Physical, biological, and mental biomarkers of the human body can well describe its state. Body movement, heart rate variability, and the brain responses to various internal and external stimuli can reveal the symptoms and causes of many abnormalities in the state of human body. To differentiate these abnormalities and disease indicators, however, a variety of tests and measurements by means of suitable sensors need to be undertaken. These indicators can be quantified using data-processing and intelligent systems for better and quicker diagnosis of the abnormalities in humans. Although sensors and sensory networks have facilitated recording and quantification of many of the states indicating variables, there is still a long way to go to cover all factors involved in the full recognition of human body states.
