Abstract
The background of the paper is that there are currently no specifications or guidelines for the design of a user interface for an augmented reality system in an industrial context. In this area, special requirements apply for the perception and recognition of content, which are given by the framework conditions of the industrial environment, the human–technology interaction, and the work task. This paper addresses the software-technical design of augmented reality surfaces in the industrial environment. The aim is to give first design examples for software tasks by means of sample solutions. For a user-oriented implementation, the methods of personas and an empirical investigation were used. Personas are a stereotypical representation of end users that reflect their characteristics and requirements. For the subsequent development of the pattern catalog, different prototypes with layout and interaction variants were tested in an empirical study with 50 participants. By observing the current realizations, these can be examined more closely in terms of their specific use in an industrial environment. The result is a pattern catalog with 26 solutions for layout and interaction variants. For the layout variants, no direct favorite of the testers could be ascertained; the existing solutions already offer a wide spectrum, which are chosen according to personal preferences. For interaction, on the other hand, it is important to enable fast input. During the study, gesture control revealed weaknesses in this regard. This can be supportive in the development of an industrial augmented reality system regarding a user-oriented representation of the interface.
Highlights
50 probands from the industrial environment were selected according to the personas
The background of the paper is the processing of data from Industry 4.0 in quality assurance with augmented reality (AR) glasses
The research objective is to explore how the user interface of an AR system can be designed in an industrial environment
Summary
Each personaofisPattern representative of a typical user in the life phases of product planning, development/design, use. In 1977, Alexandermanufacturing/assembly, et al [42] introduced theand term pattern their publication “Ato the following phases the research. They and wereagain, obtained from the interviews conPattern Language”. Occur again pattern solutions, so-called ducted with the representative persons. The of the of tasks was given patterns, can support the solution. Patterns notdescription only describe therange problem, but they by the respective position. Of the life phases were chosen for describe the core ofprofessional the solutions.
