| Outline of Final Research Achievements |
Vital information is representative and important information in the unconscious computing environment, in which information is sensed and recorded without users' attention. In this project, sensing and signal processing techniques are developed for enabling accurate data acquisition through an electric field sensor or through a camera. An electric field sensor has been developed that senses pulse wave as the change of the position or the shape of nearby conductor. A signal processing flow that accurately extracts heart rate from the measured pulse wave, which is contaminated with motion artifacts, is developed. In addition, heart rate interval that is useful to estimate disease or stress condition, is estimated from video images.
