Costanza, Enrico, Panchard, Jacques, Zufferey, Guillaume, Nembrini, Julien, Freudiger, Julien, Huang, Jeffrey and Hubaux, Jean-Pierre (2010): SensorTune: a mobile auditory interface for DIY wireless sensor networks. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 2317-2326.

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 living to natural disaster prevention. WSNs can, however, be challenging to setup and maintain, reducing the potential for real-world adoption. To address this limitation, this paper introduces SensorTune, a novel mobile interface to support non-expert users in iteratively setting up a WSN. SensorTune uses non-speech audio to present to its users information regarding the connectivity of the network they are setting up, allowing them to decide how to extend it. To simplify the interpretation of the data presented, the system adopts the metaphor of tuning a consumer analog radio, a very common and well known operation. A user study was conducted in which 20 subjects setup real multi-hop networks inside a large building using a limited number of wireless nodes. Subjects repeated the task with SensorTune and with a comparable mobile GUI interface. Experimental results show a statistically significant difference in the task completion time and a clear preference of users for the auditory interface.

Lucchi, Aurlien, Jermann, Patrick, Zufferey, Guillaume and Dillenbourg, Pierre (2009): An empirical evaluation of touch and tangible interfaces for tabletop displays. In: Proceedings of the 4th International Conference on Tangible and Embedded Interaction 2009. pp. 177-184.

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 involving several actions like translation and rotation. We recruited 40 participants to take part in a user study and we present our results with a discussion on the design of touch and tangible interfaces. Our contribution is an empirical study showing that overall, the tangible interface is much faster but under certain conditions, the touch interface could gain the upper hand.

Zufferey, Guillaume, Jermann, Patrick, Do-Lenh, Son and Dillenbourg, Pierre (2009): Using augmentations as bridges from concrete to abstract representations. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 130-139.

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. Multiple External Representations are used to progressively introduce more abstract representations displayed on paper-based forms called TinkerSheets. We present the implementation of this approach on the TinkerTable, a tabletop learning environment which is used in two professional schools by four different teachers. We report observations of the use of the environment at different stages of the curriculum with first- and second-year apprentices.
