therefore, an audience may feel swimming in the video. By experiencing the everyday scene through the operation "swimming", our work will offer to reconsider the gravity that has affected our action while it is unconscious, and the body itself.

This paper reports and discusses the first DiVA Exhibition organized by the Society for Art and Science, from May 20 to 23, 2003, at Tokyo Institute of Technology Oookayama Campus. All the awarded artworks are illustrated along with the commentaries of the authors and reviews. The project planning and management of this exhibition, the relationship between the sponsored society and the exhibition, and expectation for the future development are described. Also this paper discusses how to promote the collaboration between the scientists and artists.

A dragonfly is a familiar insect by which the sense of season can be shown. The expression of a dragonfly by CG can be expected as an element improving the sense of season in landscape simulation, virtual reality, etc. This paper proposes the flight model of a dragonfly based on aerodynamics. In this model, a dragonfly can be made to fly in real time considering the force caused by the flapping of the wings, performing flight characteristics including steep rise, sudden stop, hover and rapid turn. Furthermore, the flight route of a dragonfly can be easily established depending on the control-points placed in the space.

In the field of CAI, there are many systems for knowledge acquisition but few systems for skill acquisition, especially for some actual skills. Makeup is one of important actual skills for many people. Several makeup simulators have already been developed. The objective of these simulators is quality improvement of makeup simulation. In this paper, we propose a 3D makeup advice system that is able to advise a user about the real makeup on her/his face. In our system, the inputs are a distance data set and a color data set obtained from a 3D measurement equipment, and images with a digital camera. The outputs are the result of makeup simulation, instruction, and advice. An image of makeup simulation at each phase is displayed with explanations of makeup techniques. Advice is based on comparison of the simulation and the user′s real makeup. In an experiment of a prototype system, affirmative evaluation was obtained from most users.

This is new software for the editing and generating motion of human characters, which provides a useful and comprehensible environment for animators. We propose a new interface method for handling the whole body of a human character. This allows a user to drag a link an arbitrary position with any number of links pinned in a global frame and to be able to adjust motion of characters as a real-time operation, which can correct poses during playback. Inverse and forward kinematics is used for generating and optimizing motion. To make motion smooth, a relaxation parameter is introduced in motion dynamics calculation. A high speed collision detection algorithm is also proposed. Using this technique, it is very easy to make many series of derivative motions.
