IGEL is a new shape modeling tool mimicking heat cutters for 3D computer graphics. Heat cutter os a tool fir processing styrene form. Since blades of cutters are steal wires, users can freely bend them. IGEL realizes this operation by a sketch input system. IGEL has two different modes, 2D and 3D modes, and users can switch them freely. In 2D mode, users can draw the shapes of cutters freely. In 3D mode, users can cut the styrene forms using their own cutters. Our implementation represents the styrene forms as triangular meshes, and cuts the meshes according to the user's operation. This paper describes the processing flow of IGEL, shows examples, and discusses our future works.

In this paper, we propose the wearable piano system using the conductive fabric, whose name is TextileNetPiano (TNP). The keyboards of TNP are made with the condutive fabric, and the number, size, and shape of the keyboard is flexible. It is detected whether the user touches the fabric keyboard using a touch sensor. Information which is detected is transmitted to the sound source system on the outside environment by a wireless communication, and it sounds. Our proposal means not only the improvement of the wearable piano system, but also a trial about new usage of the conductive fabric.

In this paper, we proposed WindStage which can record and reproduce of the wind patterns from many directions. Ordinary anemoscope and air speedometer such as fence-sitter are able to detect wind from only one direction of the wind. We developed WindCamera which can measure information about wind coming from many directions simultaneously and WindDisplay which can reproduce wind patterns in many directions. We explained WindStage which integrated WindCamera with WindDisplay and an application of WindStage.

Recently we have a lot of chances to see huge displays in towns for their great effect on publicity and advertisement. There exist the restrictions on both budget and setup in huge displays on buildings, and they often prevent huge displays from being used for single event or irregular base shape. Lighting control for lights arranged in line, for example illuminations in Christmas season, has the limit for appealing more power of expression. In this paper, we describe the design of LED display system with large degree of freedom in pixel arrangement, ease of setup, as well as its implementation and its expected applications. This system enables the users to implement dynamic representation with huge image displays, as well as applications for free-shaped walls, where we have no way to set up displays before.

We present a system that generates landscapes using a cocktail analogy. With this system, users generate landscapes by combining "ingredients." Users select a bottle containing the intended landscape element and pour an appropriate amount of water into a shaker. The amount of water used from each bottle determines the ratio of landscape elements. The relief of the surface and the position of each element are changed by shaking the shaker. This system provides the enjoyment of creating one's own favorite scenery.

We present new method for representing video sequences by using 3D computer graphics. The color intensity and hue of pixels is used to create another dimension for a 2D video sequence in order to generate 3D computer graphics. We have two media art works: “+1D” and “NeoCubism”, which are both used as an application for this method. "+1D" is an audience participation artwork which is combined with this method of 3D transformation on real-time video. "NeoCubism" is the combination of new media technologies with the traditional painting technique of Cubism. Either a panorama or a 360-degrees panoramic view of an object may be captured and represented on the screen in real-time. We have created a completely new artistic method for representing time-based images. Furthermore, "NeoCubism" allows one to depict a large amount of visual information simultaneously and in real-time.

In this study, we suggest the possibility of simulations as a form of content and propose a design for the operability of an exhibition that we researched and developed in cooperation with Enoshima Aquarium. It is thought that by combining in the same exhibit, an aquarium that recreates the natural ecosystem of the ocean with a computer running a simulation of that ecosystem, users can experience and understand information in ways they could not with each system separately. In this article, we detail the content design, operability design, user interface, structural layout, and technology behind the exhibit we created.

This paper presents a technique for visualization and interactive level-of-detail control of large number of time series data. The technique first generates clusters of time series values, then selects representative values for each cluster, and finally visualizes only representatives. The technique provides a simplified view without missing its interesting features since it reduces number of displaying polygonal lines by using a clustering algorithm. The technique also provides a user interface so that users can interactively select interesting representatives, and explore the time series values which belong to the clusters of the representatives. We applied the proposed technique to the visualization of air temperature in Japan. This paper introduces that we analyzed weather phenomena by using the proposed level-of-datail control and user interface.
