Introduction to the Experiment and Questionnaire - 3DTV: Processing and Transmission of 3D Video Signals - page 205

The assessment will take place on a paper provided to you on the evaluation
day. The scale given to mark your scores is shown in Figure B.2. Assess all
the sequences in terms of their perceptual quality attribute (i.e. Image quality
or depth quality or overall 3D quality). You are expected to use the full range
of the scale. The labels above the scale serve as a reference, i.e. the bottom of
the scale is the lowest and the top is the highest score possible.
Before the experiment begins a short training session will take place.
Through this training you will get acquainted with the videos that are used
in the experiment.
It is important to watch the whole video, because the differences are not
the same for every video. You are allowed to move the position of your head
only by a centimetre to the left and to right to get a better view of the image.
If you have any questions, please ask them during the training session. After
the training session the experiment begins. The experiment consists of two
15-minute sessions. In between there will be a short break of 10 minutes.
Again, thank you for participating in this experiment.
