Traffic Safety Oriented and User Centered Human Machine Interface Design of In-vehicle Information System

The need of in-vehicle information system was analyzed. The paper summarizes principles, existent design standards and guidelines for human machine interface of in-vehicle information system. We comply with traffic safety-oriented and user-centered design concepts. Basing on existent design standards and guidelines, we design human machine interface of in-vehicle information system. Design contents consist of visual display, auditory display, and input control. From the perspective of traffic safety, we should relieve interruption of driving task as possible as we can. Meanwhile, we should complete the interaction with in-vehicle information system. The total design principle is to keep the drivers´ two hands on the steering wheel, and minimize the interaction time of visual manipulation, auditory manipulation. Different drivers have different physiology-psychology characteristic, so design requires human factors engineering knowledge.
