Fixation identification for low sample rate mobile eye trackers
This paper presents a novel method of fixation identification for mobile eye trackers. The most significant benefit of our method over the state of the art is that it achieves high accuracy for low sample rate devices worn during locomotion. This in turn delivers higher quality datasets for further use in human behaviour research, robotics and the development of guidance aids for the visually impaired. The proposed method employs temporal characteristics of the eye positions combined with statistical visual features extracted using a deep convolutional neural network, inspired by models of the primate visual system, through the fovea and peripheral areas around the eye positions. The results show that the proposed method outperforms existing methods by up to 16 in terms of classification accuracy.
