Abstract
A light control device providing handsfree control of a lighting source using measures of the orientation of the lighting source is presented. The measurement of the orientation of the lighting source is monitored and while the orientation retains the light outputted by the lighting source within a designated area, the light output remains in an ON state. However, with the orientation of the lighting source indicates the light output may be outside the designated area, the light output is turned OFF. In addition, a method for calibrating the system to define the designated area is disclosed.
