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

This chapter introduces the prototype of a software developed to assist elderly persons in performing physical exercises to prevent falls. The result — a combination of sport exercises and gaming — is also called “exergame.” The software is based on research and development conducted within the
“motivotion60+” research project as part of the AAL-program (Ambient Assisted Living).

The authors outline the use of motion recognition and analysis to promote physical activity among elderly people: it allows Natural Interaction (NI) and takes away the conventional controller, which represented a hurdle for the acceptance of technical solutions in the target group; it allows the real-time scaling of the exergame’s difficulty to adjust to the user’s individual fitness level and thus keep motivation up. The authors’ experiences with the design of the exergame and the first results from its evaluation regarding space, interaction, design, effort, and fun, as well as human factors, are portrayed. The authors also give an outlook on what future exergames using motion recognition should look like.
