Research Interest

Keywords: automatic assessment of human communication, multimodal interaction, communication support

Current theme: 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. 
Topic1: computer-aided communication supportOne solution to acquire better communication skills is social skills training (SST) which is a type of behavioral therapy. Since the number of therapist is not enough to provide SST for everybody who want to take it, we are developping automated SST system in TAPAS project. Specifically, I'm in charge of its automatic assessment of language and behavior, which is vital to provide appropriate feedback.
Topic2: automatic analysis of human communicationComparing physical disorders, investigating characteristics of psychiatric or developmental disorders is more difficult since we cannot directly see what is happening in their brain. To disentangle these complex symptoms caused by those disorders, I am working on their computational analysis based on machine learning techniques. Especially my current interest is in thought disorder, a group of symptoms observed across those disorders.
