On Legitimacy: Designer as minor scientist

User experience research has recently been characterized in two camps, model-based and design-based, with contrasting approaches to measurement and evaluation. This paper argues that the two positions can be constructed in terms of Deleuze & Guattari’s “royal science” and “minor science”. It is argued that the “reinvention” of cultural probes is an example of a minor scientific methodology reconceptualised as a royal scientific “technology”. The distinction between royal and minor science provides insights into the nature of legitimacy within

Interplay between User Experience (UX) evaluation and system development

User Experience (UX) is a maturing research area pertaining to as well as extending beyond the traditional usability. Issues in the realm of usability may be amplified in UX because of its larger scope. Four key non-orthogonal issues are definition, modeling, method selection, and interplay between evaluation and development. Leveraging the legacy of a series of related research activities, this Special Issue (SI) aims to develop a deeper understanding of how evaluation feedback shapes software development, especially when experiential qualities such as fun, trust, esthetic values are concerned. Three articles addressing this specific topic from different perspectives and with different approaches are included in this SI.Law, EL.; Abrahao Gonzales, SM. (2014). Interplay between User Experience (UX) evaluation and system development. International Journal of Human-Computer Studies. 72(6):523-525. doi:10.1016/j.ijhcs.2014.03.003S52352572

Anticipating user eXperience with a desired product: The AUX framework

Positive user experience (UX) has become a key factor in designing interactive products. It acts as a differentiator which can determine a product’s success on the mature market. However, current UX frameworks and methods do not fully support the early stages of product design and development. During these phases, assessment of UX is challenging as no actual user-product interaction can be tested. This qualitative study investigated anticipated user experience (AUX) to address this problem. Using the co-discovery method, participants were asked to imagine a desired product, anticipate experiences with it, and discuss their views with another participant. Fourteen sub-categories emerged from the data, and relationships among them were defined through co-occurrence analysis. These data formed the basis of the AUX framework which consists of two networks which elucidate 1) how users imagine a desired product and 2) how they anticipate positive experiences with that product. Through this AUX framework, important factors in the process of imagining future products and experiences were learnt, including the way in which these factors interrelate. Focusing on and exploring each component of the two networks in the framework will allow designers to obtain a deeper understanding of the required pragmatic and hedonic qualities of product, intended uses of product, user characteristics, potential contexts of experience, and anticipated emotions embedded within the experience. This understanding, in turn, will help designers to better foresee users’ underlying needs and to focus on the most important aspects of their positive experience. Therefore, the use of the AUX framework in the early stages of product development will contribute to the design for pleasurable UX

Tuning an HCI Curriculum for Master Students to Address Interactive Critical Systems Aspects

International audienceThis paper presents the need for specific curricula in order to address the training of specialists in the area of Interactive Critical Systems. Indeed, while curricula are usually built in order to produce specialists in one discipline (e.g. computer science) dealing with systems or products requires training in multiple disciplines. The area of Interactive Critical Systems requires deep knowledge in computer science, dependability, Human-Computer Interaction and safety engineering. We report in this paper how these various disciplines have been integrated in a master program at Université Toulouse III, France and highlight the carrier paths followed by the graduated students and how these carriers are oriented towards aeronautics and space application domains

Contextual user research methods for eliciting user experience insights in workplace studies

Purpose: The purpose of this paper is to contribute with experiences and reflections on user research methods that we have tested in our studies of users\u27 experiences in office environments. Theory: Previous workplace studies with qualitative data approaches mainly rely on traditional methods such as interviews and observations. Based on user-centered design research, we outline methods that can be used to facilitate understanding the interrelations between users and their surrounding environment. Design: Three methods and their variations were applied in different case studies to facilitate understanding of user experiences in office environments: (i) spatial walkthroughs, (ii) card sorting, and (iii) experience curve mapping. Findings: Spatial walkthroughs were more immersive and provided most insights on the actual context with respect to spatial design qualities. The card sorting enabled exploring user experiences with respect to predetermined aspects. The experience curve mapping enabled understanding the temporal aspects of the user experience. The latter two methods were less immersive and less disruptive in the organisational context than the spatial walkthroughs. The flexibility of these methods allows for tailoring the application depending on the purpose of the workplace studies. We recommend using a combination of these methods to capture a more holistic understanding of user experiences and improving the workspace design to better fit the users. Originality: The outlined methods required user involvement and participation and provided insights for making evidence-based recommendations for designing or redesigning office environments that fit users\u27 needs and preferences

Micro-\u3cem\u3eMeso\u3c/em\u3e-Macro Comparative Law: An Essay on the Methodology of Comparative Law

There are strong analogies between the quest for a methodology of comparative law and the broader debate on the epistemology of social and natural sciences. In this vein, after having explored the dispute between holists and reductionists, I argue that the dichotomy between micro and macro comparative law ought to be abandoned. Building on the insights of social theory, I introduce a specific framework to bridge the two levels of enquiry through a meso analysis. This framework is applied to investigate the robustness of the findings of the legal origin theory

The evolution of the usability concept as an indicator of software quality

Technological advances in the field of information and interactive systems mean that increasing numbers of factors and criteria are considered to assess quality during the design, development and evaluation process. In this context, concepts such as quality of use and user experience have appeared and in many cases are replacing or supplementing existing usability properties to identify the quality of the interaction process. In this paper we describe and analyze the evolution of the different concepts to identify the quality of the interaction on information systems and we help to characterize and locate each quality factor in one dimension and a specific range of the process of use, and consider the relationships and overlap between these concepts

Identifying user experience dimensions for mobile incident reporting in urban contexts

International audienceDespite the increasing interests raised by incident reporting systems, it is still unclear what dimensions of user experience (UX) and other contextual factors should be taken into account for the various stages of declaring an incident using mobile-phone applications. Research questions: How do citizens perceive and describe urban incidents? What UX dimensions are important for reporting an incident with a mobile-phone application? What other (contextual) factors are important from the users' point of view when declaring incidents? Which of the UX dimensions and contextual factors are important when in the various phases during an incident declaration? Literature review: Overall, there is a lack of empirical research in the domain of incident reporting. In general, the UX dimensions—visual and aesthetic experience, emotion, stimulation, identification, meaning and value, and social relatedness/coexperience—are important when designing interactive systems. It also shows that incidents are related to the citizen's perception of the environment. Methodology: A triangulated method approach combining interviews, a survey of existing systems, and a model-based task analysis were applied. This allows us to present a generic task model for incident reporting with a detailed description of UX dimensions affected in the various subtasks. Results and conclusions: Our findings point out the effect of UX dimensions in the task engaged by users when reporting urban citizens. The overall UX is directly influenced by the perceived level of severity, inconvenience and involvement, the personal context, and the technological mobile context. We have found that while several UX dimensions are highly relevant, they are not equally distributed along the several subtasks that citizens engage when reporting incidents. This study shows that semistructured requirement interviews can provide information about UX dimensions and it highlights the importance of the identification of UX dimensions in early phases of the development process
