Usability Testing: Three Focus Groups
A: early adopter, technically literate, blogger, social networker, more interested in technical aspects than content & culture, hard to impress, opinion leader.Europeana Personas mapping: JUKKA
B: average internet user, above-average interest in culture, „technology is just a tool“ attitude.
Europeana Personas mapping: William & Maria
C: scientist, not used to computer based explorative methods, conservative use of media.
Europeana Personas mapping: Terese

Two user tests
• 1. Test in November 2010– Is the interface useful (for a general public)?
Accessibility, Learnability, Efficiency, Correctness– Does it provide a new scientific approach / method
Appropriateness, Quality, Explorative methods– Tests guided by facilitator
• 2. Test in March 2011– Complex tasks/puzzles– Had to be solved alone– Tutorial video as a guided tour
