由於目前市售的實景眼動儀價格都相當的昂貴，多數要動輒1萬塊美金以上，本研究期望能夠研發出一套低價的實景眼動儀系統，以較低的成本實現高精準度、高取樣頻率，並且整合分析軟體成為一套完整的系統。
本論文分成五個章節，第一章會介紹眼動儀的發展歷史、研究目的與方法；第二章介紹眼動儀的瞳孔追蹤方法與本論文實現系統所採用的方法、也會介紹到眼動儀數據分析的發展，最後則是整理出目前市售各大廠的實景眼動儀系統規格及特色介紹。
本論文的重點在於第三章，呈現實景眼動儀的實現過程與方法。我們提出創新的瞳孔追蹤方法，能夠濾除掉不必要的雜訊，使得瞳孔追蹤更加的準確，另外，本系統也改良了瞳孔映射於實際影像的方法，有效的提升了系統的精準度；本研究還整合了實驗室現有的眼動儀數據分析軟體，呈現了動態熱區圖與感興趣區域的數據分析。
論文的最後會以實驗來驗證本系統的效能，並且與各大廠做比較，其中我們在精準度(平均誤差0.43度)、取樣頻率(最高120Hz)與實景影像視角(水平視角120度、垂直視角98度)有著高出平均水準的表現。本研究完成了實景眼動儀的開發與分析軟體的整合成為了一套完整的系統。

The current scene eye tracker system costs approximately or more than $10 thousand dollars. In order to reduce the cost of purchase and the high usability rate of the scene eye tracker system, this research hope to develop a low-cost scene eye tracker system with higher accuracy and sampling rates. This research has also produced complete systems: (1) the integration of the scene eye tracker, and (2) the analysis software.
This dissertation is divided into five chapters. In Chapter 1, the background which comprises the history of eye trackers is introduced. In addition, the purpose of the research is stated. Research methodology is also map out in this chapter. Chapter 2 introduces the different theories and methods to be used for eye trackers and tracking pupil; the progressive development of data analysis; the scene eye tracker system specifications and features sold in the market.
The emphasis of this study is in Chapter 3 which demonstrates the implementation of process and methods of the scene eye tracker system. Tracking pupil to filter out the noise and improving the method of locating the pupil which is mapping to the scene image are the two innovative methods to enhance the system accuracy. This research also integrates its findings with existing laboratory analysis tool to show the dynamic hot zone and the data analysis of Region of Interest(ROI).
In Chapter 4 and 5, it concludes by providing evidence of effectiveness of functional scene eye tracker system through experiments, and compare to most of the scene eye trackers on market. The research findings of this paper have provided satisfactory results, particularly for the area of accuracy (0.43°), sampling rate (120Hz), and field of view (120° horizontal, 98° vertical). This research has also produced complete systems: (1) the integration of the scene eye tracker, and (2) the analysis software.
