A summative usability evaluation of a desktop virtual reality (VR) system was developed and a preliminary study then conducted. The purpose of the study was twofold. Firstly, to test whether the traditional evaluation technique, co-operative evaluation, is effective in the evaluation of desktop VR systems. Co-operative evaluation is a variation on a ‘think-aloud’ verbal protocol, whereby, in ad...

Scripts are sites of religious, cultural and political power. Although scripts are often viewed solely as technical devices in the service of meaning, the particular histories of scripts’ coming into being, their uses and sometimes disappearance can tell us much about shifting religious agendas, memory and forgetting, and attachment to community and place. In my talk I explore the history of wr...

In recent years, we have investigated algorithmic methods for automatically discovering and optimizing sequential treatments for chronic and life-threatening diseases. In this talk I will discuss two aspects of this work, first the problem of efficiently collecting data to learn good sequential treatment strategies, and second the problem of using data collected in multi-stage sequential trials...

g in usability research onal usability testing. There are various methodologies available when conducting research using eye trackers. This paper presents the results of a study aimed to compare the outcomes from four different retrospective think aloud (RTA) methods in a web usability study: an un‐cued RTA, a video cued RTA, a gaze plot cued RTA, and a gaze video cued RTA. Results indicate tha...

A resurgence of interest in qualitative approaches to research in online consumer behaviour studies has spawned a need for structured approaches in the use of appropriate research techniques. A mixed method approach to research questions can often lead to a greater clarity of answer as well as exposing the researcher to new ‘tools of enquiry’. This paper describes a mixed method approach using ...

Globalization and increased communications have encouraged researchers to engage in international collaborations that enhance their knowledge opportunities. In this paper, I report the personal experiences, opportunities, benefits, challenges of collaboration from Iran through participation two research leadership topics (ILN project GLOBE 2020). describe opportunities for learning, sharing mee...

This paper deals with the problem of estimating an appropriate hand posture to grasp an object, from 2D object’s visual cues in a many-to-many (objects,grasp) configuration. A statistical learning protocol implementing vector-valued regression is adopted for both classifying the most likely grasp type and estimating the hand posture. An extensive experimental evaluation on a publicly available ...

'When it changed' and 'Litmus' have been two recent book projects from Comma Press, which brought together authors and scientists to produce anthologies of science-based short stories. Each story arose from the direct collaboration of one author and one scientist, and each was followed by a discussion of the motivating science. In this talk I will describe the interaction between myself as a sc...
