-LIving with Robots and InteractivE Companions
+==== LIving with Robots and InteractivE Companions ====
 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.
-Key areas of the research will focus on are:
+==Agent platforms, and migration between them==
+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:
+  * Mobile robots
+  * Fixed robots
+  * Handheld devices
+  * Fixed graphical systems
-==Long term companions==
+This migration between these devices, and how people relate to it, is a core element of the research.

-==Agent migration==
-In order to maintain a long term companionship, the agent will be required to move between different forms. Forms currently under investigation are:

-  * Handheld device

 ==Methodology==
 In the past there have been 2 broad approaches to robot design:
-  * Heirarchical, model based planning = expensive to maintain accurate world state model
+  * Hierarchical, model based planning = expensive to maintain accurate world state model
   * Behavioural approach = less state, local decisions, liable to local minima, opaque to program
 This can be summed up as predictive vs reactive.
-Current thinking is to use a hybrid approach, example BIRON. Where the predictive constrains the reactive to combine local decisions with a world model.

 The architecture will consist of 3 layers of abstraction:
-  * Level 1 - device layer, architecture dependant
+  * Level 1 - device layer, platform dependant
-  * Level 2 - architecture dependant -> logical mappings
+  * Level 2 - platform dependant -> logical mappings
-  * Level 3 - ION, device independant
+  * Level 3 - ION, platform independent
-Level 2 will provide a reference architecture with modular capabilities called competencies. Not all competencies will make sense for all architectures, and different implementations of the same competency may exist.
