Teoh, Cameron, Regenbrecht, Holger and O'Hare, David (2011): The transmission of self: body language availability and gender in videoconferencing. In: Proceedings of the 2011 Australian Computer-Human Interaction Conference 2011. pp. 273-280.

“Videoconferencing technology is increasingly used for work and personal use. While a lot of research has been done on the perceptual qualities of videoconferencing systems, little research has been done on self-transmission or the ways in which individuals manage and control the impressions received by the communication partner. In an experimental study with 134 participants, we investigated the influence of the availability of body language and both partners' gender on the ability to transmit oneself in videoconferencing. We found that participant gender and partner gender both had significant effects on perceptions of dominance/persuasion and impression management. We discuss these results in relation to the transmission of self in remote communication and their implications for future design and research.”

Wong, William B. L., O'Hare, David and Sallis, Philip J. (1998): The Effect of Layout on Dispatch Planning and Decision Making. In: Johnson, Hilary, Nigay, Laurence and Roast, C. R. (eds.) Proceedings of the Thirteenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XIII August 1-4, 1998, Sheffield, UK. pp. 221-238.

“This paper reports on an experiment conducted to determine whether the manner in which information is portrayed affects ambulance planning and dispatch decision making performance. Based the outcomes of a series of cognitive task analysis, deficiencies in an actual ambulance status display used for dispatch management was identified. The display was then re-designed by applying cognitive engineering principles to achieve task-to-display compatibility. The new display was then evaluated and it was found to improve dispatch decision making performance by 40%.”

Wong, William B. L., Sallis, Philip J. and O'Hare, David (1997): Eliciting Information Portrayal Requirements: Experiences with the Critical Decision Method. In: Thimbleby, Harold, O'Conaill, Brid and Thomas, Peter J. (eds.) Proceedings of the Twelfth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XII August, 1997, Bristol, England, UK. pp. 397-415.

“This study is part of research that is investigating the notion that human performance in dynamic and intentional decision making environments, such as ambulance dispatch management, can be improved if information is portrayed in a manner that supports the decision strategies invoked to achieve the goal states of the process being controlled. Hence, in designing interfaces to support real-time dispatch management decisions, it is suggested that it would be necessary to first discover the goal states and the decision strategies invoked during the process, and then portray the required information in a manner that supports such a user group's decision making goals and strategies. The purpose of this paper is to report on the experiences gleaned from the use of a cognitive task analysis technique called Critical Decision Method as an elicitation technique for determining information portrayal requirements. This paper firstly describes how the technique was used in a study to identify the goal states and decision strategies invoked during the dispatch of ambulances at the Sydney Ambulance Coordination Centre. The paper then describes how the interview data was analysed within and between cases in order to reveal the goal states of the ambulance dispatchers. A brief description of the resulting goal states follows, although a more detailed description of the goals states and their resulting display concepts has been reported elsewhere (Wong et al., 1996b). Finally, the paper concludes with a set of observations and lessons learnt from the use of the Critical Decision Method for developing display design concepts in dynamic intentional environments.”

Wong, William, Sallis, Philip and O'Hare, David (1995): Information Portrayal for Decision Support in Dynamic Intentional Process Environments. In: Proceedings of OZCHI95, the CHISIG Annual Conference on Human-Computer Interaction 1995. pp. 43-48.

“This paper is part of a study to determine the information portrayal requirements of dynamic process environments, and in particular reports on preliminary findings of a cognitive task analysis (CTA) conducted at an ambulance dispatch control center. The centre uses the Computer-Assisted Dispatch System to manage its ambulance operations. The intense and dynamic nature of the decision making environment is first described, and the decision process modelled in an attempt to identify decision strategies used by the dispatch officers. Some information portrayal requirements stemming from one of the decision processes are then discussed, and these requirements are then translated into a proposed display solution.”
