Recently, there have been many studies on the activation of group communication, and it is important to easily and stably measure the states of group communication. We focus on group emotion expressed during conversation, and propose a method for estimating group emotion reliably using a Bayesian network based on both face image features and prosodic(More)
This paper describes a robotic agent that can promote communication when people first meet. When two people meet for the first time, a communication mediator can be important because people often feel stressed and cannot talk comfortably. Our agent reduces their stress by using embodied entrainment and thus promotes communication. In the research field of(More)
Cognitive dysfunction patients often interfere with cooking action and give up it. We have proposed the navigation system which supports cooking according to the grade of cognitive dysfunction, and have conducted the experiments of cognitive rehabilitation program (the cycle of cooking, eating, and reviewing) for verifying the hypothesis of having a(More)
This paper introduces a concept of cooking support system using networked robots and sensors. The system can recognize human activities in a kitchen and offer helpful instructions appropriately. It is based on the integration of embedded sensors and mobile robots, and can monitor cooking activities widely.
In this paper, we describe a method for extraction of mastication from image sequence. Mastication is the first step of eating and is very important. However, people do not need strong mastication muscle because the advancement of cooking and food processing technology makes soft foods. The weak mastication ability of recent human is about to become a(More)
This paper focuses on the preparation and consumption of meals-menu planning, grocery shopping, cooking, and consumption of people with higher brain dysfunction (HBD) as a novel approach to cognitive rehabilitation. A rehab scheme can be implemented using a cooking navigation system that supports menu planning that is tailored to the disability level of(More)
