We aimed to develop a driving simulator that can be steered by neural signals without handling a steering wheel. It will be a pre-prototype of future vehicles utilizing human psychological and physiological information. We developed a driving simulator that uses steady-state visual evoked potentials (SSVEP) to control steering. First, we conducted a basic experiment to measure SSVEPs using two flickering checker patterns, which were located apart right and left and had different reversal frequencies. When observers looked at one of 7 positions between two checkers, observers' SSVEPs quantitatively changed depending on the distance between the fixation point and the left/right checkers. Then, we made a simple algorithm to calculate a steering angle from SSVEPs, and applied it to a driving simulator. Some naive drivers could steer a car only with SSVEPs along a curving course in real-time. However, there were large individual differences and instabilities of performance across different courses.
