+ | LIREC aims to establish a multi-faceted theory of artificial long-term companions (including memory, emotions, cognition, communication, | ||
+ | |||
+ | ==Agent platforms== | ||
+ | |||
+ | The platforms currently under consideration for long term companions are: | ||
+ | * Mobile robots | ||
+ | * Fixed robots | ||
+ | * Handheld devices | ||
+ | * Fixed graphical systems | ||
+ | |||
+ | ==Migration== | ||
+ | |||
+ | An interesting feature of the research is migration betwen these platforms. Agents which need to build up a long term relationship with their users will have to switch forms depending on the needs of the user at different times. The migration of an agent between devices, and how people relate to it, is a core element of the research. | ||
