Abstract
An electronic device has a case and a screen attached to the case. The screen indicates a cursor position. The electronic device further has an input device mounted to the case. The input device includes a curved surface for detecting an object disposed on the curved surface using a light path that transfers an image of the object to an optical sensor. The optical sensor detects the movement of the object across the curved surface and in response, the input device manipulates the cursor position.
