The identification of present indicators and controls were tested in several series with 100 subjects having varied demographic backgrounds and their statements evaluated as to the individual technical functions. In tests with another 50 persons, we measured the learning effects as functions of both the individual labels and the various demographic groups. Evaluation of these test series shows the influence of the different demographic data among the persons tested. With 150 subjects tested in European cars the driver's expectations as to where a specific control is located and what specific manipulation he associates with this control was investigated.
