Notes: - in the end every group has defined/classified the user: - Classification in Petters paper (professionals, non-users, ) - development of a graph based on: - computer knowledge - domain skills - reason for creation (for living, not for living) - they added semi-professional users (advanced users) - shortest path approach (they don't care of technology...) - Methodology: - traditional methods - online research: - it is important to encourage elder people - today only for young people - lead users can generate new ideas; then non-pofessional users can evaluate - The idea is that non-professional users might not use online research and you might have to use traditional methods (focus groups, surveys); while lead users can evaluate with online tools - The interesting thing of online tools is that they bring together users and researchers [but still researchers cannot disturb the final results] - if you are going to have users during all the process... you need to motivate them (maybe by peer-to-peer evaluation?) - some problems of online tools: the researchers can control less the environment [there is a trade-off between traditional and online tools] - for example, you can get a lot of users and a huge amount of data - on the other hand, structured evaluation can consider many troubles (cognitive models)
