Acceptation des technologies [Technology Acceptance]

La question de l'acceptation des technologies se pose avec acuité au regard des modalités innovantes d'interaction, de l'essor des développements des dispositifs informatiques et des interfaces. Trois axes de recherche sont développés.1. Etude des caractéristiques individuelles, situationnelles et organisationnelles qui influencent l'appropriation des technologies et la continuité de leur usage dans différents contextes et activités humaines. 2. Etude de la charge cognitive lors de la recherche d'information sur des sites d'information en ligne, permettant d'associer les approches de l'acceptabilité opératoire et de l'acceptation sociale des technologies.3. Etude de l'expérience utilisateur (UX) lors de l'utilisation des dispositifs tactiles (multitouch) : influence des qualités ergonomiques et motivationnelles des dispositifs et des émotions engendrées lors des interactions. [Questions of technology use and acceptance are essential in today's world. The development of original and innovative computing devices has created a plethora of new interaction modes. Three research axes are developed in our research centre. 1. The study of individual, situational and organizational characteristics, which impact the technology acceptance processes. 2. The study of the users' cognitive load through the Cognitive Load Theory framework to understand how the features of an online news website influence web browsing behaviours and information retention. Our studies emphasize that the presence of multimedia content influences the amount of information retainded by users after they read online news website. Also, the presence of images related to the content of the article improves information retention, while the addition of irrelevant animations leads to a decreased performance. Moreover, our studies highlights that cognitive load can be successfully used to explain users' interactions with hypermedia, such as online newspapers. 3. The study of the user experience (UX) with multi-touch devices. By proposing an innovative perspective on the users' appraisal of new technologies, our studies aims through the study CUE-Model (Thüring & Mahlke, 2007), and the use of multi-touch devices (tablets, e.g. iPad) to measure the dynamic nature of the UX component and relationships over time in educational contexts. These researches contribute to a better understanding of the UX dynamical nature, as well as the psychological implications of multi-touch technology use, and so, will provide some useful advice to favour learners' motivations and performances.]
