Computerized Assessment of the Skills of Impaired and Elderly Workers. A Tool Survey and Comparative Study

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

Gamification of a Workday. A Study on the Effects in Sheltered Employment

CHI-16-LBW-gamification-workdayIn: CHI ’16 Extended Abstracts of the ACM SIGCHI Conference on Human Factors in Computing Systems, ACM, New York, NY, USA, 2016
DOI = 10.1145/2851581.2892283

Abstract

Gamification implies the application of methods and design patterns from gaming to non-gaming areas like learning or working. We applied an existing gamification design to production processes in an organization which provides sheltered employment for impaired persons.

In contrast to existing work, we investigated not only a short period but a complete workday to measure the effects on the performance of impaired workers.

The study indicates that gamification has
(1) a negative effect on workers with considerable cognitive impairments,
(2) no measurable effect on workers with medium cognitive impairments and
(3) a positive effect on workers with mild cognitive impairments.

Design Approaches for the Gamification of Production Environments. A Study Focusing on Acceptance

DOI = 10.1145/2769493.2769549

Abstract

Gamification is an ever more popular method to increase motivation and user experience in real-world settings. It is widely used in the areas of marketing, health and education. However, in production environments, it is a new concept. To be accepted in the industrial domain, it has to be seamlessly integrated in the regular work processes.

In this work we make the following contributions to the field of gamification in production: (1) we analyze the state of the art and introduce domain-specific requirements; (2) we present two implementations gamifying production based on alternative design approaches; (3) these are evaluated in a sheltered work organization. The comparative study focuses acceptance, motivation and perceived happiness.

The results reveal that a pyramid design showing each work process as a step on the way towards a cup at the top is strongly preferred to a more abstract approach where the processes are represented by a single circle and two bars.

Towards a Gamification of Industrial Production. A Comparative Study in Sheltered Work Environments

In: Proceedings of the 7th ACM SIGCHI Symposium on Engineering Interactive Computing Systems, ACM, New York, NY, USA, 2015 [to be published]
DOI = 10.1145/2774225.2774834

Abstract

Using video game elements to improve user experience and user engagement in non-game applications is called “gamification”. This method of enriching human-computer interaction has been applied successfully in education, health and general business processes. However, it has not been established in industrial production so far.

After discussing the requirements specific for the production domain we present two workplaces augmented with gamification. Both implementations are based on a common framework for context-aware assistive systems but exemplify different approaches: the visualization of work performance is complex in System 1 and simple in System 2.

Based on two studies in sheltered work environments with impaired workers, we analyze and compare the systems’ effects on work and on workers. We show that gamification leads to a speed-accuracy-tradeoff if no quality-related feedback is provided. Another finding is that there is a highly significant raise in acceptance if a straightforward visualization approach for gamification is used.

Context-aware Assistive Systems at the Workplace. Analyzing the Effects of Projection and Gamification

In: PETRA ’14 Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments, ACM, New York, NY, USA, 2014
DOI =10.1145/2674396.2674406

Abstract

Context-aware assistive systems (CAAS) have become ubiquitous in cars or smartphones but not in industrial work contexts: while there are systems controlling work results, context-specific assistance during the processes is hardly offered. As a result production workers still have to rely on their skills and expertise. While un-impaired workers may cope well with this situation, elderly or impaired persons in production environments need context-sensitive assistance.

The contribution of the research presented here is three-fold: (1) We provide a framework for context-aware assistive systems in production environments. These systems are based on motion recognition and use projection and elements from game design (gamification) to augment work. (2) Based on this framework we describe a prototype with respect to both the physical and the software implementation. (3) We present the results of a study with impaired workers and quantifying the effects of the augmentations on work speed and quality.

On October 23rd 2013 the Special-Research Award for Human-Technology-Interaction by the Gips-Schüle-Foundation was awarded to the project ASLM. With the research lab located at the University of Applied Sciences Esslingen, the project aimed to develop a new kind of assistive system to support persons with impairments in production environments. The new assistive system uses motion tracking and projection. Within the project gamification elements were explored to improve motivation and work satisfaction. The system was constructed and built with the support of the company Schnaithmann. The system was evaluated at the sheltered work organization BWH Heilbronn. We congratulate the three awardees.

Basic research on assistive systems using motion recognition, projection and gamification can be found in the following publications:

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.
