The context of this research is cooperative engineering, namely the adapted IT environmentsupport that is required for projects involving temporarily teams of heterogeneous actors fromdifferent firms cooperating and collaborating together for achieving a set of activities. This kindof environment is needed for example in the construction sector for problem supportingactivities on a construction site, and requires some flexibility and efficiency regarding themethodology and the supporting tools. These objectives lead us to the Dest2co project (FNRCore08), in which we aim at determining a model-driven service design methodology suitablefor addressing the requirements of IT services in highly collaborative environments. In thisproject proposal we propose to augment this methodology towards the generation of userinterfaces, through an iterative process made from 3 successive major steps.The first step is related to the modelling of the business domain, i.e. any relation to the tasks ofthe operator and the context in which these tasks occur. Thus, four main elements areconsidered: the project, the organization, the collective work and the user profile.The second step consists in automatically generating an adaptive Human-Computer Interfacebased on the modelling of the various issues identified during the step 1. This step is enhancedthrough ergonomic criteria constraining the interface generation, and involves the modelling ofergonomic heuristics that can be referenced in the literature.Finally, the third stage is based on a feedback process that enriches the understanding ofmodels developed in step 1. These feedbacks will allow to collect information on the use of theinterface created previously. They provide valuable information useful in designing futureinterfaces, adding to their plasticity.Several types of results are planned for each stage of the methodological approach that wepropose:• the definition and development of models for automatic generation of user interface. Thisresult enriches the knowledge about “model-driven engineering of user interfaces” thematic;• a proposal of modelling heuristics to generate ergonomic interfaces. This is particularlyinnovative because many studies show the difficulty of systematizing the ergonomic designof interfaces;• a comprehensive listing of advantages and weaknesses of automated interface creationrelative to ergonomics / usability and as compared to well approved empirical iterativeworkflows;• a generic framework for the automatic generation of interface, including a step of collectinginformation needed to adapt gradual interfaces. The aim is to provide a basis for statisticalanalysis related to a number of performance indicators to be identified.The proposed GENIUS methodology will be validated through an experimental protocol basedon a case study. Generation and feedback mechanisms will be experimented and compared onexisting HCIs developed for the construction domain.
