It is important to understand how a participant’s emotions vary throughout an experience. To help with that, Vempathy produces Metrics Graphs that show the range of a test participant’s valence, expressiveness, attention, and overall emotion throughout their experience.
In the Metrics Graphs you will notice wide bars with a lower limit and upper limit, which represent the low and high levels for each metric. Together the lower and upper limit allow you to identify the range. Somewhere in the middle you will find the average value for that test participant.
