Cognitive-oriented Process Information Presentation for Augmented Reality Assisted Product Assembly

Abstract

The information assistance during manual assembly process of mass customization production is indispensable in order to assure the assembly quality. The complexity of searching information and difficulty of understanding information brings about cognition burdens of workers under the varied and lengthy assembly process, where augmented reality (AR) can be an effective instruction tool. The cognitive issues of AR based information presentation for assembly guidance were discussed in this paper. The work about complexity of manual assembly process was analyzed both on error prediction and AR based cognitive perspective of visual assets. A four levels hierarchical task analysis was conducted for assembly process with three kinds of assembly stages, i.e. selection, installation and inspection. Cognitive reliability and error analysis method was taken to identify the possible human assembly errors during three stages considering the human cognitive activity and function. In order to provide right information at right place and right time for decreasing the assembly errors, the often used visual assets, i.e. 3D model, 2D annotation, text and video, were discussed for conveying assembly instruction intention in AR scenario. From the authoring complexity and potential cognitive efficiency aspects, different information presentation styles for three assembly stages were described.
