The first shortcoming is that the conventional pen-type data input device uses a digital drawing board or a trackpad as a working plane. Therefore, an additional desktop space is required to place the digital drawing board or a trackpad, causing the desktop space to become Quite crowded. The second disadvantage is that the stylus used in the conventional pen-type data input device and the intelligent information system must be connected by wires, which will make the desktop space appear cluttered.
