TypeTile: A keyboard system that decorates characters depending on the way of typing

Generally, people use a keyboards as an interface for text input. However, unlike handwritten characters, typed characters are identical no matter who types them. To create variations in the appearance of typed characters, we usually decorate characters by changing fonts. For example, we change the font size, font color and boldness of the characters and the spacing between characters. However, due to these decorations, people must handle a few input processes such as checking the select menu. To improve current conditions, some research suggests methods of applying the user's unconscious actions while typing to decorate characters, using a laptop with a built-in acceleration sensor or body-worn electronic equipment [Iwasaki et al. 2009][Wang et al. 2004][TypeTrace 2006].
