A computer system and method for generating event distribution information using an audio file and controlling events corresponding to the user inputs based on the event distribution information. The golfer stands beside a golf ball while facing a target hole so that the ball is close to an exterior side of the golfer’s dominant foot. A sensing crankshaft angle is determined in relation to a reference position of the piston of the respective cylinder in order to detect the measuring signal according to a variable characterizing airfuel ratio in the respective cylinder, or an ambient pressure or a degree of opinion of a bypass valve of a bypass associated with a turbine in which the exhaust gas tract is arranged. When an obstacle is positioned on the optical path, the second IR signal is reflected to the IR reception circuit via the obstacle.
