* My main interest area is automation in complex socio-technical system. While the declared purposes for introducing automation are to increase safety and productivity, understanding how practitioners achieve their objectives in the current environment is fundamental. Consequences linked to introducing automation have to be anticipated if "automation surprises" have to be prevented. It is only through modelling how people share knowledge and other resources that we can develop hypothesis about the impact of automation and thus what requirements the system should meet. A long-term research interest is activity modelling through direct observation of practitioners in "natural" and simulated environments, interviewing practitioners through the use of scenarios, and during routine operations. I have been particularly concerned with modelling decision making and diagnostic processes (Amaldi, 1993; .Amaldi, Barale, & Di Rienzo, 2000) * A related area is validation of advanced automated tools. What type of evidence do we need to support the finding that the tool is validated? Checking that requirements are met is definitely an important step. This, however raises the issue of how requirements are gathered and later validated. Requirement gathering implies not only drawing up a list of desiderata but also generating an initial activity model of the target population (Amaldi, Wilson, 2002). Without such an activity modelling, requirements cannot be validated as it would be impossible to justify designers' choice and individual variability, among other things. Complex tools cannot be validated just by looking for metrics to measure "productivity" and "safety". A more systemic approach should be considered where the tool is assessed in the context of the activities concerned by the tool (Amaldi, & Cellier, 1998). * My main application domain is automation issues in Civil Aviation. For over ten years I have collaborated with National Research and Development Centers for designing and testing new technology for air traffic controllers and commercial airline pilots. Thus I have worked for the Federal Aviation Administration in the USA, for the Centre d'Etude de la Navigation Aerienne in France, for the Italian National Agency for Air Traffic Control (ENAV). Actually I am involved in a project, called Fast Prototype, concerned with the development of a radar control station for airport tower air traffic controllers. We are implementing ethnographic approach to the study of how expert practitioners share available resources to make the environment productive and safe, in spite of the several opportunities to generate "system breakdowns".

Joyekurun, Ronish, Wong, William and Amaldi, Paola (2008): Responding to Uncertainty on Approach in Hazardous Situations. In: ICRAT 08 International Conference on Research in Air Transportation 2008 June 1-4, 2008, Fairfax, Virginia, USA. p. 7.

The management of uncertainty is a recurring theme in Air Traffic Management and in understanding the way operators accomplish their objectives in a complex, dynamic environment. The current study reports on the verbal communication processes of crews and controllers during the approach flight phase and faced by uncertain situations. A conversation analysis of six (6) accident transcripts was conducted, with dynamic environmental interactions as a complexity factor. The results are presented in the forms of correlations among factor pairs. Results indicate a large variation (5.46%-32.09%) of the detection of uncertainty across accidents. Air Traffic Control and Ground Services (ATC/Ground) rarely initiated problem-solving exchanges (7%) in uncertain situations, as compared to crews (93%). Crews initiated 80.6% of problem-solving exchanges based on the direct perception of environmental cues while ATC/Ground initiated 19.4% of exchanges based only on indirect cues. Finally, our results indicate that ATC/Ground account for 68.8% of overlapping and 88.9% of compounded verbal exchanges. We conclude that the response to uncertain situations arising from hazardous conditions seems to correlate with a management by crews on approach. The effective transfer of uncertainty cues between crews and controllers does not appear to correlate with collaborative and communicative practices.

How do we design to improve the safety of approach operations in adverse atmospheric conditions? More importantly, what are the problematic issues in the work environment which our design hypotheses need to address? This paper discusses the specificities of collaborative work on approach. Previous results are presented in the form of collaborative themes of work which allow air-ground teams to be treated as a functional unit of analysis on approach. Last, we discuss observations with air-ground communications encountered in an ongoing study and raise a number of implications for improving the collaborative work on approach.

During adverse atmospheric conditions, many crews and controllers are seen to attempt hazardous approaches, which sometimes lead to accidents; this occurs despite the availability of atmospheric information during relatively low workload situations.

In this paper we briefly report on our investigations into the development of representation design techniques to take advantage of capabilities that a novel Multi-Layered Display (MLD) technology affords for improving information uptake in information intensive environments. The MLD comprises two LCD screens separated by a 14 mm thick transparent perspex layer. Data presented on the rear screen is viewable through the front LCD. By combining transparency, colour, form of the data, and motion, we can create physically distinct layers of information which affords new ways of presenting information, such as information layering, focus + context, visual linking and information foraging support. Because of the visual effects caused by overlaying information in the physical layers, some of the old rules of display design such as optimal colour combinations, are no longer applicable within this context. New techniques for visualisation and interaction are needed, not just to make such a display readable, but also to take advantage of the new display capabilities. While we are still some way from prescribing techniques for designing information in layers across physically overlapping displays, we will also discuss five early lessons learned from the process of developing such design techniques.

Software design is the act of determining the user's experience with a piece of software. It has nothing to do with how the code works inside, or how big or small the code is. The designer's task is to specify completely and unambiguously the user's whole experience.

-- David Liddle, From Bringing Design to Software, edited by Terry Winograd, 1996
