ABSTRACT:
A monitoring unit is mounted atop headgear fitted with a proportional level sensor which detects head inclination in the saggital plane. A battery powered microcontroller, interfaced with the level sensor, monitors the head tilt and provides a sonic indication whenever the tilt exceeds preset limits to the front or rear. The use of a proportional level sensor of the capacitive/fluid type enables the microcontroller to be configured to allow the user to preset different tilt limits, and to select different modes, for example beginning or advanced training, sitting, standing or exercising body positions, and to set up a designated training session duration, timed by sonic indication, during which the number and direction of head tilt deviations detected may be counted. Such statistical data may be displayed to the user on an LCD display. With the level sensor mounted directly to one side of the headgear, the monitor unit in a housing atop the headgear may specially non-rigidly attached to provide a degree of wobble or totter perceptible to the user as kinesthetic/proprioceptive feedback, in addition to the audible biological feedback received from the sonic tilt limit indication. The microcontroller system may be specially configured to recognize and ignore gross movements such as reaching or bending, while still feeding back to the user the finer postural deviations.
