Kodagoda, Neesha and Wong, B. L. William (2008): Effects of Low & High Literacy on User Performance in Information Search and Retrieval. In: Proceedings of the HCI08 Conference on People and Computers XXII 2008. pp. 173-181. Available online

“This study was part of research into understanding the nature of how low literacy users search for and retrieve information, and to therefore develop systems and user interface designs that would empower low literacy users to find information they need in the rapidly evolving e-government and e-social services environment. We compared information search and retrieval performance between high and low literacy users of a Citizens Advice Bureau information kiosk system in the UK. The kiosk provided self-help information in a number of social services areas. Six high literacy and six low literacy users were presented with information search tasks classified as having low, medium and high complexity. Key results indicate that (i) low literacy users take eight times more time than high literacy users to complete an information search task, and yet were significantly less accurate, (ii) low literacy users on average spent one-third more time on a web page than high literacy users, but did not seem to be informed by it, (iii) low literacy users employed a much less focused information search strategy than high literacy users visiting eight times more web pages in total, (iv) low literacy users back-tracked 13 times more frequently than high literacy users, and are four times more likely to re-visit web pages, and (v) low literacy users are 13 times more likely to be lost than high literacy users.”

Wong, B. L. William, Joyekurun, Ronish, Mansour, Hoda, Amaldi, Paola, Nees, Anna and Villanueva, Rochelle (2005): Depth, layering and transparency: developing design techniques. In: Proceedings of OZCHI05, the CHISIG Annual Conference on Human-Computer Interaction 2005. pp. 1-10. Available online

“In this paper we briefly report on our investigations into the development of representation design techniques to take advantage of capabilities that a novel Multi-Layered Display (MLD) technology affords for improving information uptake in information intensive environments. The MLD comprises two LCD screens separated by a 14 mm thick transparent perspex layer. Data presented on the rear screen is viewable through the front LCD. By combining transparency, colour, form of the data, and motion, we can create physically distinct layers of information which affords new ways of presenting information, such as information layering, focus + context, visual linking and information foraging support. Because of the visual effects caused by overlaying information in the physical layers, some of the old rules of display design such as optimal colour combinations, are no longer applicable within this context. New techniques for visualisation and interaction are needed, not just to make such a display readable, but also to take advantage of the new display capabilities. While we are still some way from prescribing techniques for designing information in layers across physically overlapping displays, we will also discuss five early lessons learned from the process of developing such design techniques.”

Blandford, Ann and Wong, B. L. William (2004): Situation awareness in emergency medical dispatch. In International Journal of Human-Computer Studies, 61 (4) pp. 421-452

“Situation awareness, and how systems can be designed to support it appropriately, have been a focus of study in dynamic, safety critical contexts such as aviation. The work reported here extends the study of situation awareness into the domain of emergency medical dispatch (EMD). The study was conducted in one of the largest ambulance services in the world. In this study, we encountered development and exploitation of situation awareness, particularly among the more senior EMD operators called allocators. In this paper we describe the notion of a 'mental picture' as an outcome of situation awareness, how an awareness of the situation is developed and maintained, the cues allocators attend to, and the difficulties they face in doing so. One of the key characteristics of ambulance control is that relatively routine behaviour is periodically interspersed with incidents that demand much higher levels of attention, but that the routine work must still be completed; operators exhibit contrasting levels of situation awareness for the different kinds of incidents. Our findings on situation awareness are related to those of others, particularly Endsley and Wickens. The observations and interviews enable us to propose high-level requirements for systems to support appropriate situation awareness, to enable EMD staff to complete their work effectively.”
