Characteristics of usability problems from augmented reality-based user interface for assembly task

초록

Augmented Reality (AR) is one of the cutting-edge technologies that are rapidly developing, and it is used in many areas, such as manufacturing, game and automobile industries. The purpose of this study is to get characteristics of the AR interfaces by comparing the usability problems of the AR-based manual with those of the paper-based and the video-based manuals when the assembly tasks are conducted. The task was to assemble the blocks of the LEGO. The paper-based manual was developed based on the original manual of LEGO, the video-based manual was developed as video clips of showing all steps of assembling virtual LEGO blocks, and the AR-based manual was developed as the AR application implemented on the smartphone, showing the process of assembling virtual LEGO blocks on the image target. Usability problems obtained through the experiments, which 30 participants took part in, were analyzed and the characteristics of the AR interfaces were derived from the usability problems. © 2020 ISSN 1881-803X.
