Introduction to the
Experiment and
Questionnaire

The handout given to subjects, before the test, explaining the procedure of
the experiment is given in Section B.1. The questionnaire given to the subjects
on the day of the experiment is given in Section B.2.

B.1 Introduction to the Experiment

Thank you for participating in this experiment.
In this experiment, you are asked to assess some 3D video sequences in
terms of an evaluation attribute (i.e. Image quality or depth quality or overall
3D quality), which will be clarified for you. The sequences will be displayed
as shown in Figure B.1. 1 The images/sequences are displayed on a 3D screen.
Prior to each video sequence, a grey screen is displayed for 3 seconds. Each
video sequence will be displayed for 10 seconds.
Video sequences A and B will be displayed on the screen consecutively.
Then the same sequences will be repeated again. With the start of the
repetition, you can start ranking individual sequences for their perceived
quality attribute. In order to complete the assessment process a grey scale will
be displayed for another 5 - 11 seconds after repeating the video sequences.

1 When the SSCQS method is used instead of the DSCQS method, the handout is changed
accordingly.
