Adapting A Psychophysical Method To Measure Performance And Preference Tradeoffs In Human-Computer Interaction

An experimental methodology for contrasting certain design alternatives and quickly determining user preferences and performance tradeoffs is presented. It is shown how this experimental paradigm, used for psychophysical measurement, may be applied to the field of human-computer interaction. Where it can be applied, it promises a relatively quick determination of user preference and performance characteristics and tradeoffs on these measures with variation in parameters governing the user situation. Because the methodology is within-subject, it may also facilitate the study of individual differences.
