These days, AR (Augmented Reality) is widely used in various fields. Interacting with AR objects that are superimposed on a real world environment, by working with watching the real space in which AR object exist, it is possible to operate directory. In the case of AR objects are positioned out of reach, using the extension method of arm, it is possible to operate. However, there are several problems such as reducing the flexibility and accuracy. Then, we propose the relative input method for quick operation can be accurately an AR object with grasping the touchpad with still looking at the real space in which AR object exist.
