Cardiff: User satisfaction vs. user efficiency: dealing with conflicting demands (Tuesday 15 Feb. 2005)
Effectiveness, efficiency and user satisfaction are the three elements that ISO9241 defines as essential to usability. But what can the designer/developer do if a usability study shows the most effective solution is wholly disliked by users?
Dr Alan Salmoni will be sharing some insights based on his research and recent observations.

Dr. Alan James Salmoni recently completed a Ph.D. at Cardiff University in
human-computer interaction. The topic of his thesis focused upon how people
make relevance decisions when they are given insufficient information to
make consistently accurate decisions.
He has also programmed a computer application for statistical analysis
(SalStat) which is open source. Principles of HCI were used in constructing
the interface, and it was tested using GOMS analysis (Card, Moran, Newell,
1983). The current download has an interface that works faster than many
other of the commercial applications (Statistica, Minitab, S.P.S.S. and
S.A.S.) being beaten only by StatView. A new interface is being designed
which beats even this. SalStat was programmed in response to problems that
Alan observed when teaching psychology undergraduates how to do statistical
analysis using existing packages, and hopefully should allow beginners to
perform analyses more easily.
