Designing The Reading Experience For Scanned Multi-Lingual Picture Books On Mobile Phones

This paper reports on an adaption of the existing PopoutText and Clear Text display techniques to mobile phones. It explains the design rationale for a freely available iPhone application to read books from the International Children's Digital Library. Through a combination of applied image processing, a zoomable user interface, and a process of working with children to develop the detailed design, we present an interface that supports clear reading of scanned picture books in multiple languages on a mobile phone.
