The training apparatus uses a number of disc readers (2 - 8) to provide video output signals which may be used to depict apparent motion along a basic route. A video switch (11) is controlled by a processor (10) to select the video signal to be displayed. By running the disc readers (2 - 8) in synchronism with each other the output signal selected reflects changes in the selected route which would be caused by (e.g.) a vehicle driver varying the position of a steering wheel. A chroma-key switch (15) is used to superimpose images generated by the processor (10) in the background picture to simulate (e.g.) changes in light signals, parked vehicles and the like. |
