 LIREC aims to establish a multi-faceted theory of artificial long-term companions (including memory, emotions, cognition, communication, learning, etc.), embody this theory in robust and innovative technology and experimentally verify both the theory and technology in real social environments. Whether as robots, social toys or graphical and mobile synthetic characters, interactive and sociable technology is advancing rapidly. However, the social, psychological and cognitive foundations and consequences of such technological artefacts entering our daily lives - at work, or in the home - are less well understood. LIREC aims to establish a multi-faceted theory of artificial long-term companions (including memory, emotions, cognition, communication, learning, etc.), embody this theory in robust and innovative technology and experimentally verify both the theory and technology in real social environments.

-==Agent platforms, and migration between them==  +==Links== 
-An interesting feature of agents which need to build up a long term relationship with their users will be movement between different platforms. The platforms currently under investigation are:+

 +  
 +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.

-The scenarios are to be considered preliminary ideas for showcasing the technology developed for lirec, and highlight companionship and mostly exercise migration between devices.+In order to test and showcase the technology developed for lirec, several scenarios have been designed to promote companionship. These scenarios are shared between three of the research partners.

-In the whole, there is a lack of sharing of this kind of technology. This is partly because generalising is hard in this field, considering all types of robots possible. However, Lirec has to generalise as it's using a wide variety of architectures.+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 possible. However, Lirec has to generalise as it's using a wide variety of architectures and needs to share as much as possible.
  
-NASREM/NIST RCS - NASA + ESA use a generic system with their subcontractors.+While some existing architectures are available, none of them address the needs of lirec, given the focus:
