A spoken dialogue system using virtual conversational agent with augmented reality
Shinji Miyake, Akinori Ito · Asia-Pacific Signal and Information Processing Association Annual Summit and Conference · 2012
We have developed a spoken dialogue system using virtual conversational agent with augmented reality. The proposed system has architecture based on question and answer database that contains many question and answer pairs. Additionally, we have developed two agents displayed using augmented reality, which behave as avatars of objects to be operated. We evaluated user's impression as well as response accuracy of our proposed system. As a result, the existence of an agent increased user's feeling of vividness of conversation and easiness to talk to the system. In addition, the system with an agent showed better response accuracy than the system without agents.
