The invention relates inter alia to a method for operating a control unit (10) which enables input of actuating commands (B) for controlling a technical system, in particular a railway track system (20), wherein on a display unit (50) of the actuating device (10) the actual state of at least a portion (22) of the technical system is displayed and incoming actuating commands (B) from the actuating device for repositioning components of the technical system are processed. According to the invention, when an actuating command (B) arrives from the actuating device an eye-tracking device (60) ascertains whether before, during or after the input of the actuating command (B) the operator has looked or is looking on the display device (50) at the portion (22) of the technical system concerned by the actuating command (B), and the generation of a control signal (ST) for implementing the actuating command (B) at least also requires that the operator is looking at or has looked at said portion (22). |
