The present invention describes a method and system that is used to alert a person to the need to assume a correct backposition during sitting on a seat, using a sensor responsive to pressure, contact or presence of the person's back at a position relative to the seat that coincides with a correct backposture position of the person seating in the seat. Furthermore the method and the system are providing a signal consequent on the sensor sensing the absence of the person assuming a correct backposition and using the signal to alert the person to the need to assume a correct backposition; the alert can be sound or a visual display on a computer screen or the like or it can be using another means such as interruption of normal operation at a computer station. |
