1. Definition

Descriptors that are based on performance data from the Virtual Environment (objects and avatars) and have a form that is suitable for the Performance Status AIM to extract interpretations to determine Cue Points.

2. Functional Requirements

  1. Avatar Descriptors (may be driven by performers or algorithms)
    1. Avatar instance
    2. Descriptors of Avatar motion
      1. Position and Orientation (Spatial Attitude)
      2. Face and Gestures
      3. Eye tracking (Face Descriptors)
    3. Avatar audio activity
      1. Text uttered by Avatar.
      2. Avatar’s Audio Activity : oneOf: Speaking, Laughing, Clapping, Booing, Shouting, Singing
  2. Object Descriptors – all non-avatar objects and associated parameters including:
    1. Meshes with materials (terrain, foliage, etc.).
    2. Light sources and their parameters.
    3. Particles and their parameters.
    4. Effects such as fog, volumetric rays, fire, etc.
    5. Position and Orientation (Spatial Attitude) of all meshes, lights, particles, and effects.
    6. Other data (events, triggers, scene changes, etc.)
  3. Biometric descriptors of the performer 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.
