Intelligent Interfaces


The Focus-Metaphor Approach is a novel concept for the design of adaptive and user-centric virtual environments which seeks to use a form of associativity to adapt the interface to the user whilst keeping one primary focus element and many secondary and peripheral focus elements.

Prior work on this approach - bachelor thesis and master thesis – has led to an upcoming full paper presentation at Interact 2005 Conference in September this year in Rome.

By building on the achievements so far, the research for my PhD shall embrace further theoretical investigations with the aim to realize concrete and promising scenarios.


It is the aim of the proposed project to apply the Focus-Metaphor Approach to the development of a large scale prototype. This online prototype will be a collaborative information environment using computer security as informational domain.

Over three years, the prototype environment as well as the general theory will run through an iterative development process conducting long term user studies and extensive in laboratory testing using eye-tracking equipment as well as physiological feedback to significantly improve the users’ experience of online information environments.
