- Anthropometry, the study of human measurements, is central in the design of products and workplaces. This paper describes how Swedish anthropometric data is made available through a web page (www.antropometri.se) intended to be used by designers and engineers when developing new products and workplaces. With the anthropometric web resource it is possible to get mean and standard deviation values, and to calculate percentile values, for a number of anthropometric measurements. Further functionality on the web page enables simultaneous consideration of several anthropometric measurements. The web page also contains guidelines for how to use anthropometric data depending on the design task at hand.

Increasing automation and design of a user interface to improve the physical working situation for band saw blades straightening

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The manual work of straightening band saw blade includes tasks of poor physical ergonomics, since the needs to bend and twist the back and neck to be able to see the horizontal line of the blade. This paper presents a case study of how a physical manual work task successfully can be transferred to be machine operated, by developing agraphical user interface, and thereby improving the physical working conditions of the operators.

Use of kitting to ease assemblers' cognitive workload

- The higher level of product variation in the automotive industry leads to an increasing workload for the assembler that has to search, fetch and assemble all the variants. This puts high demands on the information that is given to the assembler to fulfil the assembly task. This paper describes the impact of information overload and sources, and their influence on the assembler. Through observations conducted in the Swedish automotive industry, the study has shown that the assembly personnel perceive the kit as structured information and that structured kits are able to present distinct information at a certain place to the assembler, which in turn reduces the searching, resulting in decreased cognitive workload.

Ergonomics in early product development - an interview study in five companies
- 2011
-
Ingår i: Nordic Ergonomics Society (NES) Annual Conference, Oulu, Finland, 18-21 sept., 2011. - 9789514295416 ; 2011, s. 40-45

Konferensbidrag (refereegranskat)abstract
- The objective was to explore how assembly ergonomics issues were regarded in early product development. Therefore, 64 stakeholders in five manufacturing companies were interviewed. Their answers show a fairly good awareness of the implications of poor assembly ergonomics but appropriate working procedures are missing. 58 respondents think that poor ergonomics can result in worse product quality. 47 state that profitability calculations are often necessary and 37 mean that ergonomics risks are taken due to missing calculation methods. Altogether, the results add further knowledge of what is required to achieve more complete and sustainable ergonomic solutions.

A description of work environment management in succesful companies

Konferensbidrag (refereegranskat)abstract
- A good work environment can support companies' competitiveness, but many managers mostly associate ergonomics with occupational health and safety. In the process of managing the work environment and creating a good working environment, company managers have a central role. This article investigated managers' own descriptions of the work environment management (WEM). The study group consisted of successful companies (n=142) in a county of Sweden. The managers' descriptions were categorised into nine categories. The most frequently described category was “PhysicalFactors at work”, followed by “Manuals and Standardisation”, and “EmployeeInvolvement and Interaction”.

Sustained periods of binocular load may affect trapezius muscle activity
- 2011
-
Ingår i: Wellbeing and innovations through ergonomics. - Oulu, Finland : Nordic Ergonomics Society. - 9789514295416 - 9789514295348 ; , s. 158-163

Konferensbidrag (refereegranskat)abstract
- The relationship between activity in ocular muscles and activity in neck and scapular muscles that stabilizes gaze is well known. However, it is uncertain if ocular load per se contributes to increased muscle activity in the neck and scapular area. Sixty-six participants performed a fixation task under three different conditions: binocular with minus lenses (-3.5D) and monocular with minus lens (-3.5D) and neutral lens (±0D). Ocular accommodation and trapezius muscle EMG were measured. Multiple regression analysis showed that response diopters accounted for 11.6% (p=0.009) of the variance in EMG in the binocular condition. In the monocular conditions, there were no significant relationships.

Do small- and medium-sized enterprises differ in their work environment priorities?
- 2011

Konferensbidrag (refereegranskat)abstract
- Companies differ to what extent they attend to their work environments, despite that every employer is obliged to follow the national legislations on occupational, health and safety (OHS). Earlier evidence suggests that small and larger companies significantly differ in quality in how they handle their OHS activities. This study used questionnaire data from 106 small- and medium-sized companies. The findings were contrary to what could be expected, since no significant differences between company sizes were found. It is important to consider if it is factual or perceptual differences that’s being compared when examining companies’ work environment management.

Risk exposure assessment of dynamic wrist motions of a digital human model

Konferensbidrag (refereegranskat)abstract
- Software tools as Digital Human Modelling (DHM) has been designed to simulate and visualize the human work and to assess ergonomics conditions. No methods in commercial DHM software calculate time-dependent information, which is adequate in defining the relations between exposure and risk of disorders. The paper presents and discusses how an assembly task can be analysed with the help from a DHM-tool. Out comes from the study revealed that it is possible to generate output files with time-dependent wrist exposure data from a manikin in a DHM-tool. However, current evaluation methods do not take time-dependent information into consideration.

Enabling end-user participation in ship design
- 2011

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The globalized nature of the shipping industry poses challenges to a traditional set-up of a collaborativedesign and development team involving end-users. The present study explores aspects of end-user involvement and three different 3D models’ abilities to act as boundary objects in a ship design process.The preliminary results indicate that the evaluation methods and representations used in the study produced valuable design feedback. With relatively small means, the procedure supports the benefits of employee participation, contributing to a safe and efficient ship design and subsequent operation.
