Comparison of Joystick guidance methods

Human factor represents one of the most common aircraft accident reasons. Therefore, an improvement of pilot-aircraft interaction by tactile feedback could be a way how to make flying safer. The goal of the research is to mediate aerodynamic characteristics of flow-field around the airplane to the pilot and to guide the pilot into avoiding dangerous regimes by the use of haptic feedback. Two guiding methods applied to a joystick are compared in order to improve the pilot-airplane interaction. Vibration motors and a sliding element were built in the joystick. Both methods are compared on two experimental tasks. Reaction time and accuracy of guidance are evaluated for both methods. The results are completed by the subjective opinion of the experiment participants.
