We investigate a novel type of interface that enables long-term vital sensing through noninvasive direct-contact vital sign detection and observation of body motion and feedback of health conditions through an illuminated display. Although various types of vital sign measuring equipment are currently commercially available, their complexity and inconvenient user interfaces coupled with human reluctance to continue long-term use discourage their daily use. Consequently, in this research we propose a method for involuntary measurement of vital signs of a user who is relaxing in a normal living environment. This study also investigates physical and physiological activity regarding body motion. In addition, a trend analysis is also performed with the help of past data automatically stored after each session.
