- This application is intended primarily for use in experimental research, investigating music and emotion. The purpose is to collect continuous ratings of either perceived or felt emotion, whilst a piece of music is played simultaneously.
- Launch
RUN.pyto run the application. When prompted, enter a participant ID - this can contain any alphanumeric characters. NOTE: Entering 0 will cause the application not to log data. - A dialog box will open, allowing a sound file to be selected (supported formats: WAV, MP3, OGG). For convenience, demo music (non-copyrighted) is included in the 'Resources' directory
- Once a sound file is chosen, the main interface will now open. The user can drag and drop the ball to any position in arousal-valence space, in order to register their current emotional response.
- Once done, simply close the window, and the data will be saved automatically. Data are stored in a CSV file in the 'Data' directory. By default, arousal and valence ratings are saved 10 times per second.
- To take a continuous mood rating without playing any sound, use
RUN_NO_SOUND.pyinstead. To take a single 'snapshot' measure of mood (also without sound), useRUN_SNAPSHOT.py. - Example instructions ('PARTICIPANT_INSTRUCTIONS.docx') are included, featuring a screenshot of the application. Obviously, these might need to be adapted depending on what the particular experiment involves.
- Further instructions for experimenters are also included ('EXPERIMENTER_INSTRUCTIONS.pdf').
