Veer, Gerrit C. van der, Ebert, Achim and Scheler, Inga (2011): Non-formal modelling for interaction design. In: Proceedings of the 2011 Annual European Conference on Cognitive Ergonomics 2011. pp. 215-216.

“Motivation -- If modelling is included in the requirements analysis phase of a systematic interaction design method, it mostly focuses on some kind of formalism, e.g., task modelling and requirements specification. However, when designing in collaboration with non-expert, stakeholders this will not work. Approach -- This workshop will allow exchange of ideas, experiences, techniques and tools for collaboration with stakeholders of interaction design early in the design process, in order to aim at a more creative as well as more user-centred requirement development. Limitations/Implications -- Our finding will in no way guarantee "the best design solution", but they show a type of creative collaboration between stakeholders and designers in a very early design phase, which allows considering and exploring new solutions before these need to be prototyped or implemented. Originality/Value -- The techniques we intend to discuss are in no way new, however their application early in design in this open ended approach is not well documented and, hence, awareness and comparing notes on successes and failure experiences will allow us to learn from each other and help us develop a general understanding among interaction designers. Take away message -- Non-formal modelling tools and techniques for early collaboration with stakeholders are relatively cheap and, at the other hand, uniquely stimulating techniques for identifying both the boundaries and the opportunities of the design space for interactive systems.”

Ebert, Achim, Deller, Matthias, Thelen, Sebastian and Scheler, Inga (2011): iGreen: non-formal modelling in practice. In: Proceedings of the 2011 Annual European Conference on Cognitive Ergonomics 2011. pp. 283-284.

“Motivation -- In the following we describe the development of new visualization and interaction metaphors in the context of iGreen. iGreen is a project dealing with knowledge management in the agricultural industry. We give two example scenarios in which formal modelling cannot be applied easily. Research approach -- The number of actors participating in iGreen is high and encompasses different levels of background knowledge, project expectations, and technical affinities. Over the course of time objective targets gradually changed due to an increased understanding of processes within the project and new unforeseen technical opportunities that turned up in the area of mobile computing. The methods developed had to be accessible for a wide variety of potential users and offer opportunities for interactive data exploration on various hardware platforms. Findings/Design -- The project dynamic made conventional software development strategies hard to apply. The demand for more flexible methods to design visualization techniques and interaction metaphors portable and scalable to different sized hardware platforms increased during the project. Research limitations/Implications -- The target group of users for techniques developed in iGreen is highly related to practice. In order to overcome adaption resistances and replace traditional, mostly manual, workflows, the methods had to be highly intuitive, reliable, and offer steep learning curves. Take away message -- Two application areas in the field of agricultural industry are discussed for which visualization and interaction techniques have been developed. Both examples represent different ends of a wide spectrum of potential target platforms that had to be served.”
