1. Definition

Descriptors that are based on Participant data form the Virtual Environment (objects and avatars) and have a form that is suitable for interpretation (e.g., Face and Gestures) in addition to providing Descriptors to determine cue points.

2. Functional Requirements

Components from the virtual environment: Avatar behaviour

  1. Spatial position of Avatar participants
    1. Per area/zone
    2. Ground/air
  2. Descriptors of Avatar elements (skeleton)
    1. Limb, head motion
    2. Eye gaze direction
    3. Avatar appearance (shape, clothing, et.)
  3. Avatar audio activity
    1. Text uttered by Avatar.
    2. Avatar’s audio activity:
      1. Text uttered by Avatar.
      2. Avatar’s audio activity:
        1. Speaking
        2. Laughing
        3. Clapping
        4. Booing
        5. Shouting
        6. Singing
  4. Biometric descriptors of the participant represented in the Virtual Environment.
    1. Heart rate and Heart rate variability (HRV).
    2. Brain state from EEG data (delta, theta, alpha, beta, gamma).
    3. Galvanic Skin Response (Electrodermal Activity).
    4. Myoelectric intensity per electrode site.
    5. Skin temperature.
