Measuring Human Response to a Visual Stimulus Using a Joystick

Measuring the human response to a visual stimulus is the next necessary step for future flight simulator testing. Two different methods: an identification algorithm, designed by the authors; and a simulation system MATLAB add on System Identification Toolbox, were used. The results from both methods, i.e. the individual parameters of the transfer function for the pilot behaviour model, were practically identical. This proved that both methods are credible and fully suitable for this type of input and output data. Individual time constants represent the joystick movement that is dependent on the current psychological and physical state of the tested person. Using time constants is the easiest way to read Transport delay, without any mathematical functions, and to see the difference between a person with fast and slow reflexes. Having such mathematical formulas for analysing the measured input and output data ready, these methods can be used in the future to analyse the acquired data from flight simulators.
