Keywords: automatic assessment of human communication, multimodal interaction, communication support
Current theme: automatic generation of nonverbal behavior
Nonverbal behaviors are pretty crucial in human communication, making it natural and usable for human interlocutors. However, current automatic gestures on virtual agents have the following limitations: generation quality, generation time, semantic alignment with verbal contents, and reciprocal interaction with others. Although image generation models evolve rapidly, gesture generation models can be applicable to control real-world robot behaviors as well; therefore, they are more generic approaches.
Past theme 1: automatic assessment of human language and behavior
To communicate with people, we use languages, body gestures, and facial expressions. Although it is crucial to live in human society, we have to learn through daily lives. However, even for adult people, communication can be difficult and annoying. Especially, communication in working place or school is troublesome.
