Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

We investigated the role that tangibility plays in a problem-solving task by observing logistic apprentices using either a multitouch or a tangible interface. Results showed that tangibility helped them perform the task better and achieve a higher learning ...

We describe a tabletop environment used in vocational schools to teach theoretical concepts to apprentices in lo gistics through the use of a small-scale model of a ware house. It provides a Tangible User Interface in the form of wooden shelves, metallic p ...

Tabletop systems have become quite popular in recent years, during which there was considerable enthusiasm for the development of new interfaces. In this paper, we establish a comparison between touch and tangible interfaces. We set up an experiment involv ...

Tangible User Interfaces (TUIs) offer the potential to facilitate collaborative learning in new ways. This paper presents an empirical study that investigated the effects of a TUE in a classroom setting on task performance and learning outcomes. In the tan ...

This paper describes a promising methodology for studying co-located groups: mobile eye-trackers. We provide a comprehensive description of our data collection and analysis processes so that other researchers can take advantage of this cutting-edge technol ...

We describe a pedagogical approach supporting the acquisition of abstraction skills by apprentices in logistics. Apprentices start with a concrete representation in the form of a small-scale model which aims at engaging them in learning activities. Multipl ...

Wireless Sensor Networks (WSNs) allow the monitoring of activity or environmental conditions over a large area, from homes to industrial plants, from agriculture fields to forests and glaciers. They can support a variety of applications, from assisted livi ...

: Prior work has successfully described how low and high-performing dyads of students differ in terms of their visual synchronization (e.g., Barron, 2000; Jermann, Mullins, Nuessli & Dillenbourg, 2011). But there is far less work analyzing the diversity of ...

Research suggests that massive open online course (MOOC) students prefer to study in groups, and that social facilitation within the study groups may render the learning of difficult concepts a pleasing experience. We report on a longitudinal study that in ...

This paper describes TinkerSheets, a paper-based interface to tangible simulations. The proposed interface combines the advantages of form-based input and paper. Form-based input allows to set an arbitrary number of parameters. Using paper as a medium for ...

Study groups are common approaches for students to study together at schools. However, little is known about how this approach is suited to MOOC based learning, where learners watch and discuss MOOC lecture videos in a collaborative manner. Watching MOOCs ...

We analyze classroom orchestration as a question of usability in which the classroom is the user. Our experiments revealed design features that reduce the global orchestration load. According to our studies in vocational schools, paper-based interfaces hav ...
