Augmentierte Produktion. Assistenzsysteme mit Projektion und Gamification für leistungsgeminderte und leistungsgewandelte Menschen

Abstract

Assistenzsysteme in der Produktion beschränken sich bislang darauf, Werkern Instruktionen zur Montage von Produkten zu geben. Eine Anpassung an die körperlichen und geistigen Fähigkeiten des Anwenders findet bislang nicht statt. Auch neue Konzepte der Mensch-Maschine-Interaktion (MMI) finden nur langsam Anwendung. Mit dem Prototypen eines augmentierten Assistenzsystems haben wir experimentell untersucht, wie zwei neuere Ansätze der MMI sich auf die Leistungsfähigkeit von Personen mit Leistungsminderungen auswirken: Die Projektion von Informationen direkt in den Arbeitsbereich (in-situ) und die Anreicherung von Arbeitsprozessen mit spielerischen Elementen (Gamification). Zugleich wurde die Akzeptanz solcher Systeme untersucht.

Abstract

Production work requires a high level of awareness and especially manual assembly work is prone to human errors. At the same time the demand for manual assembly grows. Assistive systems in production environments (ASiPE) have to be augmented to improve the overall performance and reduce skill requirements.

In this study the prototype of an augmented ASiPE is applied in an experiment with impaired persons. It uses in-situ projection (i.e. the projection of work-relevant information directly into the working space, Figures 1, 8) to cognitively assist users in assembly and to improve their inclusion in regular work processes. The aim is to observe their behavior with this new form of human computer interaction and to empirically quantify the effects on performance both in time and quality.

The results show that the augmentation has a catalytic effect: The test subjects assembling slowly could not cope with the augmented ASiPE and performed worse than their counterparts without augmentation. The test subjects who worked faster than average assembled the product significantly better, both with respect to time (14.5% reduction) and especially to quality (45.8% error reduction). The ability to access the potential of augmented workplaces seems to be related to a worker’ cognitive potential which is not adequately mapped by the competence ratios sheltered work organizations currently use.

Abstract

Interactive projections have been around for more than a decade. We measured their potentials for augmented workplaces in production. For this purpose we built the prototype of an assistive system projecting instructions directly into the workspace (in situ). While it can be applied in every production environment, the system was first implemented and tested where it is needed the most: in a sheltered work organization employing persons with impairments.

It could be shown that the assembly times could be slightly reduced by the augmented system. However it had a “catalytic” effect on the test subjects’ work quality: While some seem to be overwhelmed by the new information density and perform worse, others perform much better than the control group and significantly reduce error rates. The qualitative results show that although impaired persons retain a critical perspective on systems directly changing the way they have been working for years, all users would like to retry working with the system. When looking at additional aids like the projection of a real-sized model in the workspace, the users invariantly accept its benefits for their assembly work.

Abstract

This paper introduces the toolkit ASED: Assistive System Experiment Designer. Combining a specially constructed assembly table and new software it allows measuring the performance of impaired persons when using assistive systems for production environments (ASiPE). The ASiPE design tested using ASED transgresses the state of the art by three enhancements. With the help of ASED we are able to quantify and rank their effects on work quality and performance. The ASED toolkit, however, is not confined to the design tested but can be used for the experimental analysis of every kind of manual process.
