<p>PROBLEM TO BE SOLVED: To naturally link a virtual document (such as characters or image data) realized inside a computer with an actually existent document such as paper slip or book. SOLUTION: When an operator performs office work while putting a book 102 on a desk 101, a camera 105 parallelly fetches the image information of documents into the computer. Besides, an image such as icon or cursor peculiar for the computer is projected on the desk 101 or the document 102 by a projector 105. Since the cursor can be displayed on the document 102 as well, even in the case of character string printed on the book 102 or icon projected by the projector 105, the user selects it by moving the cursor through a mouse 106 so that a command can be issued. A processing part 111 performs processing such as dictionary retrieval, data base retrieval or character string calculation corresponding to the applied command, and the provided result is projected by the projector 105.</p> |
