SensorTune: a Mobile Auditory Interface for DIY Wireless Sensor Networks

Jean-Pierre Hubaux, Jeffrey Huang, Julien Freudiger, Guillaume Zufferey, Jacques Panchard, Enrico Costanza

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 ...

Task Performance vs. Learning Outcomes: A Study of Tangible User Interface in Classroom Setting

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey, Sébastien Cuendet

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 ...

An empirical evaluation of touch and tangible interfaces for tabletop displays

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey, Aurélien Lucchi

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 ...

Using Augmentations as Bridges from Concrete to Abstract Representations

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey

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 ...

TinkerSheets: Using Paper Forms to Control and Visualize Tangible Simulations

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey, Aurélien Lucchi

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 ...

A Tabletop Learning Environment for Logistics Assistants: Activating Teachers

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey

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 ...

Hardware/Software Coevolution of Genome Programs and Cellular Processors

Pierre-André Mudry, Guillaume Zufferey

The application of evolutionary techniques to the design of custom processing elements bears a strong relation to the natural process that led to the co-evolution of cells and genomes in biological organisms. As such, it is an interesting avenue for an eff ...

A Dynamically Constrained Genetic Algorithm For Hardware-software Partitioning

Pierre-André Mudry, Guillaume Zufferey

In this article, we describe the application of an enhanced genetic algorithm to the problem of hardware-software codesign. Starting from a source code written in a high-level language our algorithm determines, using a dynamically-weighted fitness function ...

A hybrid genetic algorithm for constrained hardware- software partitioning

Pierre-André Mudry, Guillaume Zufferey

In this article, we propose a novel partitioning method for hardware-software codesign based on a genetic algorithm that has been enhanced for this specific task. Given a high- level program and an area constraint, our software considers different granular ...
