Results from 'Thinking Aloud' interviews for ViRR Release 3[edit]

Terms and definitions[edit]
Issues
Indicate where users were hesitating, asking, put a comment or missed the right action at the first attempt. (A hint for User Interface Engineering where problems exist and if they can be related to wording, process or position). Issues are rated as Minor, Serious or Failed but do not count to the task as souch. They only provide hints to the interface engineering team how to judge severity of issues.
Failed
The task couldn't be completed with the interface. This is the case when users get lost within the interface, do something wrong or can not continue because something is missing.
OK
The task leads to a valid result. This is the case when no step shows a single 'Failed'. It does not mean that single steps can have issues of type serious or minor.
Charts[edit]
These are less important tasks. They are performed to as a warm up for participants and are usually carried out flawless.
Summary[edit]
Measures taken from interviews do not lead necesserily to a solution of the problem in one go. Old issues need to be tested again. As R4 comes with a new interface it needs to be tested completely.
