In this chapter, the authors present a new writing device called data-embedding pen, where a single inkjet nozzle is attached to its pen tip. When writing a stroke, the nozzle produces an additional ink-dot sequence along the stroke. The ink-dot sequence can represent various meta-information, such as the writer’s ID, the writing date, and a certain URL. Since the embedded meta-information is placed on the paper, it can be extracted by scanning or photographing the paper. Accordingly, by the data-embedding pen, a physical paper conveys any digital information. In other words, handwriting by the data-embedding pen can be a new medium connecting the physical and cyber worlds.
Chapter Preview

Data embedding into papers has been done statically by a printer. For example, XEROX DataGlyph (Hecht, 1994) is a kind of digital watermarks and information is printed and embedded as a fine texture into font images or photographs. Universal character pattern (Uchida, Iwamura, Omachi, & Kise, 2006; Omachi, Iwamura, Uchida, & Kise, 2006; Uchida, Sakai, Iwamura, Omachi, & Kise, 2007) is also printed character where class information is embedded in various ways.
