Gaze measurement to evaluate safety in using vehicle navigation systems

It becomes popular to use smart phones as a car navigation system. Conventional navigation systems were already designed following the published guidelines to ensure driving safety; however, guidelines for the smart phone navigation system are still undeveloped. To assess the safety of these devices, the car navigation systems are integrated into a driving simulator. The experiments are carried out by changing the size and the position of the display. Gazing points of the drivers are measured when they are driving on the driving simulator following the instruction of the car navigation systems as well as obtaining questionnaires. The results indicate the frequency of eye movement increases when the display is installed close to the driver's eye, while total time gazing the display does not change significantly in all the conditions.
