Grand challenge exemplar: Newpaper

Newpaper is a piece of incredibly smart electronic paper. It aims to:

• be better than real paper.
• be better than a current PDA + phone.
• be accessible to a wider proportion of the population -- because almost everyone's education has taught them to use paper, and these skills carry over to Newpaper.
• support all media in a uniform way. When you write on real paper with a pencil, you do not have to change the mode of the pencil when you switch from text to graphics. Newpaper will have the same property, but cover more media.
• support annotation.
• provide extra aids to both reading and composition. In particular Newpaper can prompt the reader with existing documents that appear to be relevant to what the user is reading or writing (like MIT's Remembrance Agents).
• support multi-media searching. (This continues the philosophy of supporting all media in a uniform way.)
• be usable in BBB (bus, bed, bath).
• support scanning in order to aid data capture, e.g. in the library.
• be such that the average user's document requirements can be totally satisfied by a small number of Newpapers, e.g. one, two or three.

In terms of design, Newpaper should offer `a clean sheet for HCI'. As a simple example, the way a document such as a map is presented will ensure the user is at the centre of the map.
