THE PEN WONDER: The computer pen, or digital pen, is a computer invention that writes on paper and transmits the writing into digital media. Although touch screen devices represent a movement away from paper, approximately eighty-percent of businesses still use paper based forms. Many professions hand-write their notes, tables, diagrams and drawings instead of using tablets or other devices. The computer pen is comparable to a regular ink pen (even uses refillable ink) that writes on regular paper, except it has an optical reader that records motion, images and coordinates. The recorded data is then transmitted to a computer via a wireless transmitter. You can browse and edit your written notes, diagrams, tables, or drawings. A useful feature of this computer invention is that hand-written digital files can be easily converted into text fonts for use in word documents or emails. Digital pen technology was first developed by the Swedish inventor and entrepreneur Christer Fåhraues.
