Abstract: Based on self-developed operation simulation and performance test system of vehicle-mounteddisplay and control terminal, the influences of input modes, i.e., touch and mouse, on crew's information processing capability are analyzed by taking task completion time and error rate as evaluation indicators. The results show that the influences of different input modes on crew's information processing could be effectively discriminated by using the proposed method, and the touch mode should be regarded as the test mode of real operation performance test. However, the training effects of two input modes on mastering system operation functions are the same. The results can provide reference for the input mode selection of vehicle-mounted display and control terminal and the training of armored vehicle crews.

Key words: ordnance science and technology, vehicle-mounted display and control terminal, input mode, information processing capability
