Construction Dashboard 互動式多系統工程資訊展示方法 Construction Dashboard 現今的建築物包含了各式各樣的系統，這些系統之間具有高度的相依性，進而導致工程人員難以了解工程資 訊間的關係並對系統進行協調。雖然目前很多研究試圖以4D及BIM等視覺化工具來解決工程上溝通問題，但 目前技術僅可提供資料查詢及顯示，無法更進一步的進行資料間的探索或比對，亦有可能造成使用者對資訊 的解讀發生困難或誤解其原有的涵意。 故本研究開發一互動式多系統工程資訊展示方法，以探索式視覺化的方式來幫助了解資料間的相依性，使用 者可以在資料間互相比對探索資訊，進而進行決策。此展示方法包含了四個資訊展示模組（時間、階層、關 係、空間）、四個資訊互動的方法（視覺化資訊探索、跨資訊強調、時間控制器和資訊提取）、及二個資訊 呈現方式（彈性資訊佈局和資訊展示矩陣），並實作了一名為Construction Dashboard的互動式多系統工 程資訊展示工具，以幫助工程人員能以視覺化的方式直接操作工程資訊，並即時得到視覺回饋的方式，來對 工程資訊進行探索，進而了解工程資訊間的相依性，並發現與解決工程上的問題。 本研究並透過使用式測試，驗證互動式多系統工程資訊展示方法之展示與互動方法能幫助使用者探索、了解 多系統資訊間的關係與其涵義，進而能夠更有效率的預測、解決和回答工程上相關的問題。

Construction Dashboard: a Framework of Information Visualization for Multi-System Construction
Modern buildings usually include multiple systems such as air-conditioning (AC), water supply and gas pipes, sanitary lines, telecommunication systems and security networks. Because these systems are highly inter-dependent, conventional methods for presenting information, typically a 4D model and a BIM model, are insufficient to effectively manage and coordinate various experts working on a project. This research proposes a framework that enables engineers to explore and interact with the information visually. It includes four information views (temporal, hierarchical, relational and spatial), four interaction functions (information exploration, cross-highlighting, time controller, and information extraction) and two display layouts (matrix hardware layout and flexible software layout). A prototype system called Construction Dashboard was implemented following this framework. To validate the effectiveness of the proposed framework we conducted a user test (N=30) using an example project involving four systems (power, AC, water and computer). Each user answered nine questions related to different management and coordination problems by employing both Construction Dashboard and the conventional method (3D model with a schedule). The results showed that the completion times, for each of the nine questions, to solve these questions are significantly faster when using Construction Dashboard. The success rates to obtain the correct answers are also significantly better in three of the nine questions.
