Photos: dual-screen concept notebook from ASUS

This is how ASUS describes the system:

"The dual panel offers a flexible working space in which users can adapt to suit their prevailing usage scenarios, for example adjusting the size of the virtual touchpad and keyboard.

Through hand gestures, handwriting recognition, and multi-touch, users are presented with a control surface that is both flexible and intuitive. Users can use the dual-panel concept in a myriad of usage scenarios, for example as a conventional notebook with multi-touch screens, a virtual keyboard and touchpad; a multimedia hub, in which both dual panels could combine to form a larger display for widescreen entertainment; or an e-book mode in which users can hold the dual panel concept notebook just like they would a conventional book while flipping pages through intuitive gestures or by touch.

These concepts aim to bring convenience to the user through technological innovations and user-centric design."
