Research On The Eye Analysis Techniques Used In The Visual Quality Evaluation Of Landscape

Visual quality evaluation of landscape is the premise for developing and utilizing the tourist resources. Every means of evaluation has its own unique advantage, but still leaves much to be desired.This paper attempts to introduce the eye analysis techniques of experimental psychology into the visual quality evaluation of landscape, takes the object of study by the landscape of Danxia landform in Sunan, Gansu. The author analyses the eye movement data and the subjective evaluation score of the "participants" to the single pictures and the AOI of the pictures in different types of landscape, and tries to probe the feasibility of eye analysis techniques used in the visual quality evaluation of landscape.The bad influence which may be caused by the different picture could be neglected through analysis first. From the analysis to the eye movement data and the subjective evaluation score of the "participants" to the single pictures and the AOI of the pictures in different types of landscape,we can see that: For the single picture, the fixation frequency, fixation duration average and fixation proportion almost share the same change trend with the subjective evaluation score, that is, the higher of the subjective evaluation score, the bigger the fixation frequency, the longer the fixation duration, the bigger the fixation proportion. And for the AOI of the pictures, we also can see that "score according to the proportion of the fixation time", "score according to the first fixation duration" and "fixation frequency" share the same change trend with the subjective evaluation score when the participants watch the AOI in pictures, that is, the higher of the subjective evaluation score, the bigger the proportion of the fixation time, the longer the first fixation duration, the bigger the fixation frequency. So the process of fixation in eye movement is well correlated with the subjective evaluation score. The author also confirms this conclusion through the factor analysis and stepwise regression analysis of the Multi-component linear regression analysis, and gets some regression model, and then puts forward the evaluation process model based on the eye movement. So it is feasible to use the eye analysis techniques in the visual quality evaluation of landscape.What's more, the participants in different gender have the different eye movement characteristic. The women watch more carefully and acquire more picture information, but the men pay more efforts and have the larger range than women. Different genders have different preferences to different types of landscape. We can see that men and women are both very interested in landscape of color hilly, but have little interest in landscape of canyon. There are little differences of interest between landscape of ice ditch and landscape of window pattern landform. Women have more interests in landscape of ice ditch, but men have more interests in landscape of window pattern landform. The author puts forward some opinions and suggestions for its development based on the different types of landscape features at last.
