운전자 부하 분석에 따른 차량내 디스플레이 장치 디자인 가이드라인 개발

In recent years, the roles of in-vehicle display systems have been significantly increased due to the increased demand of display information from car-IT fusion products such as multimedia, car navigation, ASV, telematics and many others. There is one key factor when designing the in-vehicle display that are to minimize the driver workload and to optimize the interface efficiency. In this research, the evaluation method for measuring the driver workload is investigated. The evaluation process includes, DOE, Secondary task (reaction time and correct rate) and bio-signal analyzing. One set of experiment with more than 18 persons have been conducted with several display designs while the driver is analyzed. Experiment results have been used to develop the design guideline to minimize the driver workload and to optimize the screen design.
