We have been serving public wireless Internet access MIAKO.NET in Kyoto based on IEEE802.11b wireless LAN technology. MIAKO.Net provides mobile Internet access with a fixed IP address and high-level security. MIAKO.NET is quite unique in its volunteerism. It is managed by a nonprofit organization and supported by citizens in Kyoto. We describe the basic policy of MIAKO.NET and the design and operational issues of the network.

Almost four decades passed after the discovery of solitons and infinite dimensional integrable systems. The theory of integrable systems has had great impact to wide area in physics and mathematics. An approach to numerical algorithms in terms of integrable systems is surveyed. Some integrable systems of Lax form describe continuous flows of efficient numerical algorithms, for example, the QR algorithm and the Jacobi algorithm. Discretizations of integrable systems in tau-function level enable us to formulate algorithms for computing continued fractions such as the qd algorithm and the discrete Schur flow. A new singular value decomposition (I-SVD) algorithm is designed by using a discrete integrable system defined by the Christoffel-Darboux identity for orthogonal polynomials.

Conventionally, Web pages have been recognized as documents described by HTML. Image data, such as photographs, logos, maps, illustrations, and decorated text, have been treated as sub-components of Web documents. However, we can alternatively recognize all Web pages as images on the screen. We use the term Web image to mean the result of rendering given HTML data. When a Web page is treated as a Web image, its HTML data is considered to be metadata which describes the Web image content. Taking such a viewpoint, we propose a new image-based hypermedia which we call continuous web. In our model, there is no distinction between Web images and other images such as photographs. Therefore, we have designed a new data element, the areal-hyperlink, for connecting various images on the Web. We refer to all images that have areal-hyperlinks as hyperimages. Regarding everything on the Web as images leads us to consider a new style of browsing and navigating. We use the term scape-oriented browsing. We define a scape as a collection of continuously accumulated images. For example, whenever we walk in the real world, we can perceive and remember various forms of information through a scape process. Here, we describe new methods for scape-oriented browsing, such as see-through anchors, parallel navigation, and peripheral scape presentation. We have designed and implemented a prototype system based on our model. Our system offers continuous browsing and navigation to users. We explain our concepts and discuss the effectiveness and potential of this approach.

To realize a symbiotic relationship between humans and computers, it is crucial to estimate the external and internal state of the human by observation. One promising approach is to acquire the same visual information as the human acquires. We introduce our wearable vision sensor, which is equipped with a pair of active stereo cameras and a gaze-direction detector. From the visual information obtained by the wearable vision sensor, we present three basic three functionalities: 3D gaze point detection and image retrieval, 3D digitization of a hand-held object, and the measurement of a walking trajectory.

In the recent optimization world, mathematical programs with equilibrium constraints (MPECs) have been receiving much attention and there have been proposed a number of methods for solving MPECs. We provide a brief review of the recent achievements in the MPEC field and, as further applications of MPECs, we also mention the developments of the stochastic mathematical programs with equilibrium constraints (SMPECs).

Communityware is for more diverse and amorphous groups of people. Compared to current groupware studies, communityware focuses on an earlier stage of collaboration: group formation from a wide variety of people. We have been working on real scale experiments on communityware for more than 8 years. This paper summarizes our experiences on real scale experiments on communityware: the Mobile Assistant Project, Digital City Kyoto, and the Intercultural Collaboration Experiment.

It becomes possible to acquire information from diverse information sources of different media types. For instance, with the spreading of digital TV broadcasting and broadband Internet, it becomes possible for users to acquire more media-rich and more comprehensive contents by integrating Web contents and TV-program contents. Integration or fusion of contents from these multiple information sources requires more effective ways of comparing, complementing and composing those diverse information. A notable difference between Web contents and TV program contents is a way of viewing information. Conventional Web browsing is basically based on active viewing of information. That is, users are required to behave actively in order to access information. On the other hand, conventional TV broadcasting offers a passive way of viewing information. In order to integrate of Web contents and TV broadcast contents, not only contents themselves but also the difference of the viewing methods should be considered. This paper summarizes our research activities that aim at exploring technologies for "content integration from Web and broadcast information sources". Our research results are summarized into the following: content transformation between Web and TV broadcasting contents (Web2TV, TV2Web), content synchronization among Web contents and TV broadcasting contents (CWB, WebTelop).

In recent years, many computer-based learning systems have been developed and practically utilized in real classrooms, due to the spread of computers and networks to schools. In order to make this infrastructure valuable, we have to discuss how computers can be useful for learning and creation to students. We are focusing on the utilization of histories of user operations, as the possibilities for building effective learning environment. We present the utilization schemes of histories for computer-based learning and creation systems. The first one is utilization of user operation histories for the dynamic problem extraction. We show the result of the analysis on the time interval between user actions and the system model based on the analysis. The second one is the visualization of user operations during creation process on SqueakToys. In order to provide the capability of focusing on interesting points of the creation process, we introduce the semantics layers of user operation events and illustrate the mechanism to handle them.

We describe a new type of iterative learning control (ILC) which seeks the desired input in an appropriate finite dimensional input subspace. The method achieves perfect tracking for a class of uncertain systems without using time derivative of tracking error signals in the learning law. Its effectiveness is demonstrated by experiments. In addition, an application of the ILC method to continuous-time model identification is shown.

Semantic Web is a challenging framework to make Web information machine readable or understandable, but it seems not enough to make human's requirements for collecting and utilizing information automatically. The Agent technology becomes hopeful approach to bridge the gap between humans and machines. Agents may be autonomous and intelligent entities that may travel among agents and human. They get the requirements from human or other agents, and offer an appropriate solution through consulting among them. The main difference between agent and ordinary software development is the issue of coordination, cooperation and learning. This issue is very important for utilizing the Web information. We attempt to give an overview and research challenges with respect to the combination of machine learning and agent technologies with semantic Web from the perspective of interaction as well as interoperability among agents and humans.
