| Background This study investigated the effect on the user's subjective assessments according to the degree of overlapping between figure and ground. The concerning two elements of AR HUD navigation design are concept and transparency. Therefore, this study explored how concept and transparency of AR HUD navigation design affect the subjective usability, and which concept and transparency are appropriate under various background conditions.
Methods Concept and Transparency were measured for each condition in the combination of day/night and complex/simple. Participants were randomly assigned to each condition and watched the video of HUD navigation. Perceived visibility, intrusiveness, distractiveness, convenience, preference, satisfaction were measured as dependent variables. Repeated ANOVA was conducted to analyze the dependent variables.
Result The results showed that regardless of conditions, concept and transparency affect dependent variables. Specifically, boomerang can lead more positive user evaluation with lower transparency. Moreover, it revealed that there are appropriate concept and transparency for each background conditions.
Conclusion The significance of this study is that it revealed the importance of transparency and concept in the navigation design of AR HUD. Moreover this study expanded the research area of AR HUD navigation design. |
