6.2. 未來展望
在未來，我們希望能有下面幾點的改進：
攝影機架置參數的維度：在搜尋演算法中，我們假設 3D 環境不會過於複雜，
使攝影機不用嚴謹考量架置的高度，故我們省略了 3D 空間中 Y 軸的維度，使搜 尋在 2D 平面上進行，得出 2D 位置後，再加上平均高度。但是在環境複雜或者 空間龐大的環境當中，我們的方法便不能得到最理想的效果。我們希望將來能加 入有效率的搜尋演算法，如 Lazy PRM[20]，以解決於 3D 環境中的搜尋結果的效 能耗費。
互動故事劇本：現在我們的故事劇情，由事件節點組成較為簡單的 Graph 狀 結構，在未來我們希望能豐富故事的發展模式與使用者的互動模式，讓故事的發 展不只是按照選擇題來決定走向，也讓使用者能夠因為豐富的互動模式而感受到 更多的參與感。
故事結構的應用：在我們的腳本中，針對功能項我們只有設計 Tension 跟 Might 這兩項數值，但對於故事的情境，或者可以用更高階的參數來描述。往後 希望能設計出較為抽象的階層關係模型，參考[15]的概念，利用 Propp 歸納的故 事宏觀情節架構，讓系統能夠自動地按照目前環境的狀態來判斷情境，再設計更 貼切的情境參數來描述情境，進行情境與攝影模組的對應，減少在腳本中對每項 事件詳細描述其情境的累贅工作。
豐富平台內容：現在的 IMStory 系統中，只有提供三個基本的角色動作供劇 本撰寫使用，往後希望能加入更多的動作資料來豐富劇情。在場景方面，亦希望 能提高貼圖與燈光的視覺效果。
