Applications of driver´s line of sight to automobiles-what can driver´s eye tell

We will first introduce the technical trend of recording line of sight from a distant point without any contact to the subject. In addition, automotive application concepts using a driver´s line of sight in a human-machine interface (HMI) will be proposed. With the progress of technology in optics and image processing, it is becoming possible to record a driver´s line of sight from a distant point without any contact. The movement of a driver´s line of sight while driving may have the potential to indicate a driver´s intention and his/her physical or mental conditions. Therefore, it is possible to apply a driver´s line of sight to the HMI systems such as the switching system using the driver´s fixation, the controller of the automotive equipment using the movement of the driver´s line of sight, or the sensor which detects the driver´s physical or mental conditions, which are closely related to the occurrence of traffic accidents. These systems using the movement of a driver´s line of sight may have potential to make automobiles safer and more convenient
