This “universal pen,†as Wang calls it, could transform the way people interact with computers. Unlike gizmos that write on computer displays or special pads of paper, Wang’s invention uses regular ink, works with regular paper, and lets users combine handwritten text and diagrams with digital content from reports, magazines, and Web pages. An executive on a plane trip, for instance, could mark up a paper copy of a report and later transfer the changes to the file on his or her computer automatically. [MIT Tech Review]
