Abstract

The number of impaired persons rises – as a result of both regular degradation with age and psychological problems like burnout. Sheltered work organizations aim to reintegrate impaired persons into work environments and prepare them for the re-entry in the regular job market.

Both for elderly and for impaired persons it is crucial to quickly assess the abilities, to identify limits and potentials and thus find work processes suitable for their skill profile.

This work focuses on the analysis and comparison of software-tools that assess the abilities of persons with impairments. We describe two established generic tools (CANTAB, Cogstate), analyze a yet unknown specialized tool (Hamet) and present a new gamified tool (GATRAS).

Finally we present a study with 20 participants, comparing the tools against a ground truth baseline generated by a realworld assembly task

A Study with Impaired Persons

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.
