In this paper, we propose an interface in which a camera detects the finger depth, and images and buttons are zoomed in/out based on the information. To stabilize images during operation, an image before zooming is translated so that the displayed image does not move in case of the same zoom ratio. The zoom ratio is kept unchanged at the ratio more than a certain level so that the image is not further zoomed, which enables viewing the fully zoomed image stably or precise operation on the image. Multi-scale map viewer and zooming virtual keyboard were created as applications. We conducted a comparative experiment on the image stabilization method and confirmed superiority of the proposed method.
