Agents that remember can tell stories: integrating autobiographic memory into emotional agents
Ho, W.C.; Dias, J.; Figueiredo, R.; Paiva, A. (ACM Press, 2007)For the past few years many new applications are being developed featuring interactive environments populated with autonomous virtual agents capable of acting according to their goals, beliefs and even social relations. ... -
AMIA: A knowledge representation model for computational autobiographic agents
Ho, W.C.; Watson, S.; Dautenhahn, K. (Institute of Electrical and Electronics Engineers (IEEE), 2007)This paper describes a hierarchical design for knowledge representation in computational autobiographic memory. This model is named AMIA (Autobiographic Memory for Intelligent Agents). Inspired by research in human ... -
Assessing the performance of different behavior selection architectures in a large and complex virtual environment
Ho, W.C.; Avila-Garcia, O.; Nehaniv, C.L. (Institute of Electrical and Electronics Engineers (IEEE), 2005)We compare the performance of autonomous agents with three different behavior selection architectures (Static-Threshold, Winner-Takes-All and Voting- Based) in terms of survival in a large and complex dynamic virtual ... -
Autobiographic agents in dynamic virtual environments - performance comparison for different memory control architectures
Ho, W.C.; Dautenhahn, K.; Nehaniv, C.L. (Institute of Electrical and Electronics Engineers (IEEE), 2005)In this paper, we extend our previous work in investigating the performance of different autobiographic memory control architectures which are developed based on a basic subsumption control architecture for Artificial Life ... -
Autobiographic knowledge for believable virtual characters
Ho, W.C.; Watson, S. (2006)It has been widely acknowledged in the areas of human memory and cognition that behaviour and emotion are essentially grounded by autobiographic knowledge. In this paper we propose an overall framework of human autobiographic ... -
Comparing different control architectures for autobiographical agents in static virtual environments
Ho, W.C.; Dautenhahn, K.; Nehaniv, C.L. (2003) -
Computational memory architectures for autobiographic agents interacting in a complex virtual environment : a working model
Ho, W.C.; Dautenhahn, K.; Nehaniv, C.L. (2008)In this paper, we discuss the concept of autobiographic agent and how memory may extend an agent's temporal horizon and increase its adaptability. These concepts are applied to an implementation of a scenario where agents ... -
Designing an Educational Game Facilitating Children’s Understanding of the Development of Social Relationships Using IVAs with Social Group Dynamics
Ho, W.C.; Dautenhahn, K. (2009)Social relationships are fundamentally important to humans. Children are born into a family social structure and gradually they become part of a wider social structure including peers, in which each individual’s relationships ... -
Episodic memory visualization in robot companions providing a memory prosthesis for elderly users
Ho, W.C.; Dautenhahn, K.; Burke, N.; Saunders, J.; Saez-Pons, J. (IOS Press, 2013)The goal of home care robots is to help elderly people to age in their own homes. Ageing people who are otherwise quite healthy may suffer from memory loss and consequently decrease their independence because the memory ... -
I know what I did last summer: autobiographic memory in synthetic characters
Dias, J.; Ho, W.C.; Vogt, T.; Beeckman, N.; Paiva, A.; Andre, E. (2007)According to traditional animators, the art of building believable characters resides in the ability to successfully portray a character’s behaviour as the result of its internal emotions, intentions and thoughts. Following ... -
An Initial Memory Model for Virtual and Robot Companions Supporting Migration and Long-term Interaction
Ho, W.C.; Lim, M.Y.; Vargas, P. A.; Enz, S.; Dautenhahn, K.; Aylett, R. (Institute of Electrical and Electronics Engineers (IEEE), 2009)This work proposes an initial memory model for a long-term artificial companion, which migrates among virtual and robot platforms based on the context of interactions with the human user. This memory model enables the ... -
Modelling human memory in robotic companions for personalisation and long-term adaptation in HRI
Ho, W.C.; Dautenhahn, K.; Lim, M.Y.; Du Casse, K. (IOS Press, 2010)This paper investigates issues of robot's personalization and long-term adaptation in human-robot interaction (HRI). It demonstrates the design and first technical implementation of a HRI showcase in the Robot House at ... -
Reducing the cost of robotics software : SAMGAR, a generic modular robotic software communication architecture
Du Casse, K.; Koay, K.L.; Ho, W.C.; Dautenhahn, K. (Institute of Electrical and Electronics Engineers (IEEE), 2009)Code reuse in advanced robotics can be problematic due to the wide spectrum of robotic projects and little standardization. Although, in some cases, there are standardisations and tools that can be used, such as YARP, there ... -
Sharing memories: an experimental investigation with multiple autonomous autobiographic agents
Ho, W.C.; Dautenhahn, K.; Nehaniv, C.L.; Te Boekhorst, R. (IOS Press, 2004)The overall aim of our work is to develop a generic adaptive control architecture for autonomous intelligent agents. In our previous work we showed how a single agent's survival can benefit from autobiographic memory. In ... -
A study of episodic memory-based learning and narrative structure for autobiographic agents
Ho, W.C.; Dautenhahn, K.; Nehaniv, C.L. (The Society for the Study of Artificial Intelligence and the Simulation of Behaviour (AISB), 2006) -
Supporting narrative understanding of children with autism: A story interface with autonomous autobiographic agents
Ho, W.C.; Davis, Megan; Dautenhahn, K. (Institute of Electrical and Electronics Engineers (IEEE), 2009)Recent studies in education for children with autism demonstrated that computer assisted learning can increase children's narrative understanding. However, software interfaces which include autonomous intelligent agents ... -
