Abstract (in Japanese) (See Japanese page) 
(in English) Recent technology advancement makes mobile terminals such as smartphones and car navigation systems small PCs with full of functions. The increasing number of functions designed to help user could produce a undesired problem; increasing complexity of the operation.
To solve the problem many research has been proposed to utilize context-aware technology, which could predict a user's preference based on past user-experiences in similar context. Mobile devices always have to know location as context information in order to predict next operation quickly. GPS function consume a lot of battery power.
In this paper we propose a method for getting context information with a few numbers of using GPS function. We show it is quite effective by evaluating the result of experiments.
