Model mata yang dinyatakan melalui revolusi tentang paksi optik mata ialah salah satu model paling tepat untuk digunakan dalam kaedah anggaran pandangan 3D. Julat ukuran kaedah anggaran pandangan sebelumnya yang menggunakan dua kamera berdasarkan model mata dihadkan oleh dua sudut yang lebih besar antara pandangan dan paksi optik dua kamera. Kaedah sebelumnya tidak boleh mengira pandangan apabila melebihi had tertentu sudut putaran mata. Dalam makalah ini, kami menunjukkan ciri-ciri pantulan pada permukaan mata daripada dua sumber cahaya, apabila mata berputar. Kemudian, kami mencadangkan kaedah yang memanjangkan sudut putaran mata untuk anggaran pandangan 3D berdasarkan model ini. Kaedah yang dicadangkan menggunakan refleksi yang tidak digunakan dalam kaedah sebelumnya. Kami membangunkan sistem penjejakan pandangan percubaan untuk skrin projektor lebar dan secara eksperimen mengesahkan kaedah yang dicadangkan dengan 20 peserta. Hasilnya menunjukkan bahawa kaedah yang dicadangkan boleh mengukur pandangan lebih ramai orang dengan ketepatan yang lebih tinggi berbanding dengan kaedah sebelumnya.

Abstract: An eye model expressed by a revolution about the optical axis of the eye is one of the most accurate models for use in a 3D gaze estimation method. The measurement range of the previous gaze estimation method that uses two cameras based on the eye model is limited by the larger of the two angles between the gaze and the optical axes of two cameras. The previous method cannot calculate the gaze when exceeding a certain limit of the rotation angle of the eye. In this paper, we show the characteristics of reflections on the surface of the eye from two light sources, when the eye rotates. Then, we propose a method that extends the rotation angle of the eye for a 3D gaze estimation based on this model. The proposed method uses reflections that were not used in the previous method. We developed an experimental gaze tracking system for a wide projector screen and experimentally validated the proposed method with 20 participants. The result shows that the proposed method can measure the gaze of more number of people with increased accuracy compared with the previous method.
