Investigating children's eye-movements: Cause or effect of reversing ambiguous figures? (2007)
Presentation / Conference Contribution
Wimmer, M., & Doherty, M. (2007, August). Investigating children's eye-movements: Cause or effect of reversing ambiguous figures?. Presented at 29th Annual Cognitive Science Society, Nashville, Tennessee, USA

We examined whether eye-movements play a significant role in perceiving both interpretations (reversing) of ambiguous figures such as the duck/rabbit (Jastrow, 1900). In an eye tracking study we investigated 3-, 4- and 5-year-old children’s reversal... Read More about Investigating children's eye-movements: Cause or effect of reversing ambiguous figures?.

Testing and Sampling Parallel Systems (2007)
Presentation / Conference Contribution
Kerridge, J. (2007, July). Testing and Sampling Parallel Systems. Presented at 30th Communicating Process Architectures Conference, CPA 2007, University of Surrey, Guildford, Surrey, UK

The testing of systems using tools such as JUnit is well known to the sequential programming community. It is perhaps less well known to the parallel computing community because it relies on systems terminating so that system outputs can be compared...

Collecting Pedestrian Trajectory Data In Real-time (2007)
Presentation / Conference Contribution
Kerridge, J., Keller, S., Chamberlain, T., & Sumpter, N. (2005, September). Collecting Pedestrian Trajectory Data In Real-time. Presented at Pedestrian and Evacuation Dynamics 2005, Vienna

The ability to collect pedestrian flow data, without the need for subsequent post-processing and analysis to extract measurements such as density and flow rate is a goal, which up to now, has proved infeasible on a large scale for a number of reasons...
