When we use household When we use household appliances, we follow cues and appliances, we follow cues and constraint we sense from them constraint we sense from them without thinking. We, without thinking. We, consequently, decide our behavior based on consequently, decide our behavior based on information information obtained from the environment and the household obtained from the environment and the household appliances. Many of abilities that a human has acquired can not be appliances. Many of abilities that a human has acquired can not be explained even by himself/herself, though he/she is explained even by himself/herself, though he/she is able to use them; able to use them; e.g. ability to find something attractive, e.g. ability to find something attractive, sense of direction when sense of direction when walking in an unfamiliar area , and walking in an unfamiliar area , and proficient skill in manufacture. proficient skill in manufacture. These abilities are These abilities are accomplished by the affection rules and the accomplished by the affection rules and the cognitive cognitive mechanisms. If we understand them, we consequently are mechanisms. If we understand them, we consequently are able to make towns more livable and attractive and to design able to make towns more livable and attractive and to design machines that are safe, efficient, and comfortable for users.machines that are safe, efficient, and comfortable for users.Appealing point：The cognition and the affection are analyzed objectively based on experimental data. We propose new relationship between humans and environments or between users and machines. The cognition and the affection are analyzed objectively based on experimental data.

In particular, we focus on the following two points.computer (Fig. 1 right). In particular, we focus on the following (1) Development of biosignalmeasurement method and two points.(1) Development of biosignal measurement method and processing/analysis algorithms related to human cognition and processing/analysis algorithms related to human cognition and judgment. (e.g. estimation of an object that a person is paying judgment. (e.g. estimation of an object that a person is paying attention to or perceiving from multiple objects.) attention to or perceiving from multiple objects.) (2) Development of a quantification method for the human condition (2) Development of a quantification method for the human condition and touch, smell, taste, emotion that tend to rely on and touch, smell, taste, emotion that tend to rely on subjective subjective evaluation. (e.g. judgment of awake and drowsy states evaluation. (e.g. judgment of awake and drowsy states in Fig. 2.)in Fig. 2.)In biological measurement, we are working not only on measurement In biological measurement, we are working not only on but also on constructing a measurement environment and measurement but also on constructing a measurement environment and experimental design to obtain ideal results. We experimental design to obtain ideal results. We also introduce also introduce machine learning (deep learning, etc.) to extract machine learning (deep learning, etc.) to extract useful information useful information from signals and to interpret results easily.from signals and to interpret results easily.Special objectivesAppealing point： Our laboratory has accumulated know-how on biological signal Our laboratory has accumulated know-how on biological signal analysis through many years of research. We believe that it will lead analysis through many years of research. We believe that it will lead to commercialization of product by collaborating with companies to commercialization of product by collaborating with companies that develop measuring devices and embedded systems (Fig.3).that develop measuring devices and embedded systems(Fig.3).ContentSpecial objectivesWe study human-computer interaction and propose systems that are easy to learn, efficient in work, and comfortable to use.incorporation into systems / commercializationInteraction between human and environmentA human extracts valuable information out of surrounding situation, grasp meaning, and construct image or concept. The human’s behavior is induced by them. We analyze this interaction based on experimental data.Intellectual skillsIntellectual skill that is the kind of tacit knowledge and is difficult to explicitly transfer to another person. Cognition and affection play an important role in this skill.Illustrationawake state drowsy stateclosedeyes open eyesPerception, Cognition, Affection and Their Application to Human InterfacePerception, Cognition, Affection and Their Application to Human InterfaceProfessor Kohei NomotoProfessorKohei NomotoEvaluation of human cognition/judgment and quantification of human Evaluation of human cognition/judgment and quantification of human condition/emotion by analysis of biological signalscondition/emotion by analysis of biological signalsProfessor Tadanori Fukami Professor Tadanori Fukami
