| Abstract: |
| With the rapid development of AR digital information in the field of assisted assembly, this paper aims to improve assembly efficiency, accuracy and reduce operation errors for users. However, the visual design of augmented reality assembly indicators has not standardized theoretical guidance. How to solve the user experience problem of indicators in the augmented reality assisted assembly interactive interface has become the research focus. Taking augmented reality aided mechanical assembly as an example, the dimension and state of augmented reality assembly indicators were quantitatively analyzed and evaluated based on eye tracking, and then the design strategy of augmented reality assembly indicators was proposed. The final results demonstrated that:(1) Dimension and state of augmented reality assembly indicators have significant impact on the cognitive load of indicators, and the cognitive load of dynamic and 3D indicators is larger. (2) State of augmented reality assembly indicators have significant impact on the visual prominence of indicators, and the visual prominence of dynamic indicators is stronger. (3) State of augmented reality assembly indicators have significant impact on the assembly efficiency of assembly tasks, and the assembly efficiency of dynamic indicators is higher. (4) State of augmented reality assembly indicators have significant impact on the assembly quality of assembly tasks, and the assembly quality is higher under the guidance of static indicators. The study results can be cumulative in future research, and have the theoretical value and practical meaning for augmented reality assembly indicators interaction design. |
