Study on cooperative action supplementation in metaverse.

1.Emotion and connection attribute

In emotions that are the origin of action by physiological and emotional behavior, in social situations, there are often behavioral differences due to their connections. An emotional reaction occurs according to situations where this is also unconscious.

As an element for emotion to activate.

    Cause
    Distance to object
    Reaction time
    Relationship with influenced person at the same time.

As the cause varies depending on the degree of risk, the influence varies depending on the degree of life and death involvement.
Regarding distance, physical and psychological distances are decided according to the degree to which the person perceives.
Regarding the lapse of time, it is largely due to relaxation of the sense of crisis due to such situation judgment such as observation and judgment of the situation.

However, when this becomes a virtual space, the circumstances change completely, the operation is forced to all actions, the reaction like emotion can not be expressed, and the reaction behavior of operation naturally becomes slow.

2.Application to metaverse environment

The function for reproducing the element for recognizing on the metaverse is as follows.

    Reaction action
    Sutation
    Strength (Relationship)
    Between (elapsed time)
    A feeling

3.It is necessary to reproduce these in the metaverse.

In addition to emotion when we implemented it in the metaverse we also fed back to the player's expression as a nonverbal expression method.
In fact, we prepared emotion sensor for players and classified them as "pity," "disgust", "joy", "surprise", "favor", "shame", "anger", "fear". Regarding category classification, Aoyama Gakuin Harare Laboratory "Emotions and Will Analysis" was consulted ~ Categories are cheerful, angry, sorrowful, shameful, disgusting, reluctant, depressed, surprised but the target animation Since there is no such thing, some emotional expressions have been omitted.

Each emotion category was prepared and an alphabetic character string of an emotional command was generated from the emotional degree at that time based on the cause.

The emotional sensor (now, the degree of strength of each of the four stages) varies depending on factors and is pooled for a certain period of time to the player. When certain external factors are triggered, the extent of the influence of the original external factor which is uniformly attenuated by other factors is never exceeded. It is set so as to regain calmness and decay with time as time elapses.

As for external factors, the following influences (currently the influence range is limited to within 4feet)
    Surrounding environment
    The opponent's speech (My staff it calling emotional ball.)
    Emotion of the opponent (emotion transformer)

The status of the emotional sensor was made to change by comprehensive evaluation of these external factors. Based on that, finally create facial expressions.The degree of influence due to psychosomatic state and intimacy (lnfluence rate).
The degree of influence by the other person is also influenced by the state of himself and the degree of infinity (influence rate) of the other party.
Digitizing this mutual relationship is decided by how far past, influenced each other.Favorability rating for objects in the metaverse.
There are many objects and areas in the metaverse, and likes, dislikes or indifference for each can be set. This means that other players will be subject to evaluation without exception.
In the virtual world it was difficult to convey feelings, but I think that it is an interesting attempt as nonverbal communication.
