Abstract: Being in a context of great transformations of the whole system company-product-market, design becomes interpreter of the society and strategic key-point for production realities. Design must assume an ergonomic approach and a methodology oriented to product innovation where people are the main focus of the system. Today it is visible the need for a methodological approach able to include the context of use employing user’s “creative skills”. In this scenario, a design educational model based only on knowledge doesn’t seem to be fulfilling; the traditional “deductive” method doesn’t meet the needs of new productive assets, here the urgency to experiment …within the “inductive” method for the development of a method where to know and to know how, theory and practice, act synergistically. The aim is to teach a method able to help a young designer to understand people’s needs and desires considering both the concrete/cognitive level and the emotional level. The paper presents, through some case studies, an educational model developed combining theoretical/conceptual and practical/applicatory aspects with user experiential aspects. The proposed approach to design enables the students to investigate users’ needs and desires and helps them proposing innovative ideas and projects better fitting today’s market realities. Show more

Abstract: This paper presents a case study of the application of user centered design methodologies in the product development for a line of ergonomic office furniture. The study aimed to analyze the experience of using a workstation from the perspective of two groups of users, installers and end users. The observation of users in their natural context of use not only allowed the development team to identify key needs and strategies of the users, transforming them into design solutions, but mainly it warned them of the importance and impact of user involvement in the product development cycle.

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.

Abstract: Citizens are increasingly called upon to comment on issues that directly concern them. However, such consultations may be tokenistic [1] as they occur with limited respondents, or may be at a time, or in a format which is inconvenient to the user. To encourage wider participation, the VoiceYourView project (vYv) has developed a system allowing people to make comments in a manner, time and place convenient to them. A real world trial of the prototype system was conducted at Coventry University campus to explore issues related to the system’s usability and usage, as a means of enabling campus users to …comment on their environment. Members of the university population were invited to comment on the university estate using one of five technologies (e-mail, online form, iPhone app, SMS message, or electronic kiosk). Although the immediate application area in this case was the design of public spaces, the approach can be transferred to other domains and thus provide a new way of gathering user information. Submitted comments were automatically analysed in terms of theme, sentiment, location and actionability and displayed online in a 2D visualisation. It is argued that that online data collection (crowd sourcing and skimming social networks) may provide a rich source of information for future ergonomists. Show more

Abstract: The consumer products generation is one of the main engines that fuel the planet’s environmental problems, reductionof environmental impacts associated with the products has been studied from various aspects between them, the supply of products for public consumption instead of private, seeking to meet the needs of the community by establishing programs for sharing single product. It has been detected a problematic issues linked to this strategy, where the user acceptance of this new way of living together with the products must be achieved. The arguments here presented seek to identify user perception of such proposals and their possible acceptance …throughout strategies from the User Centered Design (UCD). Show more

Abstract: The Design for Usability project aims at improving the usability of electronic professional and consumer products by creating new methodology and methods for user-centred product development, which are feasible to apply in practice. The project was focused on 5 key areas: (i) design methodology, expanding the existing approach of scenario-based design to incorporate the interaction between product design, user characteristics, and user behaviour; (ii) company processes, barriers and enablers for usability in practice; (iii) user characteristics in relation to types of products and use-situations; (iv) usability decision-making; and (v) product impact on user behaviour. The project team developed methods and …techniques in each of these areas to support the design of products with a high level of usability. This paper brings together and summarizes the findings.

Abstract: The process of product development has received special attention as it is being recognized as a source of competitive gain. Through its systematic use companies reduce costs, increase quality and decrease development time. However, one can find products being launched on the market that cause dissatisfaction to its users, and in consequence if the customer feels harmed or injured he will no longer purchase a product from the same brand. This in regard only to the commercial aspect; usually the danger of an accident or injury is not even thought about. This paper is the basis of the dissertation master’s …degree and used a literature research to build the repertoire, analyzing the methodologies applied by product design engineers, designers and ergonomists. The analysis results demonstrate the inefficiency of the design methodologies ergonomic issues. The contribution of this work lies in the suggestion to include ergonomic tools in all phases of product development and the presentation of a table with the tools that points out its most suitable time of application and results.

Abstract: This study supports itself in ergonomic concepts and usability criteria by prioritizing the identification and correction of problems found during the interaction of children with projected interfaces for them and left from the cognitive, interactional and interfacial difficulties caused by the excesses of color, elements and animation in sites and games, between them the difficulty of recognition of the information during the interaction with the elements of grid of the interface. The results of the methodology had proven that 78.38% of the 37 children got so absorbed by the game and forgot to fulfill their tasks, at least partially, and …that the application of the supported ergonomic beddings in usability criteria is imperative. It is relevant to point out that the projetual activity of the game is centered in the user, the child, whose behavior is distinct and particular. Points that had been disclosed that had passed unobserved by the involved adults in this project, and that they had displayed the unappropriateness of some screens of the Spore® to the etária band due to the ambiguity of the game, besides, the children had been sensible to the clarity in some screens and had passed for unnecessary situations of stress.

Abstract: This article sets out to discuss the results of evaluations of usability made by children, teachers and designers through methods targeted on their profiles and contexts of use. Based on a survey of methods for evaluating usability, a field study was conducted in which such users - stakeholders - explored the educational software called "Mundo da Criança" (“Child’s World”). The focus of this study was the analysis of this system and principally of the appropriateness of methods as to the avenues they suggest such users and contexts might explore.

Abstract: The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative. These systems, also known as LMS (Learning Management Systems), can be classified according to their educational goals …and their technological features. However, in these systems the usability issues are related with the relationship/interactions between user and system in the user’s context. This review is a synthesis of research project about Information Ergonomics and embraces three dimensions, namely the methods, models and frameworks that have been applied to evaluate LMS. The study also includes the main usability criteria and heuristics used. The obtained results show a notorious change in the paradigms of usability, with which it will be possible to discuss about the studies carried out by different researchers that were focused on usability ergonomic principles aimed at E-learning.
