In human-computer interaction (HCI), measuring and understanding human intentions and communicating the state of the systems to humans are important techniques. Our laboratory studies technologies of a) artificial intelligence (AI) to understand human intentions using computer vision and sensory signals that make it easier to use various robots, b) medical support systems that increase the efficiency of medical care, c) VR/MR technology for teaching nursing communication, d) soft actuators that enables human-like touching, e) rescue robots and snake robots that can be used in disaster-stricken environments.
