It is thought that the interface using lower limbs is effective as a non-contact interface. Therefore, non-contact interfaces using lower limbs have been proposed in previous research. However, it is difficult to do complex inputs by using lower limbs. Here we focused on ﬁngers which could be moved skillfully. In this paper, we proposed a new non-contact intuitive interface by using multi-finger motions. The developed interface could detect the relative coordinates of the fingertip for the sheet by utilizing projective transformation, binarization and labeling. We applied it to the pointing device in non-contact state. This device was available for movement and a left-click and a right-click of the mouse pointer.
