This paper reports on an adaption of the existing PopoutText and ClearText 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.
The HCIL has a long, rich history of transforming the experience people have with new technologies. From understanding user needs, to developing and evaluating these technologies, the lab's faculty, staff, and students have been leading the way in HCI research and teaching.
