Augmented reality (AR) is an efficient form of delivering spatial information and has great potential for training workers. However, AR is still not widely used for such scenarios due to the technical skills and expertise required to create interactive AR content. We developed ProcessAR, an AR-based system to develop 2D/3D content that captures subject matter expert’s (SMEs) environment object interactions in situ. The design space for ProcessAR was identified from formative interviews with AR programming experts and SMEs, alongside a comparative design study with SMEs and novice users. To enable smooth workflows, ProcessAR locates and identifies different tools/objects through computer vision within the workspace when the author looks at them. We explored additional features such as embedding 2D videos with detected objects and user-adaptive triggers. A final user evaluation comparing ProcessAR and a baseline AR authoring environment showed that, according to our qualitative questionnaire, users preferred ProcessAR.

Subramanian Chidambaram is a Ph.D student in the School of Mechanical Engineering at Purdue University. Prior to joining the C Design lab, he obtained his Master’s from the School of Aeronautics and Astronautics also from Purdue and a Bachelor’s degree in Mechanical engineering from Vellore Institute of Technology, India. His current research interest involves exploring Human-Computer Interactions and Digital interface development for Augmented Reality (AR), embedding Artificial Intelligence (AI) in AR interface development, Skill transfer through AR, tangible interfaces and geometric modeling. In the past, he has also conducted research on developing tools that guide novices to design analyze and fabricate functional load-bearing structures.
