Even though the emotional state is increasingly taken into account in scientific studies aimed at determining user experience of user acceptance, there are still only a few normalized tools.

Thus, we propose a prototypical tool called SYM (Spot Your Mood) as a new tool in user mood determination to be used in many different situations.
