User fulfillment is gaining more attention from designers as they create or evaluate new technologies. Eudaimonic experience is a concept that highlights well-being as a component for fulfilling development. To date, it has received little attention in empirical research, especially regarding children. Although questionnaires exist to measure eudaimonic well-being in the academic context, they have primarily been used with university students. This article discusses and presents the preliminary development of a Questionnaire for measuring Eudaimonic Experiences in School (QEES). The QEES is designed to assess pupils’ eudaimonic perceptions of school activities. A sample of 360 school pupils participated in this study. The results justify the design of the QEES, as the eudaimonic well-being items developed for adults do not cover the needs of children. The QEES aims to provide new perspectives for educators and policymakers who wish to reflect on, evaluate, and promote pupils’ experiences of eudaimonia, including with technology.

This research is based on the adaptation and validation in French of the Pedestrian Receptivity Questionnaire for Fully Autonomous Vehicles (PRQF). Faced with the emergence of numerous issues related to interactions between pedestrians and fully autonomous vehicles (FAV), this questionnaire is a reliable and scientifically valid means of collecting pedestrian experiences when they cross a road in front of an autonomous vehicle. The translation methodology of the PRQF was based on a committee approach, which consisted of asking several bilingual experts to come to an agreement on a consensual translation. The validation of the French PRQF (F-PRQF) was based on the completion of 584 questionnaires. Different psychometric tests were carried out, including an accuracy analysis, a principal component factor analysis (PCA) and a confirmatory factor analysis (CFA). Our results show that the F-PQRF displays satisfactory psychometric qualities, in particular in terms of internal consistency (α = 0.932 and ω = 0.935). We also find a scale with five components, which confirms the theoretical model structure of the original scale. The F-PRQF showed good psychometric qualities, which should thus facilitate research in fully autonomous vehicles among French-speaking audiences.

While the System Usability Scale (SUS) is probably one of the most widely used questionnaires to measure the perceived ease of use of interactive systems, there is currently no scientific valid translation in French. This article describes the translation and statistical validation of the French version of the SUS, called F-SUS. On the basis of two translations carried out by a committee of bilingual experts, the various psychometric analyses made it possible to select only one translation. Fidelity measurement, factor analysis and sensitivity measurement obtained results very close or similar to the original version of the SUS. Thus, the F-SUS can be used with confidence by French-speaking usability researchers and practitioners.

Despite technological progress, daily 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.
