The Study of Visual Cueing Effects on Attentional Guidance and Individual’s Response Prediction to Proposed Questions with Using Their Eye Movement Analysis

Abstract

In this study we examine whether it is possible or not to raise learning quality in less time with guiding eyes to target points ?And also whether adding visual cues have effects on prediction correctness of individual's responses to visual-auditory presented questions from analyzing their eye movements. We used electrooculographic signals from nine subjects to analyze individual's eye movements facing with visual- auditory stimuli. The stimuli include one spatial visualization test. The data were collected in an experimental procedure wherein subjects were trained how to solve the incoming problems and answering to the related questions. There were sixteen questions from the same category. A novel algorithm based on signal processing techniques was used to analyze EOG signals. After preprocessing using a band pass filter, 31 features were extracted from horizontal and vertical channel of EOG signals. Then 15 best features were selected using mRMR. Finally the selected features used for classification using SVM classifier. We used leave-one-person-out technique for classification to achieve more accurate results. Results from the experiment show a reduction in classification performance in with visual cues stage with respect to without visual cues stage also a reduction in
