Abstract
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.n 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.
