Abstract
A stylus input device, a stylus input device with display, and a method for entering input into a computer system are provided. The stylus is preferably used as a pointer that points to a particular region on an electronic display, and one or more buttons on the stylus can be used to scroll, modify or select that region. The buttons can be programmed in various ways to perform different functions, or one button can be programmed to perform a sequence of functions. The tip of the stylus need not contact the display surface to either render the stylus position or to select the region of the display shown by the stylus curser. The input device and system thereby operates in a contactless and wireless environment to leave the display area unencumbered to viewers of the display screen, and to allow more than one stylus to concurrently operate upon the display. The tip of the stylus can also be configured to scan an image of optically contrasting information, such as a barcode, in a contactless and wireless environment.
