Classroom orchestration : The third circle of usability
Graph Chatbot
Chattez avec Graph Search
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.
This paper addresses the End-to-End Quality of Service (QoS) guarantees and control for multimedia content delivery over heterogeneous networks, with a particular focus on end user terminal perspective. We design and implement a multimedia terminal which c ...
We propose a novel critiquing-based recommender interface, the hybrid critiquing interface that integrates the user self-motivated critiquing facility to compensate for the limitations of system-proposed critiques. The results from our user study show that ...

Online systems that help users select the most preferential item from a large electronic catalog are known as product search and recommender systems. Evaluation of various proposed technologies is essential for further development in this area. This paper ...
The articulation of practice and theory is a central problematic in a dual apprenticeship system that combines working in a company and attending courses at school. Design problems are proposed by teachers as a way to address theoretical concepts in a prac ...
Heliodons aid the building design process by allowing the simulation of different solar angles with respect to physical scale models. At MIT, two different variations of this setup are being developed. The first one consists of a small, portable heliodon t ...
This paper presents a new Procedural Analog Design tool called PAD. It is a chart-based design environment dedicated to the design of analog circuits aiming to optimise design and quality by finding good tradeoffs. This interactive tool allows step-by-step ...
We present a receiver design for joint interference suppression and
equalization of asynchronous multi–user space–time block coded (STBC) systems. We describe the design of front end prefilters to synchronize the received blocks from all users. Simulation ...
The role of evaluation in software development has been well established. It is of first importance in usability engineering. Over the last years, many interactive systems have benefited from user evaluation, including e- learning applications. As with oth ...
This paper proposes a number of enhancements to UML's Object Constraint Language to improve its usability for specifying operations by pre- and postconditions. In particular, we propose notational shortcuts and semantic modifications to OCL so that it can ...
