Development and evaluation of History/Ecology Learning Support System applied local materials

我们开发了生态学习系统，并对其进行了评估。我们开发了位于我区、对我们友好的新集湖水生生物生态学习系统。构建了基于三维图形的水体模拟功能和基于XML语言的生态学习数据库访问功能。开发了适应用户层次的图片数据内容服务的用户界面，20名学生使用了该系统并进行了评价。结果，大多数用户对该系统感兴趣，并评价该系统对学习生态学有帮助。我们开发了历史学习系统并进行了评估。互联网提供的历史信息对游客来说不是很有趣，外国人也不能理解，因为还只有日本人写的。自从我们开发了这个系统来提供关于松江堡的3D和多语言信息，以及可以在松江堡周围的护城河上巡航的Horikawa Yuran的Hern故居。利用Java3D语言实现了三维图形，并通过场景图构建了三维虚拟世界。该场景图通过对象的树形结构来表示虚拟世界中的对象，并驱动游艇和公共汽车。用户可以通过带有GPS接收器的手机与服务器进行通信，并在那里获取历史信息。服务器具有地图数据库和历史信息数据库，接收用户手机上的图片数据并生成用户记录册。11名学生使用了该系统并对其进行了评估。他们评估3D和多语言信息是有效的。此外，有18名公众用户通过手机使用松江堡公园的功能。他们评估使用手机的功能是有效的。

We developed Ecology Learning System and evaluated it We developed Ecology Learning System for water and living things of Lake Shinji that located in our region and was friendly for ours. We constructed this system with the function of water simulation used 3D graphics and the function to access Ecology Learning database used XML language. And we developed the user interface that served contents of picture data that adapted to user's level.Twenty students used this system and evaluated it. As a result, almost users were interested in this system and evaluated that this system was useful for learning ecology.We developed Historical learning System and evaluated it too. Historical information served by Internet was not so interesting for tourists, and was not understandable for foreigners because of written by only Japanese yet. Since we developed the system to serve 3D and multi lingual information about Matsue Castle, and HERN old residence by HORIKAWA YURAN that could cruise in the moat around Matsue castle. We implemented 3D graphics by Java3D language, and constructed 3D virtual world by the scene graph. This scene graph represents object in virtual world by the tree construction for objects, and drives pleasure boat and bus. The user can communicate with the server by his/her cellular phone with GPS receiver and get historic information there. The server has map database and historic information database, receive picture data from user's cellular phone and produce user's record album.Eleven students used this system and evaluated it. They evaluated that 3D and multi lingual information were effective. Moreover, eighteen public users used functions by cellular phone at Matsue castle park. They evaluated that functions used cellular phone were effective.
