目前「建築資訊模型」 (Building Information Modeling，簡稱BIM) 大多應用於規劃及設計階段為主，若欲將其應用在施工及維護階段，則必須將BIM資訊於營建工程現地中呈現，而目前常見BIM軟體操作介面之設計主要以使用者能夠在電腦前面便利的操作使用為主，若須將其帶至現地使用，其便利性就會降低，其原因有兩點：1. 需要大量手動操作檢視模型與瀏覽資訊。2. 軟體畫面上的BIM模型與實際現地場景之間的資訊無法同步。故本研究欲利用「擴增實境」 (Augmented Reality，AR) 技術虛實整合的特性呈現BIM的資訊，將虛擬的模型、資訊與現地環境結合，透過「標識追蹤」(Marker-Based Tracking) 的方式使訊息可在同一畫面中同時呈現給使用者，以減少手動操作的步驟，並降低人機介面之複雜度。另因目前擴增實境技術於營建工程上之應用多以戶外環境為主，故本研究針對室內之環境進行開發應用，並結合室內定位技術，使系統在一定條件下辨識出使用者所在的房間，以獲取該房間對應之BIM元件資訊，也藉由室內定位技術使同一組擴增實境之Marker可設置在不同的房間而呈現出不同之訊息，以大幅減少Marker之使用量。
　　本研究針對系統方面進行效能上的測試與驗證，證明了這三項技術整合的可能性與可行性，並基於其原型系統，提出符合實用需求之應用情境，可應用於施工、驗收、營運維護及室內裝修等階段。透過使用者體驗測試及問卷之回饋，以驗證提出之系統與情境符合實用之需求，並可配合現有作業管理的流程及工具，增加視覺化的回饋來提升管理效益，以輔助現地之決策與判斷。

　　This study applied integrated indoor positioning and augmented reality (AR) technologies to develop an on-site viewing model of BIM. In the proposed model, BIM information is displayed and superimposed on real building elements in 3D component models or surrounding texts using AR technology. The building must have a wireless network environment inside, and each room uses the same set of markers to mark up the building elements in the room. The system uses wireless access points for indoor positioning to identify the user’s location in the room, and then uses markers to identify the building elements in the room. Once a building element is identified, the system retrieves the 3D model or property information from a Cloud-based BIM database and then superimposes them on a view of real building elements. A prototype system was developed based on the proposed model using the WorldViz Vizard platform. The proposed system achieved the integrated display of virtual BIM and real on-site scenes on a head-mounted display (HMD) without manual navigation for model viewing. Furthermore, four application scenarios were proposed to support operations in construction, acceptance, maintenance, and decoration phases of a project. The proposed system was tested to validate its performance and compare with traditional mode. The results indicate such on-site viewing model of BIM is functional and feasible.
