本研究針對僅採單一可見光相機的眼動儀,提出一套高效能、可即時運作的完整視線追蹤硬體系統。由於可見光環境下無法直接取得瞳孔或光斑,本系統改以內眼角作為穩定參考點,整合眼角偵測、眼球模型參數求解、幾何關係推算與動態縮放補償機制,建構完整的視線追蹤硬體架構。在既有高精度眼角偵測演算法的基礎上,我們將完整眼動儀系統硬體化,透過平行運算與管線化設計,在有 限現場可程式化邏輯閘陣列資源內實現快速的眼角定位與視線估測,有效解決使 用者頭部前後移動時的追蹤誤差問題。實驗結果顯示,眼角偵測模組在現場可程 式化邏輯閘陣列平台上的處理速度達每秒5,115幀,而完整的眼動儀系統整合後 仍能達到每秒476幀的處理效能,均具備即時運作能力。系統硬體資源使用率為 百分之十三邏輯元件與百分之三十五記憶體,證明本架構能為可見光眼動儀提供 可靠且高效的完整硬體解決方案。
