Description

E-books have an advantage over printed books in that they allow users to read multiple books on a device such as a tablet or a smartphone. However, e-books also have drawbacks, such as the lack of book weight and of paper-like texture.This study proposes a method in which a user can read while experiencing the tactile sensations of book weight and paper feel through the superimposed display of an e-book page on paper space using augmented reality. Book pages deform to various shapes depending on the way a book is held. If an e-book is superimposed and displayed without adapting to changes in the paper space, differences in visual and tactile information are created and cause discomfort to the user. Therefore, in this study, a proposed method was applied that estimates the curvature of a book and applies a correction to the projection, and the accuracy of the corrections was measured. We implemented the proposed system using HMD or smartphone. The effectiveness of the method was verified with respect to the usability of the proposed system through an experiment with test subjects.
