Calculating cognitive efficiency score for navigational interfaces based on eye tracking data |
摘要 |
A method and apparatus for computing efficiency score of a page is provided and using the efficiency score to optimize page design. Eye tracking study is performed on a group of subjects where eye fixation data, gaze plot data, and qualitative information data are collected. Fixation information data for page is aggregated over the subjects in the study. The fixation information data is divided into a grid. Number of fixations is computed for every grid element. Seen and noticed thresholds are established for every grid element. Seen and noticed area of a page is computed by counting number of grid elements falling into either threshold. Ratio of area noticed over area seen is computed to yield efficiency score. Page fixation data are compared for alternate page designs. Areas of large difference are correlated with gaze plots and qualitative data to identify distinguishing features. |
