Abstract: A method for comparing effects of equipment on a user's head mobility, which includes attaching a camera and a laser pointer on a user's head, the camera capturing the laser point and the trace of the laser pointer against a spatial reference, adjusting the laser pointer such that the laser pointer points outwardly in the direction of the line of sight of the user, configuring a work area such that the work area is constant, placing the user wearing the equipment the camera, and the laser pointer in the work area, scanning the full range of motion of the user wearing the equipment while recording the trace of the laser pointer via the camera, repeating the above listed acts with a different equipment configuration, and comparing and reviewing the recordings of the trace of the laser pointer for the equipment configurations to compare each configuration's effects on head mobility.
