QUASS is a new tool which has been developed by Anna Bouch at UCL. The tool consists of a sliderbar which allows users to rate the quality of either audio or video during the session. This allows us to see users' peception of quality at any one point in time during the session, which means that we can see the effect of fluctuations of quality during a session.
QUASS starts up with two windows, a Participant Information Window and a QUASS Main Window. You must fill out the details in the Participant Information Window before you begin rating.
To begin rating, press the Start button in the QUASS Main
To stop rating, press the Quit button in the QUASS Main Window.
To rate, move the slider bar up or down depending on the how you perceive the quality of the session. The top, marked with a +, indicates quality which is adequate for the session; the bottom, marked with a -, indicates quality which is not adequate for the session. REMEMBER TO PRESS START BEFORE YOU BEGIN RATING.
QUASS produces a file named QUASS followed by a number, e.g. QUASS896695705. Please send the file to Louise (email@example.com) after the session.
