The development of computer‐based tools to support ergonomics in design education and practice

Abstract

Ergonomics is not always used effectively by practising designers, and is still seen as limiting their creativity. Reasons for this include: ergonomics information is not presented in a readily assimilated form to designers during their design education and later design activities; design decisions relating to ergonomics issues are not addressed and discussed systematically by all members of the design team during concept design; the user centred approach that ergonomics encourages in design is not always included as part of the education of future designers.

With computers being used more widely in design and design education, they could be used to deliver ergonomics information and help structure discussion of ergonomics issues amongst the design team from the earliest stages of design. This paper describes findings relating to the use of ergonomics in automotive design, and proposes two tools which could enhance the use of ergonomics in design education and in current and future design practice.

Fitting methods to paradigms: are ergonomics methods fit for systems thinking?

Abstract

The issues being tackled within ergonomics problem spaces are shifting. Although existing paradigms appear relevant for modern day systems, it is worth questioning whether our methods are. This paper asks whether the complexities of systems thinking, a currently ubiquitous ergonomics paradigm, are outpacing the capabilities of our methodological toolkit. This is achieved through examining the contemporary ergonomics problem space and the extent to which ergonomics methods can meet the challenges posed. Specifically, five key areas within the ergonomics paradigm of systems thinking are focused on: normal performance as a cause of accidents, accident prediction, system migration, systems concepts and ergonomics in design. The methods available for pursuing each line of inquiry are discussed, along with their ability to respond to key requirements. In doing so, a series of new methodological requirements and capabilities are identified. It is argued that further methodological development is required to provide researchers and practitioners with appropriate tools to explore both contemporary and future problems.

Practitioner Summary: Ergonomics methods are the cornerstone of our discipline. This paper examines whether our current methodological toolkit is fit for purpose given the changing nature of ergonomics problems. The findings provide key research and practice requirements for methodological development.

Do we need sustainability as a new approach in human factors and ergonomics?

The International Ergonomics Association Technical Committee ‘Human Factors and Sustainable Development’ was established to contribute to a broad discourse about opportunities and risks resulting from current societal ‘mega-trends’ and their impacts on the interactions among humans and other elements of a system, e.g. in work systems. This paper focuses on the underlying key issues: how do the sustainability paradigm and human factors/ergonomics interplay and interact, and is sustainability necessary as a new approach for our discipline? Based on a discussion of the sustainability concept, some general principles for designing new and enhancing existent approaches of human factors and ergonomics regarding their orientation towards sustainability are proposed.

Practitioner summary: The increasing profile of sustainability on the international stage presents new opportunities for human factors/ergonomics. Positioning of the sustainability paradigm within human factors/ergonomics is discussed. Approaches to incorporating sustainability in the design of work systems are considered.

The IEA contribution to the transition of Ergonomics from research to practice

The future growth of ergonomics as a scientific discipline will require a greater focus on methods to transition research findings into practice. Whilst the International Ergonomics Association (IEA) and the Federated Ergonomics Societies provide opportunities to promote exchange on ergonomics research and collaboration in research programs, the future sustainability of the domain will be dependent on the provision of ongoing educational opportunities in ergonomics and the transitioning of the research findings into practice. This transition will require greater external focus outside the ergonomics profession in working in collaboration and partnership with other professional associations, governments and international agencies. Practical tools that are targeted towards particular user groups within the community, workplace, and governments will enhance the opportunities for the transition of ergonomics research into practice. Focus on extramural initiatives such as Ergonomics Checkpoints, integration of the ergonomics design process into the International Organisation for Standardization Guidelines, and the incorporation of ergonomics into the World Health Organisation research programs will ensure that the positioning of ergonomics will continue at an international level.     

Ergonomics and sustainability: towards an embrace of complexity and emergence

Technology offers a promising route to a sustainable future, and ergonomics can serve a vital role. The argument of this article is that the lasting success of sustainability initiatives in ergonomics hinges on an examination of ergonomics’ own epistemology and ethics. The epistemology of ergonomics is fundamentally empiricist and positivist. This places practical constraints on its ability to address important issues such as sustainability, emergence and complexity. The implicit ethical position of ergonomics is one of neutrality, and its positivist epistemology generally puts value-laden questions outside the parameters of what it sees as scientific practice. We argue, by contrast, that a discipline that deals with both technology and human beings cannot avoid engaging with questions of complexity and emergence and seeking innovative ways of addressing these issues.

Practitioner Summary: Ergonomics has largely modelled its research on a reductive science, studying parts and problems to fix. In sustainability efforts, this can lead to mere local adaptations with a negative effect on global sustainability. Ergonomics must consider quality of life globally, appreciating complexity and emergent effects of local relationships.     

Designing for sustainability: ergonomics – carpe diem.

Sustainability is a global issue that has worldwide attention but the role of ergonomics in designing for sustainability is poorly understood and seldom considered. An analysis of the literature on ergonomics, design and sustainability was conducted via a search of electronic databases: Scopus, Business Source Complete, Google Scholar, Emerald Publishing, Academic Search Premiere, Web of Science, Discover and Ergonomics Abstracts, for the years 1995–2012. A total of 1934 articles fulfilled the search criteria, but content analysis of the abstracts indicated that only 14 refereed articles addressed the main search criteria. Of those seven were in ergonomics journals and seven were in other journals (and were not written by ergonomists). It is concluded that the contribution of ergonomics to sustainability and sustainable design has been limited, even though the goals of sustainability and ergonomics are congruent. Ergonomists have not been at the forefront of research contributing to sustainability – and it is time for them to ‘seize the day’ – ‘carpe diem’.

Practitioner Summary: This literature review shows that ergonomics contribution to sustainability is limited but since there is congruence between the disciplines it calls for ergonomists to become more involved and to seize the day – carpe diem.     

The integration of ergonomics into design—A review

Abstract

This paper examines the role of ergonomics in product and systems design. Market requirements as well as legislation have increased the use of ergonomics in design. This has increased the demands upon both ergonomists and designers. The ergonomist must learn to participate in the product development team. In return the design team must find the time and resources necessary for the inclusion of ergonomics in the development programme. This paper discusses the different roles played by the ergonomist in each stage of product and systems design. The need to give designers, engineers and management a fundamental education in ergonomics is highlighted as is the need for the ergonomist to consider the financial consequences of his work.     

Enhancing students’ knowledge building through utilising social interactions in an online learning environment

ABSTRACT

In the new “open world” of information, educational systems should involve students in constructing new knowledge of value to a community out of fragmentary information. The already proposed Knowledge Building (KB) approaches typically support only a few general-purpose activities due to the constraints of the utilised web-based environments. To organise and facilitate students’ KB during course activities, this study incorporated services provided by DoosMooc social learning environment into a knowledge transformation model. This approach is completely adapted to an educational context and allows time for iterations, helping students to both contribute to social KB processes and take collective responsibility for improving their understanding of authentic problems. The features provided by the introduced environment support and assess students’ KB activities and facilitate processes of creating, representing, organising, and reviewing different types of knowledge artefacts. The results of a semester-long experiment indicate that the approach and the corresponding instructional design thereof could successfully organise students’ KB activities and facilitate the required interactions. This study reports the impacts of parameters such as learner expertise and quality of shared knowledge on the planned KB processes, and investigates the relationships between students' KB activities and learning achievements.     

Green ergonomics: definition and scope

This paper demonstrates that the goals of ergonomics (i.e. effectiveness, efficiency, health, safety and usability) are closely aligned with the goals of design for environmental sustainability. In this paper, the term ‘green ergonomics’ is conceptualised to specifically describe ergonomics interventions with a pro-nature emphasis. Green ergonomics is focused on the bi-directional connections between human systems and nature. This involves looking at (1) how ergonomics design and evaluation might be used to conserve, preserve, and restore nature and (2) how ecosystem services might be harnessed to facilitate the improved wellbeing and effectiveness of human systems. The paper proposes the scope of green ergonomics based on these bi-directional relationships in the areas of the design of low resource systems and products, the design of green jobs, and the design for behaviour change. Suggestions for further work in the green ergonomics domain are also made.

Practitioner Summary: Given the enormous environmental challenges facing modern industrial society, this paper encourages ergonomics science to embrace a pro-nature understanding of work design and research. This paper sets out the role for green ergonomics based on an appreciation of the human–nature connections that have been integrated with our understanding of ergonomics science and practice.     

Ergonomics in India: a case study on workspace design for an Alphacomp phototypesetting machine

Abstract

Ergonomics in India is a newly emerging discipline-having made inroads to the people of India very recently. Most of the Indians are absolutely unaware of using ergonomics to achieve an efficient man-machine-environment system for better productivity with less human cost. The present case study on workspace design for a phototypesetting machine in India indicates that people from the printing sector are ready to spend money importing modern machinery to achieve twofold objectives; (i) improvement of printing quality and (ii) faster publication. However, lack of ergonomic awareness hinders the design of a proper work environment, without which they cannot reach their goals.

The present study is aimed at designing a proper workspace for an Alphacomp model K-II phototypesetting machine, which is going to be imported by several organizations in Bombay in the near future. The equipment consists of a printer, a floppy-disc drive, a keyboard and a power-supply unit. Only a single set-up out of three existing set-ups in Bombay was studied. As well as the existing workspace arrangement, three other concepts of arranging the equipment were generated and evaluated through mock-up studies. Evaluations were based on time-movement analysis, postural problems and anthropometric requirements by using video technique, questionnaires and personal observations. Strains imposed on thighs, lumbar and shoulder regions in existing conditions were eliminated by redesigning the workspace. The time required to complete the same task in different reorganized workspace arrangements was about 14-20 min less than that of the existing condition. Considering the existing machine design as constrained and based on concept 1, a prototype for a working table has been fabricated from the viewpoint of industrial design which will be patented in near the future.     

Harmonizing professional standards in ergonomics while recognizing diversity

Abstract

High quality performance is an aspiration of all professions and processes of quality assurance are normally carefully defined. These include the design of educational programmes to ensure that graduates achieve a high standard of performance and are able to compete in the world market and meet consumers' needs; a method of evaluating the relevance and standard of that education; and a means of ensuring continuing competence in practice. The diversity of paths taken to become an ergonomist offers a challenge to ergonomics societies to define effective and equitable approaches to quality assurance. This paper advocates the definition of core ergonomics competencies as a linking resource for educational planning, accreditation processes and certification procedures. Such an approach could provide the basis for harmonization in the recognition of ergonomists with varying educational backgrounds, expertise and experience.     

The role of anthropometry in designing for sustainability

An understanding of human factors and ergonomics facilitates the design of artefacts, tasks and environments that fulfil their users’ physical and cognitive requirements. Research in these fields furthers the goal of efficiently accommodating the desired percentage of user populations through enhanced awareness and modelling of human variability. Design for sustainability (DfS) allows for these concepts to be leveraged in the broader context of designing to minimise negative impacts on the environment. This paper focuses on anthropometry and proposes three ways in which its consideration is relevant to DfS: reducing raw material consumption, increasing usage lifetimes and ethical human resource considerations. This is demonstrated through the application of anthropometry synthesis, virtual fitting, and sizing and adjustability allocation methods in the design of an industrial workstation seat for use in five distinct global populations. This work highlights the importance of and opportunities for using ergonomic design principles in DfS efforts.

Practitioner Summary: This research demonstrates the relevance of some anthropometry-based ergonomics concepts to the field of design for sustainability. A global design case study leverages human variability considerations in furthering three sustainable design goals: reducing raw material consumption, increasing usage lifetimes and incorporating ethical human resource considerations in design.     

The promises and problems of ergonomics application in the People's Republic of China

Ergonomics or human factors, as an applied science concerning the design of interfaces between man, machine and the working environment, has shown its great capacities and potentials for improving working conditions and efficiency during its applications in most industrially developed countries (IC). As a means of improving the economy, industrialisation has been initiated in many industrially developing countries (DC). Knowledge and technology available in ICs have been transferred to DCs in order to increase the process of industrialisation. Ergonomics as a western discipline has also been transferred to many DCs during the technology transfer process. As an example of the transfer and development of ergonomics in industrially developing countries, this paper examines the development of ergonomics and its various areas of application in the People's Republic of China. After reviewing the current ergonomics situation and its applications in China from various points of view — i e, from organisation, research, education and industrial application — promises and problems associatd with the development of this new area of science are discussed.     

Applications of an interaction,process, integration and intelligence (IPII) design approach for ergonomics solutions

This paper first reviews current ergonomics design approaches in delivering digital solutions to achieve a unified experience from interaction and business process design perspectives. Then, it analyses the opportunities that new technologies may bring in for enhancing current ergonomics design approaches from integration and intelligence design perspectives. To address the challenges in today’s ergonomics practices in delivering digital solutions, an interaction, process, integration and intelligence (IPII) design approach is proposed. A case study is presented that implemented the IPII approach. The quantitative data gathered from the case study demonstrates that the IPII approach has achieved significant advantages in reaching the goal of a unified experience and operational benefits for delivering digital solutions. The IPII approach also demonstrates improvements compared to today’s ergonomics design approaches, such as user-centred design, for digital solutions. Finally, the paper highlights the contributions of the IPII approach for future ergonomics practices in delivering digital solutions.

Practitioner Summary: In addition to the interaction design for the UI of digital solutions, as is the case in current typical ergonomics practice, the IPII adds three additional design components: process, integration and intelligence design. The case study demonstrates the advantages of the IPII, providing an enhanced approach for designing digital solutions.

The Impact of Differentiated Instructional Materials on English Language Learner (ELL) Students’ Comprehension of Science Laboratory Tasks

Abstract

Through a qualitative research design, this article investigates the impacts of differentiated laboratory instructional materials on English language learners’ (ELLs) laboratory task comprehension. The factors affecting ELLs’ science learning experiences are further explored. Data analysis reveals a greater degree of laboratory task comprehension when utilizing language-modified and visually modified laboratory instructional materials. The findings suggest the further development of linguistically appropriate science course materials. This study also indicates that teachers must consider the sociopsychological influences affecting the individual ELL in order to better facilitate science learning.     

The development of ergonomics data for health-building design guidance∗

Abstract

Changes in policy and resources result in health-care systems which are constantly evolving. The evolution is reflected in physical and functional changes in health-building designs.

Building design guidance must be capable of accommodating these changes without losing its validity or usefulness. This paper discusses the development of an ergonomics (i.e. user oriented) data bank, linked to a checklist of component parts (i.e. items of furniture and equipment), whose effective and efficient use and interrelationship determines the form and planning of an effective and efficient health building.

The developed data system is seen as an effective tool for quality control, which can be applied at the drawing-board stage in health-building design, and which has previously not been available.
