4D軟體近年來不論在學術研究上或者業界使用上皆公認4D軟體擁有改善團隊溝通能力、預先防範空間與時間衝突以及增加生產力的優點。當4D軟體要在工地現場展示與使用時，因受限於工地環境複雜且工作地點變動較大，一般使用上以輕巧方便攜帶的手持式裝置如PDA作為工地現場4D軟體的載具，但是在手持式裝置上使用4D軟體必須克服兩個難題，一是手持式裝置的處理效能以及記憶大小的限制，二為手持式裝置一般使用按鍵與觸控筆當作操作介面，這樣的操作介面並非是為了瀏覽虛擬空間而設計，要將它拿來操控視覺化模型並不合適。
為了改善上述手持式裝置操作介面不太適合用於瀏覽虛擬空間，本研究建立一套能夠應用於手持式裝置上，並且結合多點觸碰姿勢與動作偵測於4D模型瀏覽的操作介面雛型。並透過使用者測試來驗證此多點觸碰姿勢結合動作偵測的操作的方式，比起傳統觸控筆式的操作方式更為方便，且亦能符合工程使用上的需求。

4D CAD has been found having the capabilities to improve the communication between project team and property owner, prevent the spatial and time conflict, and promote the productivity. It is often inconvenient to carry bulky plans and reference documents into the field. And Handheld computers seem to have the potential to solve this problem. But when applying 4D CAD on handheld computers like PDA, there are two problems must be overcome. One is that the limitation of processing power and the size of the memory of a handheld computer. The other is that the input device of a handheld computer is not suitable for navigating in a virtual environment.
In this research we develop a multi-touch gesture prototype for 4D model viewing on a handheld device. We carry out a user tests to validate whether the developed gestures are more intuitive for users to manipulate 4D model on handheld devices in a construction site.
