Abstract
The human-machine interface test system enables the automated testing of vehicle interface systems and consumer electronics devices, replacing testing and validation that previously had required human interaction. The human-machine interface device (HMI test object or device under test) does not need to be altered (via hardware or software modifications or additions) to be able to be tested using the human-machine interface test system. The HMIts involves the automated audio input generation and output analysis, visual verification of a display screen with graphics and texts display, including touch and gesture interface control and feedback, external device interface, as well as data logging for communication between the HMI device and the rest of the system, that will replace the testing and validation that previously required human interaction. The HMIts provides more accurate and reliable results from the conducted tests, increasing repeatability and consistency in a controlled environment, while significantly decreasing test time.
