Authoring Tool for Automatic Generation of Augmented Reality Instruction Sequence for Manual Operations

Book Contribution - Book Chapter Conference Contribution

Despite the large-scale digitalization and automation of production lines, humanoperators still play a vital role in the shopfloor. Operators provide flexibility and agileresponsiveness with their actions, as well as capability to react autonomously basedon their technical knowledge and experience. Bridging the gap between modern digitalsystems of information creation and management and humans in the shopfloor is acurrent challenge for both the academia and the technology integrators. One emergingway for delivering instructions to the operators is Augmented Reality (AR). AR allowsthe visualization of the instructions in the operator's field of view, using digital designs,animations and text instructions. As this technology gains increasingly more ground inthe shopfloor, there is a need for agile generation of content, automatizing most of theinstructions' generation process. Towards that end, this paper presents an authoringtool for generating digital instructions for manual operations. The authoring tool allowsthe identification of the (dis-)assembly sequence of a product and also to includeintermediate manual operations, such as surface treatment, and visualizations. In orderto determine which assembly tasks and instructions are the most commonly needed,contextual inquiries were conducted in collaboration with the industry. These findings,together with the existing literature on manual processes on the shopfloor, served as astarting point for a taxonomy of assembly task types that are also presented in thispaper. The taxonomy serves as a guide to define the processes on which digitalinstructions and visualizations can be provided. The result can be delivered as digitalon-screen instructions or as an Augmented Reality application that may target mobiledevices and headsets. The proposed approach is validated in an industrial use case ofa compressor assembly.
