A Study of Driver’s Maneuver Characteristics Using the Joy-Stick Device

An aspect of recent human interface concerns suitable and comfortable maneuvering system for drivers. An operation device with a Joy-stick was developed, that was compared with a conventional steering wheel by actual vehicle traveling tests. The vehicle’s motion under slalom travel conditions was filmed by VTR (Video Tape Recorder) cameras and was analyzed using the image processing system. Driver’s heart rate was also measured to examine his mental load while maneuver. An optimum steer angle with respect to an angle of inclination of the Joy-stick by driver’s manipulation was examined using the driving simulator.
