Context: Emotions play an important role in people's daily lives, thus emotional regulation is crucial in human development, as it determines our behaviors and decisions, as well as our physiological responses. Through two different virtual environments with a speech performed by a digital human, we expect to elicit emotions with different valence (happiness and anger). The virtual scenarios used to elicit the emotion of happiness and anger were a natural outdoor forest environment and a subway car, respectively.

Objective: To obtain the physiological reaction (the electrical activity of the brain, galvanic skin response, blood volume pulse and temperature) and psychometric response (Emotion Regulation Questionnaire, Self Assessment Scale questionnaire and questionnaires related to the participant's perception of the digital human such as identifying the specific Emotion Facial Action Coding System, as well as a Likert scale about the familiarity, friendliness, attractiveness, and alikeness of the digital human) of 20 subjects elicited by an emotional speech of a digital human into two different virtual environments , where two emotions with opposite valence were aimed to induced: anger and happiness.

Limitations: Due to external artifacts physiological data of 9 participants was discarded.

Technical information:

The wearable EEG headset Unicorn Hybrid Black was used for the recording of the brain activity at 250 Hz. In addition, the E4 wristband was used for the recording of the Autonomous Nervous System responses:

- Galvanic skin response was recorded at 4Hz.
- Blood volume pulse was recorded at 64 Hz.
- Temperature was recorded at 4Hz.
