摘要: | 景觀評估中景觀偏好被視為評估一種依據,而在景觀偏好的相關研究中,Kaplan & Kaplan(1989)提出的偏好矩陣為最常被提及的理論,而神秘感是偏好矩陣中的的預測因子之一。在神祕感被提出時,定義中雖然有提及對於方向性指引的需求,但並沒有針對其來源、影響做出相關說明。因此,過往神秘感的相關研究中,皆透過採用平面媒體做為刺激物,進而指定受測者的觀看方向。然而,在平面媒體上,並無法針對方向性因子進行控制,因此在缺乏其他有效測量神秘感工具的情況下,有關方向性對於神祕感的影響始終沒有研究與定論。 沈浸式虛擬實境(Immersive Virtual Reality, IVR)技術,隨著科技進步逐漸成熟與普及,同時被認為可以讓使用者在虛擬環境中,產生與在真實環境中相同的反應;但是對於IVR是否能成為另一種有效測量環境神秘感的工具,目前並沒有相關研究針對此議題進行探討。因此,本研究共分為三個研究,所有研究皆以實驗法進行,首先透過研究一,利用IVR與照片評估法呈現相同環境,確認使用IVR評估環境神秘的效果;再經由研究二,使用IVR作為實驗工具,比較不同觀看模式之間差異,補足過往神秘感研究對於方向性影響的不確定性;最後藉著研究三,同樣使用IVR作為研究工具,將環境依照方向與神祕程度進行組合,比較不同環境間神秘感之差異,釐清方向性與神祕感變化的組合如何影響環境神秘感評估。 在研究一中,配對檢定結果顯示,IVR評估法與照片評估法,在環境神秘感與空間臨場感上,前者評值顯著高於後者;在相關性的部分,IVR評估法與照片評估法,在環境神秘感與空間臨場感變項上,兩者之間的評值具有顯著的高度相關;由此可知,受測者在每個場景中的評分變動趨勢相同,同時具有顯著差異。說明IVR可作為除傳統照片評估法以外,另一種有效評估環境神秘感的研究工具。 研究二經由配對檢定結果顯示,在指定觀看方向與不限觀看方向兩種觀看模式下,進行環境神秘感評估,兩者之評值並無實質上的差異,表示即使觀景者在全景的狀況觀看景觀,觀景者依然會以特定方向之景觀作為神祕感的評估依據,因此可確認方向性會影響神秘感評估。。 研究三結果說明當起始觀看方向不同,對於整體環境神秘感評估具有顯著的影響。不同環境方向中神秘感變化組合,各組之間在環境神秘感評估上有顯著差異:前景為高神秘環境,將不受到後方環境神秘感的影響;前景為低神秘環境,整體環境神祕感評值,與後方環境神秘感變化具有正向關係。 本研究以三個子研究證明,IVR可做為新的測量環境神秘感的工具;進行神秘感評估時,受測者本身就會指定評估方向;以及方向性與不同神秘感組合,將會影響環境神秘感的評估。因此未來在評估環境神秘感,可使用IVR替代傳統照片評估工具,提供更精準的實驗控制以及豐富且準確的空間資訊。而過往研究中所採用的刺激物,可能並不能完全代表在真實環境所感受的神秘感,必須要做進一步的檢視;同時,在進行環境設計時,可透過控制觀看方向性,使觀察者在相同環境中,感受到環境神秘感的變化,豐富環境體驗的經驗。 Mystery was one of four informational variables included by Kaplan & Kaplan (1989) in their well- known “preference matrix.” Mystery offers the promise of learning more about an environment as one moves further into it. Which means when someone needs to enter the environment, the need to get information about directionality arises to know where to go. However, no empirical evidence had shown if the directionality of viewing behavior would influence perception of mystery. A possible reason is the difficulty of manipulating direction of viewing behavior both in 2D photo simulations and on-site experiences. Immersive Virtual Reality (IVR) has become a popular research equipment which allows subjects to integrate into virtual environments that simulate real-world situations. However, it remains doubtful if IVR can be another tool for measuring mystery, since its ability to identify the level of mystery in the environment has not been tested empirically. For the issues aforementioned, this thesis consisted of three major parts. The first part tested the ability of IVR technique for identify the level of mystery in the environment. The second part intend to prove the influence of directionality of viewing behavior on perception of mystery using IVR technique. The purpose of the third study to explore the both the directionality in viewing behavior and changes in the level of environmental mystery on perception of mystery. In the first study, pairwise comparisons showed that photographic and IVR ratings differed significantly in preference, mystique, and spatial presence. All paired evaluations in the experiments were significantly correlated, indicating similar trends across methods. Therefore, IVR technology can measure the level of mystery in an environment as accurately as a photo. In other words, IVR will be another tool for measuring mystery. The second study focused on the influence of directionality of viewing behavior on perception of mystery. The results showed that no matter the media provide information about directionality or not. Subject will use the environment ahead as a basis for perceiving mystery. That is to say, directionality of viewing behavior will influence perception of mystery. The results of the third study revealed that subjects’ evaluation was different when same environment was viewed from in front or behind the subjects. Put simply, the environment mystery was influenced by the mystery level of where you start to view. Results also showed the change mystery's level of behind environment would not influence people measure mystery, when the in front environment reached a high mystery level. Furthermore, the study also found objects’ mystery evaluation were positively related to the mystery's level of behind environment when in front environment has a low mystery setting. The results from the above three studies confirmed IVR technique could be a valid tool in measuring mystery. In the same time, this study also proved that one’s evaluation of mystery would be influenced by the directionality in viewing behavior. Therefore, IVR could serve as an ideal research tool in landscape studies which could providing sufficient study controls. Additionally, all the results could contribute to the future design and planning tasks. |
