Paranga

Abstract

The authors propose a novel book-shaped device for flipbooks called Paranga that embodies both physical features of paper and e-book interactivity. Paranga detects how quickly a user is riffling and provides the user with visual, tactile, and auditory feedbacks of turned pages by employing an LCD monitor and a rotatable roller mechanism with pieces of real paper. Using this device, the authors created several electronic flipbook installations in which the story changes depending on page-turning speed. This paper details the implementation of this device, describes the users’ reactions at a conference exhibition, and discusses Paranga's possible applications.
