About the Project

This PhD project will focus on human-computer interaction for conversational agent design. The project aims to enhance the effectiveness, social bonding, trust and personalisation of conversational agents, to integrate and use them as learning companions. The potential outcomes of this research will include design guidelines and prototypes for conversational agents that will tackle the challenges and limitations of social conversational agents in the context of education and the human-AI interactions that can be developed.

Conversational agents and chatbots have seen a significant rise in the recent years, mainly due to the rapid development of natural language processing and artificial intelligence. These can take the form of embodied physical agents (e.g. Alexa, robots) or not embodied (e.g. chatbots). Industry technology titans, such as Amazon and IBM, have been investing hugely in chatbots and conversational agents to boost personal and team productivity. However, there are still challenges in deploying a socially competent chatbot and an area where these social, companion-style, and personalised conversational agent is particularly valued is education, formal or informal.

The project will involve the combination of Computer Science and Psychology to understand and explore how people interact and collaborate with conversational agents within a learning context. More particularly, the project will:

  • Explore how learners interact and collaborate with or through conversational agents in learning contexts and their expectations and needs for conversational agents as learning companions, taking a critical perspective on technical, social and cognitive implications.
  • Prototype, develop and explore new designs of conversational agents as learning companions that can revolutionise learning, collaboration and reflection.

Depending on the candidate’s experience the project will focus more heavily on one aspect or the other.

This project is well suited to a motivated and hard-working candidate with a keen interest in human-computer interaction, user experience, collaboration spaces, group behaviour and smart technologies. The candidate will join the NorSC Lab in the Department of Computer and Information Sciences

The Principal Supervisor for this project is Dr. Christina Vasiliou.
