Cet article décrit une interface de navigation par survol dans une reconstitution urbaine numérique en 3D de plan relief. Cette navigation s'effectue en utilisant la métaphore de l'avion mimé à partir d'une main libre de tout dispositif physique, et dont l'acquisition de sa position et de son orientation se font à partir d'un périphérique de repérage et de suivi 3D. Ce mode de navigation a été mis en place dans le cadre d'une valorisation grand public du plan relief de la ville de Verdun en Meuse, France (maquette à l'échelle 1/600 e). Deux évaluations ergonomiques ont été menées afin d'évaluer ce type d'interface, d'en révéler ses défauts, et d'en gommer certains. Des perspectives de solutions sont abordées concernant les défauts restants.
This article presents a web-based toolset, the process leading to its design as well as its experimentation with real users. This device uses synchronous speech transcription to provide students with a textual version of the teacher's speech during class, as well as offering different functionalities. The goal of this instrumentation is to explore the potential of synchronous transcription in classes.
This paper presents the ongoing conception of a set of tools, based on live transcription of speech during lectures and designed to instrument traditional lectures as well as web conferences or hybrid learning situations. The toolset exploits speech and interactions taking place during courses, keeps track of them and facilitates their reuse both in students' studies and in future iterations of the course delivered by the teacher. Its goal is to help students stay focused on the teacher's explanations and offer them greater possibilities of interactions. The prototype was conceived with an approach based on the analysis of communicational and informational needs of the end users, especially in regard to the instrumentation possibilities offered by the innovative technologies considered in the project. In this paper, we detail the different tools produced in order to offer synchronous and asynchronous support to the learning activity. We describe a real-life test as well as changes brought to the device afterwards, and finally we describe the first experiment conducted with the device.
