In the whole, there has historically been a lack of sharing of this kind of technology. This is partly because generalising is hard, considering all types of robots and implementations possible. However, Lirec has to generalise as it's using a wide variety of platforms and needs to share as much as possible. | In the whole, there has historically been a lack of sharing of this kind of technology.

====Affective State==== | ====Affective State==== | ||
+ | |||
+ | The affective state is the " | ||
+ | |||
+ | As the affective state feeds into the appraisal, which in turn feeds into the affective state, a feedback mechanism is created, which helps the agent adapt to changing events. | ||
+ | |||
====Social Relations==== | ====Social Relations==== | ||
+ | |||
+ | This is where the agent models the relationships it has with other agents and humans, and the relationships other agents/ | ||
+ | |||
+ | The agent also needs an idea of how it's actions will change these relationships, | ||
+ | |||
+ | |||
====Models of others (Theory of Mind)==== | ====Models of others (Theory of Mind)==== | ||
+ | |||
+ | This is where the information regarding the agents and humans that the agent has met are stored. Each model will consist of a similar architectural form as the agent itself. This means that in order to estimate what another agent will think of an action, it can run an appraisal using it's model of the other agent, and look at the changes to it's affective state. The idea is that as more information is gathered (the more the agent gets to know it's user) the better these estimates will become. | ||
+ | |||
+ | The Lirec model is only recursive to one level, i.e. it does not attempt to model other agent' | ||

====Long term memory==== | ====Long term memory==== | ||
- | * Forgetting | + | |
+ | The long term memory is where the agent stores it's information on it's history of interactions with the user and other agents. This memory should be linked to all the decision making in the agent. | ||
====Short term memory==== | ====Short term memory==== | ||
+ | Where the agent keeps it's current goals, plans and action rules. |
