“…Augmented Reality has been applied to assembly tasks and tested in user studies such as Tang et al [27], Henderson et al [11] and Boud et al [5], which evaluate and demonstrate the advantages of using AR techniques over the traditional figure-based techniques. Hou et al [12] have argued the benefits of using augmented reality and also mention the idea of playing prerecorded animation clips at each step of the assembly which are better than static figures. In all these systems, highly specialized equipment is needed, the models are typically stationary and the motion cues are due to parallax caused by head motion.…”

We demonstrate a realtime system which infers and tracks the assembly process of a snap-together block model using a Kinect R sensor. The inference enables us to build a virtual replica of the model at every step. Tracking enables us to provide context specific visual feedback on a screen by augmenting the rendered virtual model aligned with the physical model. The system allows users to author a new model and uses the inferred assembly process to guide its recreation by others. We propose a novel way of assembly guidance where the next block to be added is rendered in blinking mode with the tracked virtual model on screen. The system is also able to detect any mistakes made and helps correct them by providing appropriate feedback. We focus on assemblies of Duplo R blocks.We discuss the shortcomings of existing methods of guidance -static figures or recorded videos -and demonstrate how our method avoids those shortcomings. We also report on a user study to compare our system with standard figure-based guidance methods found in user manuals. The results of the user study suggest that our method is able to aid users' structural perception of the model better, leads to fewer assembly errors, and reduces model construction time.

“…While designing an assembly manual based on drawings, it is desirable that it contents information of at least four different types: information about the visual percepts of the components; information about shape, dimensions, volume, position; quality requirements; and the steps to install and testing the assembly (Hou & Wang, 2010). Understanding (read, comprehends, select, filter, analyze, and synthetize) the information presented based on drawings requires time and high amounts of cognitive workload (Neumann & Majoros, 1998;Towne, 1985), which most of the time is not considered (Abe & Tsuji, 1987).…”

The assembly process is often very complex and involved, collecting and managing a significant number of parts in an intricate manner. Because the quality of a product is in large part impacted by the assembly process, intuitive and carefully scaffolded guidelines can make a difference in how fast and how accurate an assembler can complete the assembly process. To this end, the authors propose an innovative system that leverages three current and emerging technologies; augmented reality (AR), cloud computing, and mobile devices, to create an Augmented Reality Product Assembly (ARPA) system. This paper describes the total framework for creating the ARPA system. They also discuss how the system leverages augmented reality visualizations for repurposing user-generated assembly guidelines by incorporating cloud-based computing. Although the authors situate ARPA’s use in an industrial setting, it is domain-independent and able to support a wide range of practical and educational applications.

“…They demonstrated that AR is very much liked by end-users and there is a strong demand for this by industry. Hou [121,122] provided a summary of all the performance issues related to AR guided assembly viewers. The researchers found that users were initially disoriented with AR viewers due to the floating nature of objects and immersion was not fully achieved.…”
