Accessibility of the Italian institutional web pages: a survey on the compliance of the Italian public administration web pages to the Stanca Act and…
2014
Accessibility of the Italian public administration web pages is ruled by the Stanca Act and in particular the Decree of the Minister issued on July 8, 2005. In this paper, an objective test is performed on the official web pages of the Italian province and region chief towns to check their compliance to the 22 technical requirements defined by the Stanca Act. A sample of 976 web pages belonging to the websites of the Italian chief towns have been downloaded in the period October---December 2012. Such a data collection has been submitted to Achecker, the worldwide recognized syntax and accessibility validation service. Several accessibility and syntax errors have been found following the aut…
Accessibility of Public Web Services: A Distant Dream?
2013
Part 1: Long and Short Papers; International audience; Today, many public services are available online through Web sites. The accessibility of the sites, also to people with disabilities, is important because the accessibility concerns equality of citizens, a cornerstone of democracy. In the current study we carried out a meta-analysis of 17 studies concerning the accessibility of the Web sites of public administration. Furthermore, we assessed the accessibility of Web pages of 12 ministries of the Finnish government. The assessments were based on the Web Content Accessibility Guidelines (WCAG). The results showed that in terms of the WCAG guidelines, the average accessibility of public We…
Evaluation of interaction metaphors for collaborative work distant immersive sites
2009
The design of the virtual environment (VE) has to take into account several factors including the input and output devices, the design of the interaction metaphor or the application domain. In addition to these considerations, the design of a collaborative virtual environment (CVE) needs to take into account the collaborative aspect of the interaction metaphor. In one hand, the interaction metaphor has to be designed for the best possible task performance. In the other hand, the influence of the interaction metaphor on the user's experience (in terms of psychological and social aspects) constitutes an important research question. To address this research question, two experimental studies h…

Identifier les conceptions de l'enseignement et de l'apprentissage pour accompagner le développement professionnel des enseignants débutants à l'univ…
2010
International audience; Les conceptions individuelles agissent comme des filtres dans la compréhension du monde environnant et, de fait, dans le développement individuel. Les enseignants universitaires ne font pas exception à la règle et leurs conceptions à propos de l'enseignement, de l'apprentissage, de ce qui aide les étudiants à apprendre ou encore des qualités associées à un bon enseignant, influencent leurs pratiques professionnelles. Cet article présente les conceptions de l'enseignement et de l'apprentissage observées chez de jeunes enseignants débutants : la diversité des conceptions et la mise en évidence que les différents profils peu-vent être associés au projet professionnel de…
Enseigner l’activité « écriture collaborative »
2019
Although certain education policies emphasize “the ability to collaborate” as a key element of educational reform, education for digital collaboration is poorly supported by public schools. To build the conditions of a sustainable education, we have developed a training model focused on learner autonomy. We present the results of an experiment conducted with students, our pedagogical model and its implementation, as well as our observation and analysis of this experiment. We analyzed discussions in instant messaging between students and teachers, and their productions. All results show the influence of our training. Thus, education and digital collaboration can be built from a triple analyt…
Cognition collective : Partage de préoccupations entre les joueurs d'une équipe de basketball au cours d'un match
2011
Resume Notre etude s’est attachee a analyser la construction de l’activite collective en s’interessant au partage des preoccupations entre les partenaires d’une equipe lors d’un match de basket-ball. Elle a ete menee en reference au cadre theorique et methodologique du cours d’action (Theureau, 2006). Elle a caracterise la nature des preoccupations individuelles des joueurs et les formes d’agencement de ces preoccupations au sein de l’equipe au cours du temps. Les resultats ont mis en evidence deux dynamiques d’apparition des moments de convergence des preoccupations en relation avec la nature de ce qui est partage par les joueurs. Sont discutees la relation entre preoccupations partagees e…
Le mérite contre la justice
2019
International audience; Le mérite a la cote. Avec lui, l'idée que chacun est responsable de ce qui lui arrive, de ses succès comme de ses échecs, et l'espérance qu'en récompensant talents et efforts, on produira une société juste et efficace.La mise en exergue constante du mérite, sans tenir compte des inégalités (sociales, de genre, d'origine, etc.), est pourtant tout sauf anodine. Elle engendre de nombreux effets pervers : à l'école, où l'idéal de la formation de tous s'efface devant la sélection des plus "méritants" ; dans le monde du travail, quand se caler sur la réussite scolaire et le diplôme amène à négliger bien d'autres talents et à créer une concurrence délétère.Sans ôter tout mé…
A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness
2018
The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…
Evaluating the user experience of omnidirectional VR walking simulators
2020
Abstract Omnidirectional treadmills (ODTs) have been traditionally proposed as a promising solution for users’ navigation in large-scale virtual environments. These mechanical devices enable users to perform locomotive motion with 360-deg freedom, while keeping their position fixed in the physical world. However, most locomotion approaches based on omnidirectional treadmills have presented either high acquisition or maintenance costs, being the capabilities of the general public, or a limited reliability. In this paper, we present a comparative usability and acceptance study with real users evaluating the two most common approaches for the development of this type of Virtual Reality (VR) wa…
