摘要：Mobile devices are very popular electronic tools in modern life. Therefore researchers develop new services based on mobile device. The many fields of these services support 3-dimensional environment to enhance the feeling of reality. However input facilities equipped in mobile device have constraints to control the location of objects in space simulated by 2-dimensional screen. In this paper, we propose new input techniques to control the location of object in 3-dimensional space. Our method traces user’s touch and move action on touch screen, decodes actions, and translates into 3-dimensional coordinates. To trace user’s touch and move action, we use one or two fingers gestures. We implement sample Android application adopting our techniques. From our experience of using sample implementations, we can know that our input method can be effectively used to control the location of object in 3-dimensional space.
