1. A method for safe visualization of safety-relevant information, the method comprising the steps of:

  • for all possible states of at least one variable input parameter, decomposing a safe visualization of the at least one variable input parameter into its safe base elements;

    for each of the safe base elements, enumerating and storing a set of all possible states of safe base element visualization;

    for each of the safe base elements, transmitting the set of all possible states of safe base element visualization to a target system that provides safe visualization at runtime;

    for each of the at least one variable input parameter inputting an actual state of the at least one variable input parameter into the target system and, for each of the at least one variable input parameter, determining a corresponding safe base element visualization corresponding to the actual state of the at least one variable input parameter and its correct state from the set of all possible states of safe base element visualization; and

    successively rendering and overlaying each of the corresponding safe base element visualizations on top of each other on a displaying means of the target system, thereby generating a safe visualization of the actual state of the at least one variable input parameter;

    whereby a safe visualization problem is approached as an additive representation that reduces states of visualization as compared to a multiplicative representation, thereby also reducing memory storage requirements and computing time to perform the safe visualization as compared to the multiplicative representation.
