MS Dissertation title: Evaluation of graphical user interfaces for augmented reality based manual assembly support

MS Advisor(s): James Oliver

Area of MS research: Augmented reality (AR) technology is advancing rapidly and promises benefits to a wide variety of applications-including manual assembly and maintenance tasks. This thesis addresses the design of user interfaces for AR applications, focusing specifically on information presentation interface elements for assembly tasks. A framework was developed and utilized to understand and classify these elements, as well as to evaluate numerous existing AR assembly interfaces from literature. Furthermore, a user study was conducted to investigate the strengths and weaknesses of concrete and abstract AR interface elements in an assembly scenario, as well as to compare AR assembly instructions against common paper-based assembly instructions. The results of this study supported, at least partially, the three hypotheses that concrete AR elements are more suitable to convey part manipulation information than abstract AR elements, that concrete AR and paper-based instructions lead to faster assembly times than abstract AR instructions alone, and that concrete AR instructions lead to greater increases in user confidence than paper-based instructions. The study failed to support the hypothesis that abstract AR elements are more suitable for part identification than concrete AR elements. Finally, the study results and hypothesis conclusions are used to suggest future work regarding interface element design for AR assembly applications.
