In this paper, we propose a method for selecting appropriate data based on personal information of mobile users to improve the success rate for requesting data in a ubiquitous computing environment. With this method, the output data is selected based on users? requirements. Then, a ubiquitous terminal that actually outputs the selected data is selected based on the facility and activity level of all terminals and the category of the selected data. As a result, our method can output effective data for mobile users in a ubiquitous computing environment where there are many types of data and ubiquitous terminals. Furthermore, we show the effectiveness of our method by a simulation experiment.
