USABILITYAnalysis of the
INQUIRY
- Objective + subjective information- No distance observation and registration- Symmetric: researchers = participants- Sincerity and confidence- Technological mediation*
- Difficulty to get the objectivity and the real immersion.- Uncontrollable circumstances- Limits are not clear- Real online identity?- Techonological mediation*
Technology is social
Identity + sociability onlineSocial organization in virtual contexts

Direct observation Interviews
INSPECTION
according to Jakob Nielsen
Analysis of the interfaceto detect possible interaction errors
Cognitive Walkthroughs.
Heuristic evaluation.
Nielsen's heuristics (and more)
-The analysis of usability can saymany things about the web andinteraction system.-It's an instrumental approach
-the analysis of the usability can hide some elements. -This methodology cannot say WHY. It is focused on saying WHAT.
Collecting quantitativedata from users and getting information about them
Field observation
Interviews/focus group
-Bruce Tognazzini's 16 principles-Ben Scheiderman's 8 golden rules-Lund usability maxims
These are qualitative methodsbut the answers can be quantified
More a DISCOVERY process than a EVALUATIVE process
