Interaction Design of E-books for Mobile Value-added Services

This paper focuses on examining the impact that mobile value-added services may have on the process of digital learning. We explore many types of e-book readers that have been developed for the iPad, and summarize the application of gestures to communicate with a touch screen. The study analyzes popular user interfaces designs based on the characteristics of good interaction design proposed by Saffer in 2006, to assess the user interface of interactive e-books. It discusses the interface of e-books that users read and places emphasis on key points for operation gestures, content plans and interaction design. User testing was adopted to study the interaction design in reading e-books based on mobile devices. The study concludes that the participants' opinions of e-books were fairly neutral in user testing, discusses value-added services of e-books and provides a case study for the creative cooperation model. The paper offers the features of value-added services for the development and improvement of interactive e-books in the future.
