Design and implementation of interaction mode for system test based on wireless PDA

In special vehicle function test, vehicle operator and test operator must work together in an interactive way. The traditional interactive approach includes command, gesture, interphone, etc, which carries little information and can be disturbed by noise or environment. This paper proposes a kind of interactive mode based on wireless PDA, which adopts PDA as the display and input terminal. The testing host computer communicate with PDA via wireless approach, which can send text, image, speech or other information to PDA while the PDA can show operation hint, image, and also send back operation result and data to the host computer. This interactive mode provides a good approach for information transfer, and enrich the content of interactive message, which in turn can improve testing speed and test efficiency.
