PURPOSE:To provide a position sensor which can be fixed freely at any position without causing any detection error due to error in the fixing position. CONSTITUTION:A helmet 11 or a goggle 21 is fixed with accelerometers 13x, 13y, 13z having the X, Y and Z axes, respectively, as the input axes and also fixed with angular speed meters 14x, 14y, 14z having the X, Y and Z axes, respectively, as the input axes. Outputs from the accelerometers 13x, 13y, 13Z and the angular speed meters 14x, 14y, 14z are fed to an operating section 15 where the speed, position, attitude and direction of the movement of head part carrying the helmet 11 are detected through top-down operation. |
