During conventional usability testing, the screen and either the face or the hands of the test person is recorded. Each recording is then analyzed with The Observer Video-Pro and predefined events and tasks are logged. For presentation purposes, video highlights are produced as MPEG-1 clips. In quantitative studies, summary statistics (task completion times, error rates) are exported to Excel and to proprietary software for hypothesis testing, mostly using re-sampling statistical methods. The lab is used for both teaching usability evaluation methods and for research.

The interaction space is a large room which can be subdivided by curtains and low, movable walls. This makes it suitable for studying both group interaction and conventional one-user studies.

 

We have chosen a combination of analogue and digital video recording and usually combine more than one view in our recordings.
