As a follow-up to the previous post, we'd like to evaluate the usability of our screencasts systematically. We know we're not the first (or ten-thousandth) people to want to do this, so I went looking for procedures we could borrow. The University of Maryland's Questionnaire for User Interface Satisfaction (QUIS) looks like just what we need:
(QUIS) is a tool developed by a multi-disciplinary team of researchers in the Human-Computer Interaction Lab (HCIL) at the University of Maryland at College Park. [It] was designed to assess users' subjective satisfaction with specific aspects of the human-computer interface. The QUIS team successfully addressed the reliability and validity problems found in other satisfaction measures, creating a measure that is highly reliable across many types of interfaces.
Excellent! Until you click on the Licensing link, and discover that the questionnaire is $750 for commercial users and $200 for academics. *sigh*
