Because present methods for mobile service navigation are insufficient to guide users efficiently to the services they need, the authors have been investigating a task oriented menu, which enables users to search for mobile internet services not by category but by what they want to do. Construction of the task-oriented menu is based on a task ontology modeling method which supports descriptions of user activities, such as task execution and defeating obstacles encountered during the task. Since a prototype within a limited domain and task proved its efficiency for navigating novice users, this paper introduces the next step toward the realization of the task-oriented menu system. We have built task model of the mobile users which covered about 97% of the assumed situations of mobile internet services. Then we reorganized “contexts” in the model and designed a menu hierarchy from the view point of the task. We have linked the designed menu to the set of actual mobile internet service sites included in the i-mode service operated by NTT docomo, consists of 5016 services. Among them, 4817 services are properly connected to the menu. This paper introduces a real scale task-oriented menu system for mobile service navigation with some findings in the process of the prototyping.
