项目摘要

In this research we defined digital cities as a social information infrastructure that gathers and provides urban information through the Internet. We proposed the three layer architecture for digital cities, which consists of the information layer, the interface layer, and the interaction layer. We established Digital City Kyoto Experiment Forum, which includes several research institutes, local authorities, companies, and volunteers. The forum developed and maintained Digital City Kyoto Prototype. We have achieved the following research results through this activity.1. Information Sharing in Digital CitiesWe developed a system called GeoLink that integrates the Web and the geographical information system. In GeoLink the XY coordinates of the web pages are determined based on the postal addresses written in the pages, and more than 5000 web pages in Kyoto can be searched. We have also developed GeoLinkSQL, which is an SQL-like language that enables us to write a query that specifies geographical and hyperlink relations of web pages.2. Human Interface for Digital CitiesWe developed map-based user interface for GeoLink. This interface enables neighborhood search, category search, and keyword search. The search results, which are hyperlinks to the searched web pages, are superimposed as icons on a map image. We also developed 3D implementation of Shijo Shopping Street (Kyoto's most popular shopping street). We used 3DML and photos taken by digital cameras. This 3D Kyoto shares the information with GeoLink, and we can find neighbor web pages while walking through the 3D City.3. Social Interaction in Digital CitiesWe developed a digital bus tour for visitors to the digital city by combining a chat system and 3DML. The tour guide agent will lead chatting visitors through 3D space. This is a prototype of agents that support social interaction among users of digital cities.

在这项研究中，我们将数字城市定义为一种社会信息基础架构，通过互联网收集并提供城市信息。我们提出了数字城市的三层体系结构，该架构由信息层，接口层和相互作用层组成。我们建立了数字城市京都实验论坛，其中包括几家研究机构，地方当局，公司和志愿者。论坛开发并维护了数字城市京都原型。我们已经通过此活动实现了以下研究结果。1。数字城市中的信息共享开发了一个名为Geolink的系统，该系统将网络和地理信息系统集成。在Geolink中，网页的XY坐标是根据页面中编写的邮政地址确定的，可以搜索京都的5000多个网页。我们还开发了Geolinksql，这是一种类似于SQL的语言，使我们能够编写一个指定Web页面地理和超链接关系的查询。2。数字城市的人界面为Geolink开发了基于地图的用户界面。该接口可实现社区搜索，类别搜索和关键字搜索。搜索结果是与搜索网页的超链接的超链接，在地图图像上被叠加为图标。我们还开发了Shijo购物街（京都最受欢迎的购物街）的3D实施。我们使用了3DML和数码相机拍摄的照片。这3D京都与Geolink共享信息，我们可以在3d City行走时找到邻居网页3。数字城市中的社交互动通过组合聊天系统和3DML为数字城市的访问者开发了数字巴士之旅。导游特工将带领访客通过3D空间。这是支持数字城市用户之间社交互动的代理商的原型。
