本研究企圖再檢驗Block(2007)所提出呈現於螢幕視野的「開放空間感」。除了經由先前研究 (林大偉，2015)已檢驗的「形式因子」和「視野因子」之外，本研究提出Block未曾關注的「内容 因子」，並另外雇用不同的18位受測者，進行注意力實驗。據此，本研究將18位受測者所得，與 先前研究之18位受測者所得進行合併分析，共計36位受測者，藉此深入理解受測者在不同實驗條 件之下所採取的「注意力選擇策略」。結果顯示：（1)形式因子的二個水準之間具有顯著差異，因此 對於形成開放空間感具有潛在貢獻，其他二項因子則非；（2)受測者在動畫刺激的「搖晃鏡頭」情 境採取「分割注意」策略，可被視為最符合形成開放空間感的條件。

This study adopts the concept, “Open Space” proposed by Block (2007) as the starting point, attempting to re-examine the cause of it. Therefore, the strong visual movements and vision of large screens mentioned by Block, also the stories which this study focuses on are considered as 3 independent variables. Accordingly, this study merged the resulting obtained by measuring form 18 subjects in present study and other 18 subjects in previous study, totally 36 subjects are employed, and attempted to understand the “attention selection strategy” adopted by subjects under different experimental conditions. The result shows that, (1) there are significant differences between the two levels of the form factor, accordingly having potential contribution of forming the sense of open space while the other two factors do not. (2) Participants adopting the “divided attention” strategy in the scenario of random camera movement of animation stimulus can be considered as the most fitting term of forming the sense of open space.
