Inkantatory paper: Interactive paper interface with multiple functional inks

There has been an increase in the number of solutions dealing withintegrating paper and digital information. For the input method, the Anotopen enables us to capture handwritten content as digital information. For the display method on paper, there are two approaches: (1) projecting visible light and (2) controlling colors of chromic inks. The authors focus on the latter approach since it candynamically display information on paper in print-like color. Hand-rewriting [Hashida et al. 2012] realized automatic rewrite processing on paper corresponding to handwriting using regular pen and paper. It utilizes a laser-based heating system to erase handwritten characters with bistable thermochromic ink. However, this means that it works just on a special desk equipped with the laser system.
