The Penbook combines pen paper and digital.It takes hand-written
input using a digital pen on real paper that is augmented with
a projection screen and could easily redefine how we interact with documents. In this video you can see it at work in a medical records capacity.
The Penbook consists of a tablet computer (Motorola Zoom 2) that serves as the upright touch screen. It also uses a smartphone (Samsung Galaxy SII) connected to a laser pico projector (Microvision SHOWWX+ HDMI). This is to control the projected screen and its contents. There is also a Anoto pen, which allows hand-written input on paper without dispensing ink. The characters made with the pen are instead projected onto the paper.
