The outdoor experience game could help learner to learn the course knowledge by interact with real world learning activities. And inspired learners to learn self-interest and extended desire. We proposed the web-based outdoor experience game-based learning system which includes game-based learning environment and related course authoring tools. The gameplay learning behavior will be similar as treasure-hunt. We provided real time information of game through geographical visualization displaying by integrate the Geography Information System (GIS), Global Position System (GPS), wireless technology and UMPC/EeePC/Notebook platform. Not only learners could get current game mission situation and related learning results after finishing their game-based learning activities but course editors also could utilize the related course authoring easily to develop such kind of course content. We hope this game-based learning system could be more helpful and useful for learners/ course editors in learning/developing behavior in this kind of game-based learning environment.
