Notes om Benyon and Murray, written by Catherine Albers Most discussion took place around the issue of whether comparative or non-comparative analysis was "better"/ more valuable The comparison was biased by the screen Comparability is easily confounded by many factors Points up the need for long-term studies If the metrics for evaluating adaptive systems are good then is adaptivity good System and user can chase each other with adaptations Is it valuable to provide a baseline set back to an initial interface Measuring adaptation execution is different from measuring usability What is the basis of comparison for usability Usability is different from user satisfaction Technology has secondary effects which must be kept in mind during design Participatory design v. usability testing: is one "better" Evolving v. adaptive interface design Iterative interface development cycle
