Securing of reliability of testee data-Aiming at an objective measurement of Kansei information.

在以“感性信息是主观的”假设为出发点的感性信息研究中，基于心理感受评价的感性数据库构建是最有趣的工作之一。许多研究报告都包含被测试者对问卷的评价，例如，60名20多岁的学生。但在很多情况下，我们发现了问题，说“被测试者真的适合检查对象吗？”本课题提出利用呼吸、脉搏波、心电图等生理指标来提高感性信息的可靠性。人在感受诸如印象、快乐、悲伤和痛苦时，脊背感到发冷。而对于情绪刺激，则表现为脸色苍白、声音嘶哑、手抓汗。有一种批评认为，在主观性和情境依赖性较高的情况下，感性信息的客观性和可重复性保证是不可能的。然后，从“数据是主观的，测量和处理的技术是客观的”的观点出发，利用生理学数据来提高感性信息的可靠性是本研究的目的。从面部、声音、皮肤温度、呼吸等获得的生理指标的生理空间，整合了感性空间。即使人的“如何感受”是主观的，观察它的技术也要尽可能具有客观性。我们开发了以下主题，将生理学数据与感性信息联系起来。1)测量呼吸、脉搏波、心电图、皮肤电位反应时的精神紧张程度。2)手势通过红外和近红外相机成像并测量生理指标。3) fMRI对刺激浓度的测量

In the Kansei information research that had started by assumption "Kansei information is subjective", the Kansei data base construction based on the psychology feeling evaluation was one of the most interesting works. Many research reports contain the evaluation of the questionnaire by the testee, for example, of 60 students in his/her twenties. But in many cases, we found the problems, saying that "Was the testee really suitable for the inspection object?"In this project, we propose the utilization of physiology indices such as breath, pulse wave, and electrocardiogram, to improve the reliability of Kansei information. Man feels chilly at the backbone, when feelings such as impression, pleasure, sorrows, and pains are held. And for emotional stimulus, face turns pale, voice cracks, and hand grasps sweat.There was a criticism with an impossible assumption that guarantees of objectivity and reproducibility of Kansei information in the case that the subjectivity and the situation dependency were high. Then, it is the purpose of this research to improve the reliability of Kansei information by using the physiology data from the viewpoint "The technique for the measurement and processing should be objective though data is subjective". The physiology space obtained the physiology indices from the face, the voice, the temperature of the skin, and breath, etc., integrates the Kansei spaceEven if man's "How to feel it" is subjective, the technique for observing it is important of having objectivity as much as possible. We developed the following subjects for relate the physiology data with Kansei information. 1) Measurement of mental tension when effect of use of breath, pulse wave, electrocardiogram, and reaction of potential of skin. 2)Gesture by infrared rays and near-infrared rays camera image and measurements of physiology index. 3)Measurement of concentrated level to stimulation by fMRI
