Effects of Image Features and Task Complexity on Eye Movement while searching Metro Map routes

In order to improve the readability of metro maps, reading behavior for route search has been analyzed using eye movements in the previous studies. The factors of the numbers of route and transfers on the route were examined. Since the metro map images are different between cities, effectiveness of another factor for image features on eye movements was examined using features of saliency maps. The 48 metro maps were classified into three clusters, the difference of feature of eye movements was extracted. As the results, relationship between fixation time and values of the saliency was discussed.
