By constructing dialogue systems, we conduct research to understand how humans can engage in dialogue, what the fundamental principles of dialogue are, and more. Not only do we build dialogue systems, but we also analyze human-to-human conversations from various perspectives to approach the essence of dialogue.

The Higashinaka Laboratory has three project teams, and members belong to one of these teams to conduct their research.

Task-Oriented Dialogue System

Current dialogue systems have performance limitations, making it challenging to implement even simple tasks (such as providing information or sales assistance). This project aims to achieve systems that can reliably accomplish tasks by re-evaluating the construction of dialogue systems from scratch and utilizing android robots and multimodal processing.

Collaborative Dialogue System

We develop new models that enable computers and humans to communicate through dialogue and perform model-based analysis and modeling of human-to-human dialogue and collaborative work. Using various collaborative work tasks as subjects, we create systems that can perform collaborative work through dialogue.

Enhancement of Human Dialogue Capabilities

Dialogue services are conducted everywhere. By enhancing human dialogue abilities, the range of services that humans can provide can be dramatically expanded. This project focuses on enhancing human dialogue abilities through virtual avatars.
