Abstract
Abstract A system for unencumbered measurement of body posture or attitude utilizeson-encumbering force or proximity sensors to monitor an individual, where the individual need not be aware of the presence or action of the sensors. Outputs from these sensors are analyzed to infer body posture or attitude. In one embodiment, a set of sensors is attached to a chair, or other surroundings such as the floor, at locations where a person may be in contact with or in close proximity to one or more of the sensors or where movement of the chair could be detected. Each sensor has an output which provides a signal indicative of a response of the sensor to forces exerted by or motions of the individual. The outputs of the sensors are processed to estimate the body posture of the individual.
