Patent number: 10782789Abstract: An input device is provided that comprises a display component, a detector, and a controller. The display component displays an image. The detector detects a first motion and a second motion. In the first motion, a pointer is slid over a first operation screen that lies in an imaginary plane including at least part of a spatial image that is a virtual image of the image formed in space. In the second motion, the pointer is moved into a second operation screen that lies in the imaginary plane and is different from the first operation screen.
