Augmented Reality Coloring Book with Transitional User Interface

Background/Objectives: There has been a growing interest in augmented reality with the recent advancements in computer technologies. Head mounted displays which were once very expensive hardware devices are now available at low cost, which has led to the increase in the applications of AR technology. Methods/Statistical Analysis: In this paper, we describe an AR coloring book with a transitional user interface. It comprises a paper book and a smart phone application. The proposed AR coloring book enables the user to enjoy content by switching between real world, augmented reality, virtual reality, and networked virtual reality. Findings: All worlds are seamlessly connected to each other, thereby enabling the users to the same content with different modality and visualization ways. To evaluate our proposed idea, we developed the PlayingHouse, which is a transitional user interface AR coloring book. Improvements: We believe our work will lead to the popularization of AR coloring books in the future.
