Application of ecological interface design in a side collision avoidance system

ABSTRACT When changing lanes while driving, visual blind spots or improper driving behaviors can cause collisions. This study examined whether applying the concept of ecological interface design in a side collision avoidance system could effectively facilitate safe lane changing and provide drivers with early warnings to prevent or reduce the occurrence of accidents caused by visual blind spots. A total of 26 men and women aged 20–26 years were recruited as study participants and a driving simulator and eye tracker were used as experimental tools to collect relevant analysis data. The study results indicated that a side collision warning system with an ecological interface design not only did not distract drivers, but also assisted drivers in decision-making when changing lanes. Therefore, this new type of interface is recommended for employment as a vehicle safety device to prevent collisions caused by drivers during lane changes because of negligence or blind spots to achieve the objectives of preventing traffic accidents and enhancing traffic safety.
