I observed some difficulties that my project will encounter:
- The setup is a bit intrusive. The participant has to wear electrodes on part of their face and arms and movment is partially restricted. Too much movement will result in 'noisy' signals.
- There are several types of sensors measuring arousal levels (ECG, skin conductivity, respiration rates), but only one type measuring valence (EMG).
- Because of the above points, the stimulus must be of relatively short duration to limit movement and 'noise'.
