An Eyemovements Study On Features Of Processing For Three-dimentiongal Figure

Three-dimensional figure is a special figure which is made by binocular disparity, and the recognition of three-dimensional figure has close relationship with stereo vision. It is an active cognitive processing to recognize the three-dimensional figure, which concentrately incarnates on the strategies of processing. The research uses eyetracker to note the index of eyemovements when the subjects look at the three-dimensional figure, and then we discuss the features of the processing. The subjects are filtrated from LiaoNing Normal University,and the materials are three-dimentional figures which are dealed by Photoshop11.0. The research contains two preparative experiments which are the selections of subjects and materials and two formal experiments. Experiment One is one factor between subject design, which uses naming task to note the index of eyemovements for different kinds of subject(scan recognize the three -dimensional figure/can not recognize the three-dimensional figure), and then it analyses the differences between different kinds of subjects. It discusses the the processing strategies of subjects who can recognize the three-dimensional figure. Experiment Two is 2(display fashion:erected vs inverted)×2 (display condition:clear vs blurry)two factors within subjects design,which uses naming task to verify eyemovemental features of subjects who can recognize three-dimensional figure under different recognitional difficulties. Now, we define the subjects who can recognize three-dimensional figure as A-subjects, while the subjects who can not recognize three-dimensional figure as B-subjects. Getting the following conclusions:1.The index of the B-subjetcs are observably more than the A-subjects, such as reacting time, total fixation duration, number of fixations, number of gazepoints.2.The fixation frequency of the A-subjetcs and saccade are going to be observable with the B-subjects'.3.Different display fashions and conditions don't influence the A-subjects'performance of recognition, such as the reacting time and veracity.4.Under the inverted display fashion, the A-subjects can use the method of shorter total fixation duration and more number of fixations to recognize the content of the figure.5.Under the blurry display condition, the A-subjects use more average fixation duration, shorter saccade to finish the recognizing task.
