Vempathy blends together three different data streams from your participants reactions: facial expression, verbal inflection, and contextual sentiment. The contextual sentiment focuses on what was said, the verbal inflection focuses on how it was said, and the facial expression helps determine the emotion of the participant as they are completing the task.
The overall emotional score integrates our expressiveness, attention, and valence measures to give an overall score of the feeling a participant has when completing a task. For tasks with a low emotional score, this indicates a negative emotional reaction to completing the task. Inversely, if a task shows a high emotional score, the participants experience a positive emotion while completing the task. Depending on the objectives of your study, you may focus on one or the other.
A high expressiveness score indicates the participant’s facial muscles appear to be active and expressive during the task. This does not mean that participants with a low expressiveness score are disengaged, rather their facial expressions aren’t showing enough activity to indicate a high level of expressiveness.
A high attention score indicates the participants facial angles indicate a focus on the screen they are looking at. A low attention score would indicate that a participant is not focusing to the screen and may be focusing away from the task at hand, or possibly at something offscreen.
A positive valence is associated with positive emotions, such as joy or delight for example. A negative valence is associated with emotions such as anger and fear for example. The valence of a particular task can indicate the emotional reaction of the participant’s experience.
