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.     

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.

Introducing ergonomics requirements in the eco-design of energy-related products from users’ behaviour approach

Ergonomics has been a very important activity in the design process. However, ergonomics rarely includes the environmental requirements into the design of products. The article proposes and presents the Eco-Ergo model through its application to a real-world product, a washing machine, to allow designers and ergonomists to establish product design requirements in order to minimise environmental impacts related to user–product interaction during the use stage. This model uses a visual language of representation, Blueprinting-based, that helps designers explore problems they have not previously considered during the market research when a wide variety of products with different interaction elements is analysed. The application of this model allows direct efforts and attention on the user analysis phase in the most influential user’s actions on the environmental performance of energy-related products during use, establishing ergonomics requirements related to users behaviour at the initial design phase.

Practitioner summary: This study provides a proposal to incorporate ergonomics into the practice of eco-design through the use of human factors in the establishment of initial eco-design requirements. This blueprint-based model combines an empirical and theoretical approach, based on the product test developed by designers, ergonomists and environmentalists.

Nanomaterials in the field of design ergonomics: present status

Application of nanotechnology and nanomaterials is not new in the field of design, but a recent trend of extensive use of nanomaterials in product and/or workplace design is drawing attention of design researchers all over the world. In the present paper, an attempt has been made to describe the diverse use of nanomaterials in product and workplace design with special emphasis on ergonomics (occupational health and safety; thermo-regulation and work efficiency, cognitive interface design; maintenance of workplace, etc.) to popularise the new discipline ‘nanoergonomics’ among designers, design users and design researchers. Nanoergonomics for sustainable product and workplace design by minimising occupational health risks has been felt by the authors to be an emerging research area in coming years.

Practitioner Summary: Use of nanomaterials in the field of design ergonomics is less explored till date. In the present review, an attempt has been made to extend general awareness among ergonomists/designers about applications of nanomaterials/nanotechnology in the field of design ergonomics and about health implications of nanomaterials during their use.     

A method for integrating ergonomics analysis into maintainability design in a virtual environment

Designers must consider human factors/ergonomics when making decisions from the perspective of maintainability. As an important aspect of maintainability, maintenance space should be made adequate at the design stage to achieve a convenient maintenance process. A maintenance space evaluation method that considers ergonomics is proposed in this study. By comparing free swept volumes and constrained swept volumes in a virtual environment, maintenance space could be evaluated quantitatively and objectively. The results of the evaluation are obtained by combining the principles of ergonomics and maintainability. These results can help designers improve product design such that it fits ergonomics and maintainability requirements. A case study is introduced at the end of this paper to demonstrate the feasibility of the proposed method in efficiently evaluating the maintenance space based on the layout design of the product components in the design stage.Relevant to industryFor a large number of disasters caused by human errors in current industry, the result of this study contributes a guide to fully consider human factors in maintainability design through virtual environment and is beneficial to designers and engineers of industrial application fields.

Abstract

The benefits for the consumer, and for the practising ergonomist of implementing a marketing strategy designed to increase consumer awareness of ergonomics is discussed with reference to the experiences of ICE Ergonomics, a commercial ergonomics research and consultancy organization based in Great Britain. The marketing strategy, which addresses the areas of publicity, education and practical involvement, forms one part of an integrated marketing strategy now being implemented by ICE.     

Designing time at the user interface

This paper describes research that seeks to facilitate the capture, representation, and reasoning about, temporal information by usability engineers. The product, a method we call KAT-LITTER, is an extension of Johnson and Johnson's (1991) Knowledge Analysis of Tasks (KAT). An evaluation of KAT-LITTER showed that it influenced the design process in two significant ways: firstly, designers using KAT-LITTER spent more time reasoning about temporal issues than designers using KAT alone, and secondly these same designers considered a broader spectrum of temporal issues. Further developments of KAT-LITTER are briefly discussed.     

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 Northern Ireland: a survey of knowledge,attitudes, and implementation in industry and the public services

Abstract

In spite of the palpable benefits to organizations of applying the principles of ergonomics, it appears that a majority of employers, whether through ignorance or neglect, fail to do so (Simpson 1990). The present study sought to assess the impact of ergonomics on a broad cross-section of organizations in Northern Ireland from three perspectives: (1) knowledge and awareness of ergonomics; (2) attitudes towards ergonomics; and (3) the extent to which the principles of ergonomics were put into practice in the work-place. In all, 700 organizations were surveyed, representing manufacturing, service, and public sectors and ranging in size from 10 to more than 1000 employees. A total of 417 questionnaires (59·7%) were returned and, of these, 152 (36·5%) claimed no knowledge whatever of ergonomics. The extent to which knowledge was claimed tended to depend on the nature of the organizations. Analysis of the remaining 263 questionnaires revealed that, while only 36 organizations employed ergonomic specialists or engaged outside ergonomic consultants, 163 respondents reported specific instances of addressing ergonomic issues during the previous 12 months. Respondents exhibited generally positive attitudes towards ergonomics, although some cynicism was evident. Principal components analysis of the questionnaire items revealed several factors, most notably a general concern for ergonomic issues, cynicism towards ergonomics and, arguably, an attitude of helplessness concerning the state of the organization. Implications of these findings for promoting implementation of ergonomics within organizations are discussed.     

A survey of anthropometry and physical accommodation in ergonomics curricula

The size and shape of users are an important consideration for many products and environments. Designers and engineers in many disciplines must often accommodate these attributes to meet objectives such as fit and safety. When practitioners have academic training in addressing these issues, it is typically through courses in Human Factors/Ergonomics (HF/E). This paper investigates education related to physical accommodation and offers suggestions for improvement. A survey was conducted wherein 21 instructors at 18 universities in the United States provided syllabi for 29 courses, which were analysed to determine topics related to anthropometry and resources used for the courses. The results show that within the US, anthropometry is covered in the majority of courses discussing physical ergonomics, but important related concepts were often omitted (e.g. digital human modelling, multivariate accommodation and variability across global populations). Curricula could be improved by incorporating more accurate anthropometry, multivariate problems and interactive online tools.

Practitioner Summary: This paper describes a study investigating collegiate ergonomics courses within the US in the area of physical accommodation. Course schedules and texts were studied for their treatment of several topics related to accommodating the spatial requirements (anthropometry) of users. Recommendations are made for improving course curricula.     

Contribution of ergonomics to the design of antireflection devices in the development of VDU workplaces

Abstract

The design of the early Olivetti VDU workplaces used the micromesh filter as an antireflection device. New ergonomic problems related to the use of the VDUs have forced the designers to adopt the etching treatment on new VDUs and to supply them with the micromesh filter only in cases of particularly highly lit environments. Afterwards, in order to give the operator the opportunity of using the preferred colour of the character, the designers set up coloured plastic filters, which also show good antireflection effectiveness. In this case, the choice of correct colours and the determination of the best compromise between antireflection effectiveness and character sharpness are the contribution of ergonomics to the design of the filters. In this paper the different antireflection devices and their ergonomic evaluation are presented and discussed.     

On Educational Ergonomics

Abstract

This paper represents an effort to establish an inter-disciplinary field of research toward total educational effectiveness. The traditional educational delivery lacks any systems perspective and precision. The application of ergonomics to education has received only limited attention. A systems analysis has identified 5 components for educational ergonomics: (1) learning ergonomics, (2) instructional ergonomics, (3) orgonomics of educational facilities, (4) ergonomics of educational oqutpment, and (5) the ergonomics of educational environment.

Learning ergonomics explores such areas as educational skills of handwriting, roading, drawing, instrument manipulation, class scheduling and school scheduling, research in examinations, management of learning activities, and grading systems. The instructional ergonomics covers textbook design, teaching devices, instruction techniques, classroom conducts, lecture preparation, and educational T.V. Ergonomics of educational facilities concerns educational furniture, laboratory and library ergonomics, classroom and office design, and equipment allocation. Ergonomics of education equipment investigates needs analysis, C/D design, allocation of equipment, performance analyses, and its safety and construction. Ergonomics of educational environment includes such things as illumination, colour, noise, space utilization, and allocation of equipment. Within each variable, research is reviewed and typical studies are suggested. The value of an integrated discipline of educational ergonomics is also discussed.     

TECHNICAL NOTE: Design criteria for microclimate cooling systems

Abstract

This paper identifies and described 25 design criteria that are desirable characteristics for a microclimate cooling system (MCCS). These criteria can be used as a check list by designers when developing an MCCS, and by organizations when evaluating and selecting MCCSs for use by their employees.

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.     

Human-computer interface design and implementation details

Abstract

The paper presents a model of how the availability of implementation details affects performance in designing a human-computer interface. Two experiments have been used to test the validity of this model. The experiments involved varying the amount of implementation detail presented to interface designers and having the designers perform an interface design task. The amount of work performed and the quality of the resulting human-computer interface design are analysed.

The results presented in this paper show that the quality of a human-computer interface design improves if the designer is presented with some information about implementation details. However, presenting a designer with all implementation details of the system functions results in a lower quality design. The relevance of these results to human-computer interface design and future directions for research are discussed.     

Green ergonomics: challenges and opportunities

Addressing the causes and consequences of environmental degradation presents significant challenges for humankind. This paper considers what ergonomics/human factors (E/HF) professionals can contribute to understanding and tackling some of the issues that arise through the movement towards a more environmentally sustainable economy. These issues are considered in relation to work in green industries (specifically, sustainable energy production, recycling and organic food production), and there is a need to ensure that these jobs are safe and healthy; the design of products and systems that are ‘environmentally friendly’ to facilitate their acceptability and use and how E/HF professionals can contribute to understanding and promoting behavioural change relating to environmental choices. The activities of some international organisations in this area are identified and the potential for E/HF involvement is considered. The implications for the E/HF profession are discussed.

Practitioner summary: This paper considers how ergonomics/human factors professionals can contribute to the movement towards more sustainable and ‘environmentally friendly’ design and work. Potential challenges and opportunities are discussed in relation to jobs in green industries, products and systems and behaviour change.     

An overview of consumer ergonomics in the United Kingdom

Consumer ergonomics has emerged as one of the mainstream areas of ergonomics research and application. This paper discusses the background to this development and provides a framework for the three special issues of Applied Ergonomics devoted to this topic. The main aspects of current consumer ergonomics research, for example the fields of application, available techniques and relevant criteria, are reviewed by drawing on papers from this special series and other complementary published work. Some criticisms are made relating to the failure to achieve the systematic application of ergonomics in the design process, and a series of recommendations is made as to how the contribution of ergonomics could be made more effective. Finally, the future of consumer ergonomics in considered in the light of three major trends - the increased complexity of products, changes in social climate and forthcoming changes in consumer legislation.
