Panasonic has been developing digital human technologies which visualizes people's mental and physical state. Applying know-how from usability evaluations and sensing technologies gained through products developed over the years, the system can take images captured from the camera and analyze and quantify the physical stress and detect changes in a person's mental state, for example their level of relaxation. The analysis and evaluation solutions can be used for various applications including yoga lessons, drowsiness detection while driving, and sports image analysis.
