Helen Purchase on An Exploration of Interface Visual Aesthetics

Speaker: Helen Purchase, University of Glasgow
Title: An Exploration of Interface Visual Aesthetics
Abstract:
The visual design of an interface is not merely an ‘add-on’ to the functionality provided by a system: it is well-known that it can affect user preference, engagement and motivation, but does it have any effect on user performance? Can the efficiency or effectiveness of a system be improved by its visual design? This seminar will report on experiments that investigate whether any such effect can be quantified and tested. Key to this question is the definition of an unambiguous, quantifiable characterisation of an interface’s ‘visual aesthetic’: ways in which this could be determined will be discussed.

About Helen:
Dr Helen Purchase is Senior Lecturer in the School of Computing Science at the University of Glasgow. She has worked in the area of empirical studies of graph layout for several years, and also has research interests in visual aesthetics, task-based empirical design, collaborative learning in higher education, and sketch tools for design. She is currently writing a book on empirical methods for HCI research.

The Results Delusion

Abstract:

It is often said that any subject which requires the word ‘science’ to be placed somewhere in its name, is unlikely to be very scientific. This is unfortunately far too true for systems research in general. Every systems conference, papers are presented which show significant speedups over previous approaches to problem X, but these improvements are rarely replicated in output from industry. Why? The unpalatable answer is that a significant amount of systems research is the result of self-delusion, bad science and, I suspect occasionally, fraud.

Standards of scientific rigour in CS often fall well below what would be taken for granted in other sciences – particularly with regard to measurement of results, statistical analysis and replicability of results. I would like to do something about this, and will be presenting the idea for a new CS journal, which focuses on this exact problem. Oh, and peer review is gone too! Pitfalls abound. Would love to hear your comments, objections and advice.
