A Usability Evaluation of Public Icon Interface

Existing image codes interface needs additional visual marker and explanation of the service, To overcome these limitations, there were some researches to use a public icon as an anchor. The public icon is human-readable and does not need additional visual marker or explanation. In this paper, we carried out the usability evaluation of the public icon interface with a high-fidelity prototype in comparison to the existing image code. In addition, we analyze user preferences from the results. From the analysis, we perceived that the public icon interface is better to use in the public because the public icon interface is familiar with people and doesn't need additional materials or much cognitive load and are in good harmony with current environments.
