HURTER, Christophe, Lesbordes, Rmi, Letondal, Catherine, Vinot, Jean-Luc and Conversy, Stephane (2012): Strip'TIC: exploring augmented paper strips for air traffic controllers. In: Proceedings of the 2012 International Conference on Advanced Visual Interfaces 2012. pp. 225-232.

The current environment used by French air traffic controllers mixes digital visualization such as radar screens and tangible artifacts such as paper strips. Tangible artifacts do not allow controllers to update the system with the instructions they give to pilots. Previous attempts at replacing them in France failed to prove efficient. This paper is an engineering paper that describes Strip'TIC, a novel system for ATC that mixes augmented paper and digital pen, vision-based tracking and augmented rear and front projection. The system is now working and has enabled us to run workshops with actual controllers to study the role of writing and tangibility in ATC. We describe the system and solutions to technical challenges due to mixing competing technologies.

HURTER, Christophe, Edouard, Paul, Gaits, Vincent, Nadfaoui, Hasna, Pailler, Jrome, Letondal, Catherine and Conversy, Stephane (2011): Etude exploratoire du stylo électronique pour le Contrôle Arien. In: Proceedings of the 2011 Conference of the Association Francophone dInteraction Homme-Machine 2011. p. 15.

Current environment used by air traffic controllers mixes digital visualizations (radar screen), and tangible systems with paper strip. Despite the fact that paper strip are robust, flexible and complementary to the radar screen, authorities decided to abandon it in the profit of digital strip. The main issue of paper strip is that the system does not have access to the information written on it. In this paper, we studied an alternative solution with hybrids Anoto pens with contiuous streaming. We first retrieved important tasks performed by air traffic controller, second, we investigated to find out efficient interaction paradigm for their activity. Finally, we developed and assessed an operational prototype with new functionalities. This suggests that it is possible to retain advantages of existing paper strip while informing informatics systems and improving interaction.

Letondal, Catherine, Chatty, Stephane, Phillips, Greg, Andr, Fabien and Conversy, Stephane (2010): Usability requirements for interaction-oriented development tools. In: Lawrance, Joey and Bellamy, Rachel (eds.) Proceedings of the 22nd Annual Workshop of the Psychology of Programming Interest Group PPIG 2010, Sep 2010 19th-21st Sep, 2010, University Carlos III of Madrid, Legans, Spain. pp. 12-26.

Building interactive software is a notoriously complex task, for which many programming tools have been proposed over the years. Although the research community has sporadically identified usability requirements for such tools, tool proponents rarely document their design processes and there is no established reference for comparing tools with requirements. Furthermore, the design of most tools is strongly influenced by the design of their underlying general purpose programming languages. These in turn were designed from their own set of little-documented requirements, which adds to the confusion. In this paper, we provide a review and classification of the requirements and properties expected of interactive development tools. We review how designers of APIs and toolkits for interaction-oriented systems set the usability requirements for the programming interface of their systems. We relate our analysis to other studies in related domains such as end-user programming, natural programming, and teaching.

Tsandilas, Theophanis, Letondal, Catherine and Mackay, Wendy E. (2009): Musink: composing music through augmented drawing. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 819-828.

We focus on the creative use of paper in the music composition process, particularly the interaction between paper and end-user programming. When expressing musical ideas, composers draw in a precise way, not just sketch. Working in close collaboration with composers, we designed Musink to provide them with a smooth transition between paper drawings and OpenMusic, a flexible music composition tool. Musink's built-in recognizers handle common needs, such as scoping and annotation. Users can also define new gestures and associate them with their own or predefined software functions. Musink supports semi-structured, delayed interpretation and serves as a customizable gesture browser, giving composers significant freedom to create their own, individualized composition languages and to experiment with music, on-paper and on-line.

Tabard, Aurlien, Mackay, Wendy E., Roussel, Nicolas and Letondal, Catherine (2007): PageLinker: integrating contextual bookmarks within a browser. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 337-346.

PageLinker is a browser extension that allows to contextualise navigation by linking web pages together and to navigate through a network of related web pages without prior planning. The design is based on extensive interviews with biologists, which highlighted their difficulties finding previously visited web pages. They found current browser tools inadequate, resulting in poorly organised bookmarks and rarely used history lists. In a four-week controlled field experiment, PageLinker significantly reduced time, page loads and mouse clicks. By presenting links in context, PageLinker facilitates web page revisitation, is less prone to bookmark overload and is highly robust to change.

Letondal, Catherine (2006): Participatory programming: Developing programmable bioinformatics tools for end-users. In: Lieberman, Henry, Paterno, Fabio and Wulf, Volker (eds.). "End User Development (Human-Computer Interaction Series)". Springerpp. 207-242

We describe participatory programming as a process that spans design, programming, use and tailoring of software. This process, that includes end-users at each stage, integrates participatory design and programmability. Programmability, as a property that relies on a reflective architecture, aims to let the end-users evolve the tools themselves according to their current, specific needs, and to let them control better the way results are computed. We present an environment that results from this approach, called biok, developed for researchers in biology, which is both domain-oriented and open to full programming.

Letondal, Catherine and Mackay, Wendy E. (2004): Participatory programming and the scope of mutual responsibility: balancing scientific, design and software commitment. In: Clement, Andrew and Besselaar, Peter Van den (eds.) PDC 2004 - Proceedings of the Eighth Conference on Participatory Design July 27-31, 2004, Toronto, Ontario, Canada. pp. 31-41.

Over the past seven years, we have been conducting a variety of participatory design activities with research biologists, programmers, and bioinformaticians at the Institut Pasteur in Paris. We first describe the history of these activities and how they have created the beginnings of a participatory design culture. We introduce participatory programming, which integrates participatory design and end-user programming, and examine how it acts as a medium for forging scientific ideas. Finally, we reflect on three poles of activity: the computational medium, scientific hypotheses and participatory design.

Mackay, Wendy E., Pothier, Guillaume, Letondal, Catherine, Boegh, Kaare and Sorensen, Hans Erik (2002): The missing link: augmenting biology laboratory notebooks. In: Beaudouin-Lafon, Michel (ed.) Proceedings of the 15th annual ACM symposium on User interface software and technology October 27-30, 2002, Paris, France. pp. 41-50.

Using a participatory design process, we created three prototype augmented laboratory notebooks that provide the missing link between paper, physical artifacts and on-line data. The final a-book combines a graphics tablet and a PDA. The tablet captures writing on the paper notebook and the PDA acts as an "interaction lens" or window between physical and electronic documents. Our approach is document-centered, with a software architecture based on layers of physical and electronic information.
