The following PhD research studentships are available at Oxford Brookes
University, School of Computing and Mathematical Sciences
1. An investigation into the process of strategy building at the
human-computer interface and development of automated support
mechanisms for those with poor memory'
Supervisors: Mary Zajicek and David Duce
We have built a special front end to BrookesTalk, our Web browser for blind and
partially sighted users, for elderly users with poor memory. The system speaks
to users and reminds them where they are in their interaction and tells them
where they can go from here. Initial evaluations of the system are very
promising.
The suggested PhD work would involve applying current strategy building and
memory loss theory to improving interface design and establishing principles
for interface design for elderly users.
2. Formal Modelling and Accessibility
Supervisors: David Duce and Mary Zajicek
One of the key issues in the design of web-based information is accessibility -
making web-based systems usable by people with disabilities. This may mean
people who have permanent disabilities, such as partial sight, or "fully-able"
people working in environments where use of some of the senses is impaired.
There is a growing body of guidelines for the design of such systems (for
example guidelines published by the World Wide Web Consortium), based largely
on practice and experience. The aim of this project is to explore theoretical
foundations for the design of such systems and in particular the extent to
which it is possible to reason mathematically about the design of such systems.
This will build upon research initiated by David Duce, David Duke (University
of York), Phil Barnard (MRC Cognition and Brain Sciences Unit, Cambridge), and
Jon May (University of Sheffield) , called Syndetic Modelling, which is aiming
to bring together models of human cognition and computer systems within a
common mathematical framework to enable reasoning about the conjoint behaviour
of human user and computer system.
3. Remote QoS Monitoring for Multicast Audio and Video
Supervisors: Frank Ball and David Duce
With applications such as Video Conferencing in which video and audio streams
are being multicast over the network, it is often very difficult for the source
to be aware of the quality of reception at the various destinations. However,
such knowledge may be useful, and in many cases very important, for assessing
the effectiveness of the application at particular instances of time. This
project will be concerned with developing network monitoring and measuring
techniques that can aid the application to assess the quality of reception at
various destinations. An important consideration of this work will to match
aspects of perceived quality with numeric measurements of network performance
