For more than a decade, User Experience (UX) has grown into a core concept of Human–Computer Inter- action (HCI). Practitioners and researchers from a wide range of disciplines are daily working with this concept. However, despite many attempts to understand, define and scope UX, one may still wonder whether a consensus has been reached on this concept. In a willingness to address the complexity of this research topic and bring the concept of UX to maturity, a replication of an international survey has been conducted. The main goal of the present study is to get a better understanding of practitioners’ view- points on the notion of UX and to analyze potential evolutions over time in the understanding and prac- tical use of the concept. As both practical and theoretical implications of UX are of the greatest importance for whoever designs interactive systems, the exploration of practitioners’ perspectives is a valuable step toward continual improvement of UX activities. The present survey has been conducted amongst 758 practitioners and researchers from 35 nationalities. It allows to better understand how this concept is understood and used throughout the world. Amongst interesting results, important differences were observed according to the geographical location and background of the respondents. [less ▲]

Over the last decade, User Experience (UX) has become a core concept in the field of Human-Computer Interaction (HCI). Beyond the fact of understanding and assessing the User Experience derived from the use of interactive systems, practitioners and researchers from a wide range of disciplines are now facing the challenges of designing for User Experience. Some authors have pinpointed the existence of a gap between the theoretical knowledge developed in HCI Research and the practical knowledge actually used by designers to create rich experiences with interactive artefacts. A special focus of this paper is to translate theoretical work into experiential objects (or situations) called “Experience Triggers” [1]. Through their materiality, these artefacts bring emotions and sensations to the design process and designers can immerge into and understand the theories on experience. As a consequence of this immersion, the final product designed by the team is assumed to be more experiential. Experience Triggers are introduced here as a new tool for science-based UX design.

Many methods and tools have been proposed to assess the User Experience (UX) of interactive systems. However, while researchers have empirically studied the relevance and validity of several UX evaluation methods, few studies only have explored expert-based evaluation methods for the assessment of UX. If experts are able to assess something as complex and inherently subjective as UX, how they conduct such an evaluation and what criteria they rely on, thus remain open questions. In the present paper we report on 33 UX experts performing a UX evaluation on 4 interactive systems. We provided the experts with UX Cards, a tool based on a psychological-needs driven approach, developed to support UX Design and Evaluation. Results are encouraging and show that UX experts encountered no major issues to conduct a UX evaluation. However, significant differences exist between individual elements that experts have reported on and the overall assessment they made of the systems. [less ▲]

The breadth and scale of multimedia archives provides a tremendous potential for historical research that hasn't been fully tapped up to know. In this paper we want to discuss the approach taken by the History of Europe application, a demonstrator for the integration of human and machine computation that combines the power of face recognition technology with two distinctively different crowd-sourcing approaches to compute co-occurrences of persons in historical image sets. These co-occurrences are turned into a social graph that connects persons with each other and positions them, through information about the date and location of recording, in time and space. The resulting visualization of the graph as well as analytical tools can help historians to find new impulses for research and to un-earth previously unknown relationships. As such the integration of human expertise and machine computation enables a new class of applications for the exploration of multimedia archives with significant potential for the digital humanities. © 2014 Springer-Verlag.

Depuis une dizaine d’années, le concept d’expérience utilisateur (UX) se répand dans le domaine des Interactions Homme-Machine (IHM). Centré sur l’utilisateur et son expérience subjective vécue de l’interaction avec un système interactif, l’UX s’intéresse, entre autres, aux aspects émotionnels, hédoniques ou encore esthétiques composant l’interaction. Cependant, bien que déjà très utilisé par les professionnels, ce concept souffre notamment d’un manque de recherche empirique. De plus, de nombreuses définitions et perspectives sur l’UX cohabitent sans donner lieu à un consensus scientifique clair. Or, pour progresser dans ce champ de recherche, l’enseigner, ou pour communiquer sur celui-ci, il est nécessaire de mieux le comprendre et le délimiter. Une enquête par questionnaire (adaptée de Law et al., 2009) réalisée sur 758 professionnels et chercheurs de plus de 35 nationalités permet de mieux comprendre comment ce concept est compris et utilisé à travers le monde. Les résultats montrent des divergences entre les profils des participants. [less ▲]

In order to study how the notion of User Experience (UX) evolved over the last few years, an international survey originally conducted in 2008 by Law et al. [1] has been replicated. Its main goal was to get some insights on the points of view from practitioners on the notion of UX. After having slightly adapted the initial (English) survey and having translated it into French and German, more than 758 valid answers have been collected from all over the world. This experience report aims at illustrating some of the challenges involved in the replication of such a study as well as successes and limitations. [less ▲]

Keeping a diary is not just a hobby undertaken by teenage girls trying to make sense of life and love. Diary methods have been widely used in medical research where patients are asked to keep a diary during a clinical trial or disease treatment. In Human-Computer Interaction, a diary study is a qualitative technique for collecting data on what users have done or experienced. Much like a travel journal contains descriptions of the traveler’s experiences, a UX diary contains descriptions of the user’s experiences with a system. What kind of UX research questions could diaries help answer? Depending on the design of your diary study, you may get information on the overall impression of a specific device, usage of features, technological acceptance, emotions associated with task performance, or learnability of an application. Of course you could also get this information with a survey, an interview, or a user test. But only diary methods will give you access to temporal and longitudinal information gathered in a natural context of the interaction. [less ▲]

This paper presents the results of an ergonomic intervention conducted within a blast furnace plant. As part of its risk prevention program, the company decided to set up an action plan, in a participatory manner, by setting up working groups to solve health & safety issues. This field mission involved 230 employees, 80 of whom participated actively by being incorporated into working groups. After four months of intervention, a questionnaire survey has been conducted among employees to study the effects of participation on the safety climate. The results seem promising and show that the benefits of participation are numerous: a more positive safety climate associated to safer attitudes and behaviors. However, rather than just participa- tion, it seems to be the employee involvement in the working groups and the satisfaction they derive from their participation that guarantee these positive results. Hence, participatory ergonomics seems to be an effective way to decrease the number of unsafe behaviors at work, provided that the type of participation has been previously well defined and organized according to the specific context of each organization.

Despite technological progress, dailies Human-Computer Interactions (HCI) are still encompassing moments where the interaction between the user and the system is temporarily interrupted (file download, setup of a program, etc.). These waiting times are often sources of anxiety and irritation. In order to enhance the User eXperience (UX) during waiting time in HCI, this research based on cognitive models of time perception focuses on the impact of several variables on the satisfaction and waiting time perceived by a user. Variations in waiting time duration, cognitive workload and informational level of a feedback screen are therefore experimentally created to study their impact on satisfaction and waiting time perception. The results confirm the existence of a link between cognitive workload and waiting time perception and may provide valuable information for User Interface design. [less ▲]

This research focuses on the satisfaction and waiting times perceived by a user during the moments where the interaction between the user and the system is temporarily interrupted (file download, setup of a program, etc.). These waiting times are often sources of anxiety and irritation. They go usually with the presentation of an animated progress bar. The objective of this research is to study the impact of different variable-rate progress bars by varying the speed of scrolling. Thus, we are interested in the effects of acceleration and deceleration between progress bars positions. The results confirm the existence of a causal link between perception of waiting time and satisfaction. In addition, a progress bar with a decelerating speed is significantly more appreciated by the users. The results may provide valuable information for the design of computer interfaces. [less ▲]

Even though the benefits of usability have widely been proven, it seems that development-oriented companies face many difficulties to introduce usability practices into their defined development processes. This paper describes the overall methodology deployed as an attempt to achieve a closer integration of usability practices in the software development process. Model-Driven Engineering (MDE) is used as a basis for this integration. Providing a precise framework composed of models and transformations, it allows to track usability problems and to highlight where exactly they occur in the development process. We will thus be able to link every step of the process to specific ergonomic inputs and to study their consequences on the usability of the generated system. Because MDE will only be used as a way among others to investigate some hypotheses on usability and User-Centered Design (UCD) in general, our results are expected to provide valuable and generic information on usability and UCD processes.

Cette communication présente les résultats d’une intervention d’ergonomie participative menée en milieu industriel au sein d’une usine d’un grand groupe sidérurgique. Dans le cadre de son programme de prévention des risques, cette entreprise participe chaque année à un challenge santé-sécurité consistant à mettre en place un programme d’actions sur une année et ce, de manière participative en créant des groupes de travail. Après quatre mois d’intervention, une enquête par questionnaire a été réalisée auprès des salariés du secteur impliqué afin d’étudier les impacts de la participation sur la culture de sécurité. Les résultats semblent prometteurs et montrent que les bénéfices de la participation sont multiples : un climat de sécurité plus positif et des attitudes et comportements plus sécuritaires. Cependant, plus que la simple participation, ce sont bien plutôt l’implication des employés dans le challenge et la satisfaction qu’ils en retirent qui garantissent ces effets positifs. [less ▲]

otre étude vise à répondre à une demande de la bibliothèque universitaire de Metz (accueillant 15 000 étudiants) concernant la réorganisation du système signalétique en place. Ce dernier est obsolète et insuffisant et ne répond pas aux besoins d’orientation et d’information des usagers. En effet, la signalétique actuelle, créée par un imprimeur en 1998, a été pensée en cohérence avec la signalétique extérieure du campus universitaire, sans toutefois faire l’objet d’une étude préalable des besoins. De plus, son manque de modularité, défaut fréquent des systèmes signalétiques, a conduit à une inadaptation rapide. L’importance de notre étude réside dans les multiples enjeux mis en lumière par l’installation d’une signalétique adaptée dans un lieu d’accueil du grand public. On constate que, pour certains auteurs, l’étude de la signalétique est une « discipline à part entière, dont les recherches s’inscrivent dans le prolongement de celles de l’architecture » [7, p. 244]. On pourrait alors se demander quelles fonctions peuvent avoir la psychologie et l’ergonomie dans ce domaine d’application. La réponse est qu’en fait, ces disciplines vont appréhender la problématique de la signalétique en tenant compte à la fois des aspects techniques et architecturaux, mais également en analysant les comportements, besoins et stratégies d’information des usagers. Elles permettent donc d’apporter des réponses concrètes relatives aux problèmes en matière de signalétique. Les objectifs de notre étude, au vu de la demande qui nous a été adressée par la direction de la bibliothèque, sont doubles : d’une part, établir une typologie des usagers de la bibliothèque ; d’autre part, dans un second temps, établir, à partir des observations des comportements et des problèmes rencontrés, une liste de recommandations concrètes en vue de la mise en place d’une nouvelle signalétique. Sur ce dernier point, les questions soulevées par notre problématique peuvent se résumer de la manière suivante : où mettre des indications signalétiques ? Quel contenu y intégrer ? Et sous quelle forme les présenter ? [less ▲]

Our study deals with the ergonomic reorganization of the signage of a university library. Within this framework, this research leans on three theoritical fields : environmental psychology, information and communication sciences, and cognitive ergonomics. To demonstrate that a good usability of the signage would support user’s orientation and appropriation of the place, interviews, questionnaires and a user test were carried out. The results, in agreement with the hypothesis, aims first at developping applied prospects as the concrete reorganization of the sign system, and also theoritical prospects of enrichment of theoritical models and a better knowledge of the user’s behaviors and strategies.
