In domains where users are exposed to large variations in visuo-spatial features among designs, they often spend excess time searching for common elements (features) on an interface. This article contributes individualised predictive models of visual search, and a computational approach to restructure graphical layouts for an individual user such that features on a new, unvisited interface can be found quicker. It explores four technical principles inspired by the human visual system (HVS) to predict expected positions of features and create individualised layout templates: (I) the interface with highest frequency is chosen as the template; (II) the interface with highest predicted recall probability (serial position curve) is chosen as the template; (III) the most probable locations for features across interfaces are chosen (visual statistical learning) to generate the template; (IV) based on a generative cognitive model, the most likely visual search locations for features are chosen (visual sampling modelling) to generate the template. Given a history of previously seen interfaces, we restructure the spatial layout of a new (unseen) interface with the goal of making its features more easily findable. The four HVS principles are implemented in Familiariser, a web browser that automatically restructures webpage layouts based on the visual history of the user. Evaluation of Familiariser (using visual statistical learning) with users provides first evidence that our approach reduces visual search time by over 10%, and number of eye-gaze fixations by over 20%, during web browsing tasks. ; The project has partially received funding from the Academy of Finland project COMPUTED and the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement 637991).

Design artefacts are vital to communicate design outcomes, both in remote and co-located settings. However, it is unclear how artefacts are used to mediate interactions between designers and stakeholders of the design process. The purpose of this paper is exploring how professional design teams use artefacts to guide and capture discussions involving multidisciplinary stakeholders while they work in a co-located setting. An earlier draft of this paper was paper published in the Proceedings of the European Conference on Cognitive Ergonomics (ECCE 2017). This work adds substantial clarification of the methodology followed, further details and photographs of the case studies, and an extended discussion about our findings and their relevance for designing interactive systems. We report the observations of six design meetings in three different projects, involving professional design teams that follow a user-centered design approach. Meetings with stakeholders are instrumental for design projects. However, design teams face the challenge of synthesizing large amounts of information, often in a limited time, and with minimal common ground between meeting attendees. We found that all the observed design meetings had a similar structure consisting of a series of particular phases, in which design activities were organized around artefacts. These artefacts were used as input to disseminate and gather feedback of previous design outcomes, or as output to collect and process a variety of perspectives. We discuss the challenges faced by design teams during design meetings, and propose three design directions for interactive systems to coordinate design meetings revolving around artefacts ; The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP7/2007-2013) / ERC grant agreement n° 610725 (COnCEPT project)
