We present PaperTab, a paper computer with multiple 10.7” functional touch sensitive flexible electrophoretic displays. PaperTab merges the benefits of working with electronic documents with the tangibility of paper documents. In PaperTab, each document window is represented as a physical, functional, flexible e-paper screen called a displaywindow. Each displaywindow is an Android computer that can show documents at varying resolutions. The location of displaywindows is tracked on the desk using an electro-magnetic tracker. This allows for context-aware operations between displaywindows. Touch and bend sensors in each displaywindow allow users to navigate content.
