摘要：A notebook computer is upgraded by providing stylus-cooperating indicia near the keyboard and an optical stylus that can recognize the indicia. The indicia includes a
sketch pad area that cooperates with the optical stylus to transmit movement data to the computer. The movement data is relative in position and absolute in orientation, providing ΔX and ΔY in the sketch pad's coordinate plane rather than the stylus's. Other indicia represents tool buttons recognized by both humans and the stylus. A stylus and stickers kits is used to upgraded existing notebook computers. New ones can be manufactured with the stylus-cooperating indicia in place or the indicia may be provided on a substrate that may be attached to any notebook computer, as selected and positioned by the end user. The stickers or substrate is thin enough to permit the notebook computer to be closed as usual. In an alternative embodiment, the indicia is printed on a mouse pad or other surface to provide tablet and stylus functionality to other kinds of personal computers as well.
