Designing for Positive User Experience in Work Contexts: Experience Categories and their Applications
2018
Experience categories describe repeatedly occurring qualities of positive experiences that can be used for the analysis and generation of new/further/more positive experiences. This paper describes experience categories for the workplace. Based on 345 reports of positive user experiences in the workplace, we identified 17 experience categories through qualitative content analysis and describe their necessary and optional attributes. We believe that experience categories can support analysis and design activities for the work place in three ways: (a) using the questions derived from experience interviews to analyze existing positive experiences in work contexts, (b) explaining the potential …
Factory Workers' Ordinary User Experiences: An Overlooked Perspective
2018
Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people’s mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people’s attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers’ everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and ho…
A Nonlinear Control of Synchronous Reluctance Motors (SynRM) Based on Feedback Linearization Considering the Self and Cross-Saturation Effects
2019
This paper proposes a nonlinear controller based on feedback linearization for Synchronous Reluctance Motors (SynRM) drives that takes into consideration the self and cross-saturation effects. Such control technique permits the dynamics of both the speed and flux loops to be maintained constant independently from the load and the saturation of the iron core. The proposed technique has been tested experimentally on a suitably developed test set-up.
Features of W production in p-p, p-Pb and Pb-Pb collisions
2017
We consider the production of inclusive W bosons in variety of high-energy hadronic collisions: p--p, p--$\overline{\rm p}$, p--Pb, and Pb--Pb. In particular, we focus on the resulting distributions of charged leptons from W decay that can be measured with relatively low backgrounds. The leading-order expressions within the collinearly factorized QCD indicate that the center-of-mass energy dependence at forward/backward rapidities should be well approximated by a simple power law. The scaling exponent is related to the small-$x$ behaviour of the quark distributions, which is largely driven by the parton evolution. An interesting consequence is the simple scaling law for the lepton charge as…
Aesthetic Appeal and Visual Usability in Four Icon Design Eras
2016
Technological artefacts express time periods in their visual design. Due time, visual culture changes and thus affects the design of pictorial representations in technological products, such as icons in user interfaces. Previous research of temporal aspects in human-computer interaction has been focusing on particular interaction situations, but not on the effects of design eras on user experience. The influence of icon design styles of different eras on aesthetic and usability experiences was studied with the method of primed product comparisons. Affective preferences and their processing times were analysed in order to examine visual usability in terms of semantic distance and aesthetic a…
« Le pilotage par l’Etat de la formation des enseignants du début des années 1990 à nos jours et ses incidences sur le métier de formateur »
2014
L’objet de cet article est de questionner, dans une perspective historique, la manière dont l’État a organisé et a fait évoluer la formation des enseignants du début des années 1990 à nos jours. Il s’attache à mettre en lumière les ambitions qui ont présidé aux réformes et tente de montrer la manière dont le métier de formateur d’enseignants s’est constitué et a évolué. Le formateur avait acquis un certain nombre de savoir-faire, et plus généralement une certaine culture, qui pourraient conduire à affirmer qu’un processus de professionnalisation était en cours, et ce jusqu’au milieu des années 2000. Ce processus tendait à rassembler sous une même dénomination, celle de « formateur », des in…
Evaluating the Authenticity of Virtual Environments: Comparison of Three Devices
2016
Immersive virtual environments (VEs) have the potential to provide novel cost effective ways for evaluating not only new environments and usability scenarios, but also potential user experiences. To achieve this, VEs must be adequately realistic. The level of perceived authenticity can be ascertained by measuring the levels of immersion people experience in their VE interactions. In this paper the degree of authenticity is measured via anauthenticity indexin relation to three different immersive virtual environment devices. These devices include (1) a headband, (2) 3D glasses, and (3) a head-mounted display (HMD). A quick scale for measuring immersion, feeling of control, and simulator sick…
Assisting immersive virtual reality development with user experience design approach
2017
In our study we explored how to design a biography of a late Finnish artist as a VR experience. We conducted a development process assisted by user experience (UX) design methods, which increased the process efficiency, and resulted in a research prototype. Through previous research and our development process, we identified components affecting the user experience. These components are: Immersion, Presence, Disorientation, Sense of Control, Pleasantness, Exploration and Simulator Sickness. From our user study with 13 participants, we were able to draw implications that relate to these components. While the set of components could be incomplete or subject to change, shows that further resea…
Actual and Potential Pedagogical Use of Tablets in Schools
2013
This study reviews the potential of tablet technology for teaching and learning. In autumn 2012, we conducted a focused survey comprising quantitative and qualitative questions with Finnish teachers (N = 171, from 54 schools). We focused on perceived pedagogical opportunities and the actualized pedagogical potential of tablets at schools. The survey results indicate that the actual usefulness of tablets in schools was significantly less than what teachers perceived as the pedagogical potential. However, the results demonstrate the positive impact these devices are having on teaching and learning, as well as prompting changes in pedagogical perspectives. Teachers stated that tablets can dive…
Connaissances et compétences motrices en sport collectif : quoi enseigner ?
2019
Cet article de synthèse s’inscrit dans la rubrique « Innovations objectivées » de la revue eJRIEPS. Son objectif est de présenter et d’analyser les connaissances en sports collectifs qui pourraient être enseignées à l'école et dans une approche compatibles avec l'horaire en lycée et en collège. Une première expérimentation au lycée de Thala en Tunisie a permis de fournir une première indication sur la pertinence des catégories retenues. A la lumière de cette expérimentation, les contenus des programmes français 2008, 2010 et 2016 en EPS sur l’enseignement des sports collectifs sont analysés et examinés en regard des connaissances proposées. This synthesis article fits in « Innovations » sec…
