1. Definition
The focused status data obtained by observing the individual and collective behaviour of Participants in the Virtual Environment by interpreting the descriptors, per the current Cue Point, including behaviour, Emotion, Cognitive State, and Social Attitude, as needed by the Action Generation AIM to service the current Cue Point.
2. Functional Requirements
VE Participant Status includes only those VE Participant Descriptors that are relevant per the current Cue Point Conditions and Actions for hand over to the Action Descriptor Generation AIM as well as collective behaviour of Participants relevant to current Cue Point Conditions and Actions.
