The amount of ergonomics and user involvement in 151 design processes
At The IEAN congress Recife, Brazil 2012, We; B.Kok, P.Vink & K. Slegers; presented our research about the use of ergonomics and user involvement in design processes.

The amount of ergonomics and user involvement in 151 design processes:
Abstract: Ergonomics, usability and user-centered design are terms that are well known among designers. Yet, products often seem to fail to meet the users’ needs, resulting in a gap between expected and experienced usability. To understand the possible causes of this gap the actions taken by the designer during the design process are studied in this paper. This can show whether and how certain actions influence the user-friendliness of the design products. The aim of this research was to understand whether ergonomic principles and methods are included in the design process, whether users are involved in this process and whether the experience of the designer (in ergonomics/user involvement) has an effect on the end product usability. In this study the design processes of 151 tangible products of students in design were analyzed. It showed that in 75% of the cases some ergonomic principles were applied. User involvement was performed in only 1/3 of the design cases. Hardly any correlation was found between the designers’ experience in ergonomic principles and the way they applied it and no correlations were found between the designers’ experience in user involvement and the users’ involvement in the design process.

Methods of the design process: an inventory
Ergonomics, usability and user-centred design are principles that are well known among designers. Yet designers often seem to fail to meet the users’ needs, designing things people don’t understand or know how to use. To have a clear view on the causes of this failure it is necessary to know what steps designers take during the design process. This research aimed to understand the methods used by designers in practice during the design process. A total of 151 design cases of students in product design were analysed.

Tools for more user friendly design: do they really improve the quality of the design?
There are many tools to improve the quality of design, jet designers often seem to fail to meet to the users’ needs, designing things people don’t completely understand, or know how to use. The aim of the research described in this paper was to understand the relationship between the design process and design tools that were used on the one hand, and the quality of the product on the other hand. In this research the design processes of students of the Master Product Design education of the Media And Design-faculty (KHLim, Belgium) are studied. This study is limited to the design of tangible products. Seventy-five design cases of student designers are studied. In this study, first, all the techniques applied the students’ design processes were listed. Second, for each case the techniques that were used were mapped. Finally the relationship between the use of those techniques and the quality of the designed product was assessed. The grades given for the product (not the process) were used as indicator for the quality of the design. 22 cases are grade by a jury (who had no knowledge of the design process) or by users. This might be perceived as a weakness (53 cases graded by the supervisors, the grades of the product could be partly influenced by the process). Since there was no significant difference in grades between the cases grade by a jury or user and the cases graded by the supervisors only, this bias is ignorable. The following categories had a positive effect on the evaluation of the product: doing a state of the art research of non-relating products; problem solving through literature study or by consulting specialists; conducting an ergonomic and functional study (study of ergonomic guidelines, performance study etc.); designing by drawing and by making tangible models; user analysis and user involvement ; gathering per group feedback; having critical attitude towards the found information and feedback. The effect of the use of design tools could not be analyses since it was only reported in two cases. Why design tools are hardly used should be studied as well as the effect of design tools on the quality of products. Furthermore research should be conducted about the strength of the correlation of each individual method as well as the correlation between the methods themselves, for these analysis more cases are needed. Using student cases instead of cases of professionals might be considered a weakness of this study because the cases do not include professional designs. However, since professional evaluations of the quality of the designs were already available and because it is difficult to obtain the design processes of professionals, these cases provided an unique opportunity to study the relationship between the methods in design process and the quality of the final product. In addition, such student cases are representative of the way young professionals work because, young designers apply the design techniques and methods they learned during their education.

Education Human Centered Design
This program offers a large curriculum covering essential steps in the user-centered design process, with attention for both hardware and software applications. The approach is practical, but also pays enough attention to the theoretical base that lies at the base of this discipline.
After attending this course you will
• have a structured insight into the design of good interfaces,
• know useful methods to design good interfaces,
• be able to apply these methods to your specific work situation,
• critically evaluate user interfaces.
The program is offered via video conference in Kortrijk and Leuven. The 14 sessions take place between February 3 and May 26, 2011. Each time from 18.00 to 21.30 hours.
This course is organized by the Postgraduate Centre of the KULeuven Campus Kortrijk and Center for User Experience Research (CUO), IBBT / KULeuven in collaboration with Flanders InShape.
