參與式建築資訊模型檢討之虛擬實境式溝通平台

Abstract

成功的參與式建築資訊模型檢討，是能讓最終的建築設計滿足終端使用者的需求，為此需要一個有效的溝通平台，來讓即使是沒有相關設計規範知識，或是並不在同一空間下的終端使用者，仍然可以透過該溝通平台，來找到設計的問題點，並共同協商新的設計方案。為了達到這樣的目的，本研究提出一個虛擬實境式溝通平台命名為Virtual BIM Reviewer (VBR)，其是以建築資訊模型為基礎，並輔以虛擬實境技術來進行開發，以視覺化建築設計方案的方式，達到理解設計跟促進溝通的效果。為了驗證VBR的有效性，本研究設計了一個客戶變更設計的情境測試，讓參與者在一模型中進行問題尋找與方案協商；所有的參與者都是擔任終端使用者。實驗結果顯示，在問題尋找的工作表現上，VBR組顯著的比常規BIM-based組的表現好；在方案協商的工作負荷上，VBR組顯著的比常規BIM-based組的負荷低。總結來說，VBR是一個可以支持參與式建築資訊模型檢討的有效溝通平台，而它亦可以再透過不同的使用者情境測試來優化改善，像是在溝通討論中同時有不同類型的參與者，以及參與者們進行非同步的溝通討論。

A successful participatory BIM model review makes the design appropriately satisfy the demands of end-users. It requires an effective communication platform that allows end-users to identify design issues and to negotiate design solutions even though they have a limited knowledge of design specifications and/or they are geographically dispersed. Therefore, this research proposed a Virtual Reality (VR) enhanced communication platform namely Virtual BIM Reviewer (VBR). The VBR used a BIM model as a basis and assisted with VR technology to visualize and comprehend designs and to facilitate communications. A user design change scenario was designed to evaluate the effectiveness of the VBR by comparing it with a conventional BIM-based reviewer. In the experiment, the participants were asked to identify design issues and to negotiate design solutions; the roles of all participants were end-users. The results showed that the average issue they found through the VBR is significantly higher than through the BIM-based reviewer. The average task loading for solution negotiation they suffered through the VBR is significantly lower than the BIM-based reviewer. To sum up, the VBR is an effective communication platform to support a participatory BIM model review and it can be improved under different user scenarios such as communication including different types of participants and non-simultaneous communication.
