System for unencumbered measurement and reporting of body posture
First Claim
1. A computer system for non-encumbered measurement of positional attitude of an individual, comprising:
- a non-encumbering device adapted to be used by said individual when operating said computer system;
a plurality of sensors associated with said device, each sensor having an output which provides a signal indicative of a response of the sensor to the individual using said device;
means for estimating a positional attitude of the individual relating to said device from the signals output by said plurality of sensors; and
,means for displaying an animated image of the individual on said computer display in a positional attitude which mimics the estimated positional attitude of the individual.

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.
