Recently the miniaturization of mobile devices has progressed and such devices are difficult to have input interface that has wide operation area on their surface. Conventional input interface on a cell phone, such as a touch panel or keypad, has limited operation area. There has been many approaches to handle this problem, but they require users to wear some physical devices[Harrison and Hudson 2009] or to use in some specific environments[Roeber et al. 2003].
