建築物防火與避難是建築安全中的首要課題，目前避難的引導主要依據各類場所消防安全設備設置標準來設置相關避難標示，該標示在避難過程中所提供路徑搜尋的協助效能並不明確，因此有必要透過適當的學理方式來加以驗證，以確保該標示在避難時的功能，然而適度改善既有標示系統來提高避難上的協助亦值得加以探討。緣此，本研究透過虛擬實境方式解析既有標示與輔助標示A、B建構課題，所獲重要結論如下：
1. 依據受測者不同背景條件分析得知，無論何種標示系統其路徑搜尋所需時間依序均為：女性>一般民眾>專業者≒男性。
2. 若依不同標示型態區分時，則路徑搜尋所需時間：既有標示>輔助標示B>輔助標示A。另由節點選擇與樓梯選擇分析證實，輔助標示A效能顯著，所有受測者均未產生回頭或猶豫情境。
3. 性別造成路徑搜尋有所差異但並非每種情境均是如此，是否與空間規模大小有關則有待證實。
4. 居室到走廊每通過一次出入口(門)，須增加3~5秒避難時間。且在不熟悉空間中，居室內開門形式雖然符合使用概念但卻不利逃生。
5. 在可自由選擇左右轉時，門的可視性與空間條件將成為決定關鍵因子，且將造成不同於習慣左轉慣例。
綜觀前述，本研究建議應儘速擬定輔助標示設備專章，透過立法程序納入現有法令中，在輔助標示尚未建立前應加強教育宣導工作，其對象應以公共場所為主，以確保民眾避難安全。

Building fire prevention and evacuation is the primary topic for architectural safety. At present, emergency signs are installed mainly in conformity with the “Standard for Installation of Fire Safety Equipments Based on Use and Occupancy”. Nevertheless, the efficiency of emergency signs on way-finding is unclear. Hence, it is necessary to verify this issue based on academic theories to make sure that emergency signs are functional for emergency evacuation. It is also worthy to discuss how to make an adequate improvement in the existing signs in order to enhance their effectiveness. Consequently, the purpose of this study is to probe the functions of existing and auxiliary signs through virtual reality and the important research findings are as follows:

1. Analysis was made according to the different backgrounds of examinees. It is discovered that no matter what kinds of emergency sign systems, the order for the time needed in way-finding is: females>the general public>professionals≒males.
2. When a distinction was made among different types of emergency signs, the time needed in way-finding is: existing sign>auxiliary sign B>auxiliary sign A. Also, the analysis on node selection and stair selection proves that the efficiency of auxiliary sign A is obvious. None of the examinees turned back or hesitated.
3. Gender would cause some differences in way-finding, but it is not always the case under different kinds of circumstances. It still needs to be verified whether the size of space is relevant.
4. From the living room to the corridor, every time when one passed through the entrance (door), the evacuation time was increased 3~5 seconds. In an unfamiliar environment, although the door open style of the living room is conformity with the common-used concept, it is not good for evacuation.
5. When there is an option to turn the door knob to the left or right, the visibility of the door would become the critical factor and this would cause a left turn pattern which is different from the common practice.

Based on the aforementioned findings, this study suggests that a specific article concerning auxiliary sign equipment should be stipulated as soon as possible and included it in the existing laws and regulations through legislative process. Before the establishment of auxiliary signs, public education and promotion focusing on public space should be enhanced in order to assure that people can evacuate safely.
