Abstract

Recently, image code interfaces and designed image codes, which can present visual information such as shapes, colors, text, images, and textures within the image code, have attracted increasing interest for use in mobile computing environments. In this paper, we introduce designed image codes and their basic decoding techniques; furthermore, we compare and analyze user preferences by performing a user study. We also implement a high-fidelity prototype of an image code interface based on a mobile computing environment and evaluate its usability by performing a user evaluation. From the evaluation, it is observed that the participants prefer a color-based image code, and this image code has a better merit rating.
