Colbert, Martin and Boodoo, Angela (2011): Does 'Letting Go of the Words' Increase Engagement: a traffic study. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 655-667.
This case study explores the effects of written online content on user engagement, and describes the challenges of conducting experiments on live web sites. It compares two versions of a website about bicycle maintenance and repair. One version complied with the guidelines for written online content in "Letting Go of the Words" (Redish, 2007), the other version did not. Web metrics suggested visitors were more engaged with the guideline-compliant version in some respects. Visitors appeared to spend longer on the compliant site, and were more likely to revisit the compliant site, but they were not tempted to explore it further. Conducting this traffic study presented several challenges -- notably, how to profile visitors, and how to demonstrate statistical significance.

Colbert, Martin and Livingstone, David (2006): Important context changes for talking and text messaging during homeward commutes. In Behaviour and Information Technology, 25 (5) pp. 433-441.
This paper models the suitability of homeward commutes as a context for talking on a mobile telephone and text messaging. Analysis of these models identifies when and where large changes in suitability frequently arise. To bring commuters the greatest benefits, these are the changes upon which future applications of context-sensitivity and awareness need to focus.

Proceedings of the International ACM SIGGROUP Conference on Supporting Group Work 2001 September 30 - October 3, 2001, Boulder, Colorado, USA. pp. 15-23.
This paper presents a diary study of rendezvousing as performed by university students. The study suggests that endezvousing frequently does not occur exactly as planned, but this is not necessarily problematic. It also reveals that 'problem' rendezvous were attributed more frequently to modes of travel, over-running of previous activities and lack of information about other rendezvousers, than to lack of information about travel, or local geography. These, and other, findings have implications for the design of position-aware computing and communications for the general public.

Colbert, Martin (1997): Style Guides and Their Application: The Case of Microsoft 'Windows' and a Remote Tutoring Environment. In Behaviour and Information Technology, 16 (1) pp. 25-42.
The application of Graphical User Interface styles is supported by 'style guides' -- books which authoritatively specify a basic set of application controls (interface objects) and user input methods, and which advise when and how to use these controls and input methods. Style guides are typically presented as resources that encourage consistency and re-use. This paper reports a recent project which applied the Microsoft 'Windows' style as a de facto standard, rather than a resource. The style was applied in this manner, to offer potential customers a guarantee of usability (of a kind). The project was a success, in that the Windows re-design of a remote tutoring environment out-performed the previous, push button design in key respects in a usability trial. However, with the benefit of hindsight, the Windows re-design was also unnecessarily complex, because the project's view of style compliance was somewhat misleading. If styles are to be used as de facto standards, then it is suggested that projects are provided with explicit concepts of style compliance, compliance rules and compliance assessment procedures.

Colbert, Martin, Peltason, Christof, Fricke, Rolf and Sanderson, Mariana (1997): The Application of Process Models of Information Seeking During Conceptual Design: The Case of an Intranet Resource for the Re-Use of Multimedia Training Material in the Motor Industry. In: Proceedings of DIS97: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 1997. pp. 73-81.
Process models of information seeking are widely held in the Human-Computer Interaction research community. This paper reports a project which applied such models to the design of an intranet resource for the re-use of multimedia training material in the motor industry. The models were found to help identify inherent limitations of an initial prototype, and to support the import of design ideas from other Web sites. However, the process models did not help to identify the information objects that information seekers may need to access and manipulate (documents, tables of contents, item summaries, indexes, lists of linked items etc). To better support design, it is suggested that process models of information seeking be expanded to include such objects. Also, designers may wish to regard process models as usable and useful, but incomplete.

Colbert, Martin and Long, John (1996): Towards the Development of Classes of Interaction: Initial Illustration with Reference to Off-Load Planning. In Behaviour and Information Technology, 15 (3) pp. 149-181.
In recent years, a number of difficulties in designing interactions between military personnel and their command and control systems have been identified. These difficulties have been attributed to a lack of carry forward between procurement projects. This paper suggests that lack of carry forward is an integral part of current 'case by case' approaches to HCI. Consequently, a fundamentally different approach to HCI is required. The approach suggested here is a class approach. A class approach to HCI makes class <--> instance relationships between knowledge representations explicit by organising knowledge representations into class hierarchies. Given such hierarchies, procurement projects may consider the relevance of existing knowledge by attempting to locate the problem at hand within the hierarchy. Thus, a class approach to HCI may encourage carry forward by providing: (a) the opportunity to develop multiple instances of classes of interaction by specialising and instantiating class knowledge representations for the instances at hand; (b) the opportunity to apply research knowledge at different levels of development -- to the development of the class and the instance (not just the case); and (c) an additional means of reasoning about the completeness/selectivity of instance knowledge representations -- with respect to relevant, super-ordinate representations. This paper presents an initial illustration of a class approach to HCI. It identifies some key characteristics of a class approach to HCI, and then presents research and development work which exhibits these characteristics. Such an illustration is required, because current understanding about the nature of HCI concerns, and the relationships between HCI knowledge, practices and problems is such that one may not assume that all desirable approaches to HCI are necessarily realisable. Successful initial illustration provides an additional, encouraging precedent for full development of the approach.

Whitefield, Andy, Wight, Julie, Life, Andrew and Colbert, Martin (1991): Assessing the Programming Language PML as a Task Analysis Method and Product. In: Diaper, Dan and Hammond, Nick (eds.) Proceedings of the Sixth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers VI August 20-23, 1991, Heriot-Watt University, Edinburgh, UK. pp. 403-417.
This paper reports a feasibility study to investigate the possible use of the programming language PML (Process Modelling Language) for task analysis. In so doing, it proposes a number of criteria for assessing task analyses. The study used PML to analyse and describe the task of producing a multi-author research proposal. To assess the suitability of PML for this purpose, a number of criteria were identified, concerning the effectiveness of: the task analysis product; the task analysis method notational support; and the task analysis method procedural support. The assessment of PML suggests that it may well be suitable for task analysis, generating a task analysis product particularly appropriate for software engineers developing multi-role systems, and offering a clear notation for a task analysis method. Its principal weakness is the lack of procedural support it provides as a task analysis method.
