-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.+<blockquote>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.

-Key areas of the research will focus on are:+http://www.lirec.org 
 +See also [[Project Lirec]]
  
-==Long term companions== +=====Theory=====
-Robots and agents which build up a long term relationship with their users. +
  
-==Agent migration==  +  * [[Models of Social Intelligence]] 
-In order to maintain a long term companionship, the agent will be required to move between different forms. Forms currently under investigation are: +  * [[Theory of Mind in Robotics]] 
-  * Mobile robot +  * [[Psychological Models of Empathy]]
-  * Fixed robot +
-  * Handheld device +
-  * Fixed graphical system+
  
-This migration between these devices, and how people relate to this migration is a core element of the research.+=====Ethics=====
  
-===Scenarios===+  * [[Lirec Ethical Issues]]
  
-The scenarios are to be considered preliminary ideas for showcasing the technology developed for lirec, and highlight companionship and mostly exercise migration between devices.+=====Architecture=====
  
-==Heriot Watt==+See [[Lirec Architecture]] for an overview of the planned technical structure of the project. 
 +[[Yet Another Robot Platform]] is part of/inspiration for some of the lirec architecture. 
 + 
 +=====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 between 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. 
 + 
 +=====Scenarios===== 
 + 
 +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.

-===Architecture===+====The University of Hertfordshire==== 
 +  - Fetch and carry, to help with physical impairment or provide convenience 
 +  - Cognitive prosthetic - memory aid for tasks 
 +  - Telepresence card player - a robot mediates play between two people 
 +  - Teaching proxemic preferences - a robot learns where to be relative to the user in different situations 
 +  - Travelling companion - agent migration, to stay with user during home, work, shopping
  
-Has to: +=====Experimental testing=====
-  - Run on very different platforms +
-  - Reuse code across these platforms +
-  - Support migration at runtime between platforms+
  
-Platforms can consist of 4 main types, mobile robot, fixed robot, handheld device or fixed graphical system. Each has it's inherent restrictions. +All scenarios developed are to be experimentally tested and showcased to the public.
  
-==Existing robot architectures== +TODO
-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.+
  
-NASREM/NIST RCS - NASA + ESA use a generic system with their subcontractors.+=====Software=====
  
-==Methodology== +  * [[lirec:FAtiMA]] 
-In the past there have been 2 broad approaches to robot design: +  * [[lirec:Greta]] 
-  * Heirarchical, model based planning = expensive to maintain accurate world state model +  * [[lirec:development questionnaire results]] 
-  * Behavioural approach = less state, local decisions, liable to local minima, opaque to program +  * [[lirec:partner competency sharing]] 
-This can be summed up as predictive vs reactive.+  * [[lirec:competency software]]
  
-Current thinking is to use a hybrid approach, example BIRON. Where the predictive constrains the reactive to combine local decisions with a world model.+=====Meeting notes=====
  
-The architecture will consist of 3 layers of abstraction: +  * [[lirec:Feb20WP9Meeting]] 
-  * Level 1 - device layer, architecture dependant +=====Links=====
-  * Level 2 - architecture dependant -> logical mappings +
-  * Level 3 - ION, device independant+
  
-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.+[[Lirec Work Packages]]
  
-Example competencies: +[[Lirec Articles]]
-  * Face finding +
-  * Expression recognition +
-  * Text to speech +
-  * Obstacle avoidance+
  
-YARP+[[http://eris.liralab.it/yarp/|YARP]] is a good example of sharing code in this way on a Linux platform.
