Perception and emotion information processing


NTT Human Informatics Laboratories aim to clarify the relationship between each person's perception and emotion. We wish to moderate communication based on these perceptual and emotional characteristics. Our ultimate goal is to build relationships where individuals within the group respect each other as a group.

Specifically, we study the following two technologies.


  1. Emotional-perception-control technology
  2. Collaborative work support technology
