Interaction with Computers Using Mobile Devices

We propose a new interaction way that uses mobile devices to input and output devices of computers. The idea is simple but powerful, because 1) mobile devices are popular, 2) people can use them easily, 3) people carry them at all times, 4) two displays one of which is a big display for a computer and another is a small display of a mobile device may make new interaction and visualization and 5) a user can store parts of public data in physically independent device, that is his/her mobile device. We expect that our idea may make psychological barrier lower than now so that users can access and modify all data around the world more easily. In this paper, we show an example application based the idea we propose and discuss its possibilities.
