Cauchi, Abigail, Gimblett, Andy, Thimbleby, Harold, Curzon, Paul and Masci, Paolo (2012): Safer "5-key" number entry user interfaces using differential formal analysis. In: Proceedings of the HCI12 Conference on People and Computers XXVI 2012. pp. 29-38.

“Differential formal analysis is a new user interface analytic evaluation method based on stochastic user simulation. The method is particularly valuable for evaluating safety critical user interfaces, which often have subtle programming issues. The approach starts with the identification of operational design features that define the design space to be explored. Two or more analysts are required to analyse all combinations of design features by simulating keystroke sequences containing keying slip errors. Each simulation produces numerical values that rank the design combinations on the basis of their sensitivity to keying slip errors. A systematic discussion of the simulation results is performed for assessing the causes of any discrepancy, either in numerical values or rankings. The process is iterated until outcomes are agreed upon. In short, the approach combines rigorous simulation of user slip errors with diversity in modelling and analysis methods. Although the method can be applied to other types of user interface, it is demonstrated through a case study of 5-key number entry systems, which are a common safety critical user interface style found in many medical infusion pumps and elsewhere. The results uncover critical design issues, and are an important contribution of this paper since the results provide device manufacturers guidelines to update their device firmware to make their devices safer.”

Furniss, Dominic, Blandford, Ann and Curzon, Paul (2011): Confessions from a grounded theory PhD: experiences and lessons learnt. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 113-122.

“Grounded Theory (GT) is used within HCI research, but nuances and more modern interpretations of the method are rarely discussed. This paper has two intentions: to offer guidance on practical issues when applying GT, and to clarify the space of methodological possibilities. We describe an extended GT study on understanding why practitioners choose particular usability evaluation methods. We describe five stages in this study to highlight our experiences and choices made. We draw out seven practical and methodological considerations in applying GT in a CHI context. This challenges the more traditional inductive and objective positions on GT use; it sensitizes novices of GT to these issues; and through the extended case study it provides substance for debate on issues that affect those that use qualitative methods more broadly.”

Curzon, Paul, Wilson, Judy and Whitney, Gill (2005): Successful strategies of older people for finding information. In Interacting with Computers, 17 (6) pp. 660-671.

“Older people have successful search strategies for finding practical information in everyday situations but, increasingly, traditional information sources are being supplemented or replaced by web based ones. However, there are wider issues than just making information available if people are to replace existing strategies by new web based ones. In this paper we use three studies on the information usage of older people to explore the issues surrounding why they favour specific search strategy and technology combinations. The studies each investigate different aspects of information search in a natural setting and concern tasks relevant to older people as their lives change: finding e-government information and planning travel. Results suggest that a variety of measures are important in choice of strategy. Furthermore, interface mechanisms are needed that complement existing strategies, reinforce the existence and crossing of boundaries, and support interactive use of landmarks.”

Blandford, Ann, Butterworth, Richard and Curzon, Paul (2004): Models of interactive systems: a case study on programmable user modelling. In International Journal of Human-Computer Studies, 60 (2) pp. 149-200.

“Models of interactive systems can be used to answer focused questions about those systems. Making the appropriate choice of modelling technique depends on what questions are being asked. We present two styles of interactive system model and associated verification method. We show how they contrast in terms of tractability, inspectability of assumptions, level of abstraction and reusability of model fragments. These trade-offs are discussed. We discuss how they can be used as part of an integrated formal approach to the analysis of interactive systems where the different formal techniques focus on specific problems raised by empirical investigations. Explanations resulting from the formal analyses can be validated with respect to the empirical data. The first modelling style, which we term 'operational', is derived directly from principles of rationality that constrain which user behaviours are modelled. Modelling involves laying out user knowledge of the system and task, and their goals, then applying the principles to reason about the space of rational behaviours. This style supports reasoning about user knowledge and the consequences of particular knowledge in terms of likely behaviours. It is well suited to reasoning about interactions where user knowledge is a key to successful interaction. Such models can readily be implemented as computer programs; one such implementation is presented here. Models of the second style, 'abstract', are derived from the operational models and thus retain important aspects of rationality. As a result of the simplification, mathematical proof about selected properties of the interactive system, such as safety properties, can be tractably applied to these models. This style is well suited to cases where the user adopts particular strategies that can be represented succinctly within the model. We demonstrate the application of the two styles for understanding a reported phenomenon, using a case study on electronic diaries.”

Curzon, Paul, Keith, Suzette, Wilson, Judy and Whitney, Gill (2004): Strategies for Finding Government Information by Older People. In: Proceedings of the 8th ERCIM Workshop on User Interfaces for All 2004. p. 34.

“Governments increasingly expect web technology to become their major way of exchanging information with citizens, replacing existing methods. They also give accessibility a high priority. Older people are a major user of government services. We describe a pilot study comparing attitudes of older people to e-government with other ways of obtaining information. We examine what individuals consider important in an information search strategy, and the relative effectiveness of each for achieving an individuals personal aims. We do this in the light of research on the effects of aging on cognitive skills.”
