Enquiries and Directives
sage can be transformed into a structured form of
the original message, analysis can occur.
An Enquiry is a question directed to one or many
partners with the expectation of some form of
verbal response. A Directive is a request for
some form of response by one or more partners.
An Enquiry is a special type of directive where
the expected response is specifically verbal in
nature. An enquiry or directive is required in the
case of insufficient information to address the
current collaborative exchange. This is particu-
larly important when various FEPs engaged in a
collaborative process have access to different sets
of knowledge. In order to achieve an outcome,
information has to be requested and shared with
the rest of the group. This process of knowledge
sharing also grows each partner's set of indirect
test data for statement assessment.
The Analysis subsystem supports the process of
taking interpreted information from the Percep-
tion subsystem, analyzing the input and providing
information for the Decision-Making subsystem
to formulate a response based on the information
The analysis phase can draw upon knowledge
of previous events to help infer context. By the
end of this process, the message structure has been
associated with definitions and meanings that have
been stored in the cognitive data. Consequently,
this message shall also be recorded, as well as the
resulting decision and action for future reference.
Once each type of message has been analyzed, a
decision must be determined as to what response is
to be taken. By this point, the sensed message has
been classified as one of the following message
types: A Statement, Enquiry, Directive or Action.
An Action is a non-verbal message enacted by an
external party (another partner or the computer
game itself) and sensed by the partner's sensors.
Actions are performed upon objects within the
computer game environment. An action changes
the state of an object from one form to another.
Making a Decision
A Statement is a communication between one or
more partners that expresses a perceived observa-
tion made by the originating partner. Statements
therefore must be tested as part of the decision-
making process. Statements may be directly or
Direct testing relies on the partner being able to
perform tests upon the statement and recording the
result. Indirect testing relies on secondary sources
of information that the partner has collected from
The response to each type of message is the
responsibility of the Decision-Making subsys-
tem. The responses that are available include
Statements, Enquiries, Directives, Actions or No
Response at all.
Decisions can be made using a wide variety
of methods. In the context of the play scenarios
presented here, the decision-making subsystems
were able to incorporate a number of problem
