“There is growing concern about the role of technological exclusion on deepening economic, political and social inequalities. Many people do not have PC-based Internet access either through geography, lack of money or other disadvantages. At the same time there is continued growth in the use of digital interactive television (DiTV) in the home, suggesting the potential for an alternative channel of Internet access. However, the case for DiTV is not proven, with some evidence of lack of awareness and interest among potential users. The purpose of this paper is to explore the role of DiTV as an alternative platform for conducting e-commerce among people who might otherwise be at risk of e-exclusion. The paper is positioned against literature on adoption of DiTV and briefly presents the results of a qualitative study examining consumer beliefs and feelings about shopping via DiTV. Eight key issues arising from the study are used as the focus for a questionnaire distributed among residents in an area of economic deprivation. The main outcomes are a deeper understanding of the pros and cons of DiTV for e-commerce and recommendations for developers wishing to promote e-inclusion.”

“Historical analysis is a new method for evaluating requirement capture methodologies. The method consists of three components. First there is the application of a specification analysis technique. This technique is applied to the requirement specification of an existing software product, and is used to predict performance of a product built to that specification. The second component involves surveying actual use of the product. The third component allows a comparison to be made between the predicted and actual product performance. A valid requirements capture methodology should successfully anticipate a significant number of the actual performance problems. The method was used to evaluate the user skills and task match (USTM) methodology. Two case studies were undertaken. The results from the case-work confirm the value of USTM, and demonstrate the power of the historical analysis method as an evaluation tool.”

Proceedings of the Fourth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers IV August 5-9, 1988, University of Manchester, UK. pp. 111-122.
“Poor specification of user requirements is a major reason why computer systems fail or dysfunction. One way of addressing this problem is to validate User Requirements Specifications before proceeding with system development. To date, it has only been possible to validate specifications against checklists of what they should contain. This type of validation indicates gaps but does not check the reliability of a specification; nor does it explain the implications of specification deficiencies for performance of the finished product. This paper identifies obstacles to the development of validation techniques that do check reliability and do explain the implications of specification deficiencies. An approach to overcoming these obstacles is discussed, particularly a method for ensuring that a specification is verified with the right set of users, and a method of manipulating and analysing the information in a specification to predict dysfunction. This approach has been used to develop the Specified User Requirements Validation and Explication (SURVE) technique.”

Fowler, C. J. H., Macaulay, L. A. and Siripoksup, S. (1987): An Evaluation of the Effectiveness of the Adaptive Interface Module (AIM) in Matching Dialogues to Users. In: Diaper, Dan and Winder, Russel (eds.) Proceedings of the Third Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers III August 7-11, 1987, University of Exeter, UK. pp. 345-359.
“The present study represents an evaluation of an Adaptive Interfaces Module, which attempts to offer users an appropriate type of dialogue to meet their particular requirements and preferences. The investigation focuses on two main user characteristics: task/system expertise and cognitive style. Cognitive style was assessed on the field-dependence-independence dimension, and the level of task/system expertise was determined by the amount of exposure to the system. A number of different types of dialogue were generated, which varied in terms of their overall form, structure and content. The analysis of the results suggests that cognitive style and task/system expertise are important variables in determining an effective user-dialogue match. Novice users seem to prefer dialogues which are system-guided and demand a limited and specified sequence of inputs from the user. In contrast, users with increased experience appear to be more able to cope with a wider range of dialogues. The cognitive style findings are discussed in terms of different initial learning strategies adopted by users in the formulation of their task/system models. Finally some of the limitations of the experiment are discussed and suggestions for future research are made.”

Proceedings of the Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers I August 17-20, 1985, University of East Anglia. pp. 186-198.
“This paper presents and discusses findings from an explorative study which examined the relationship between cognitive style and dialogue style as reflected in various measures of performance. The cognitive style dimension used in this investigation was field-dependence/independence (Witkin and Goodenough, 1981), as measured by the GEFT, the main dialogue style variable was the kind of command structure (linear and substructure), and the main performance variables were time taken to complete a task ('thinking' and 'doing'), the number of 'Help' requests, the number of corrected/uncorrected errors, and the kind of error made (usage or typographical). These variables were examined over two different learning blocks using 48 subjects. The results were analysed by the use of correlational techniques. The results suggested that field-dependent persons tend to prefer a substructured command language and that field-independent individuals show a general preference for linear command structure. These results were interpreted in terms of differences in mode of information processing arising from a greater or lesser reliance on external referents. The authors conclude that cognitive style is an important concept in relation to human-computer interaction, and may be of considerable use in the area of interface design.”

Macaulay, L. A., Fowler, C. J. H. and Porteus, R. (1985): What Do Clerical Workers Think About Computers?. In: Johnson, Peter and Cook, Stephen (eds.) Proceedings of the Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers I August 17-20, 1985, University of East Anglia. pp. 290-298.
“The attitudes towards computers of a sample (N=48) of clerical workers were measured by means of a questionnaire. The individual items used were taken from a questionnaire originally designed and used by Zoltan and Chapanis (1982). The clerical workers' responses were then compared with those of the four professional groups sampled in Zoltan and Chapanis' study -- i.e. accountants, lawyers, pharmacists and physicians. The results suggest that with respect to computers the attitudes of clerical workers closely resemble those of pharmacists, and tend to be more positive than those of lawyers and physicians. The findings are explained in terms of the similarities and differences between the various occupations and the degree to which computers are able to assist in the sort of tasks which characterise each occupation.”

“The nature of the user interface should be adaptive to accommodate variations in user skill levels and cognitive style. The paper includes a brief review of current research on dialogue design, and describes aspects of an experiment carried out into the use of functional simplicity in dialogue design. The experimental session is described briefly and results based on keystroke timings are reported upon. Further findings from the experiments are reported upon elsewhere, including [16].”
