Human-Computer Interface Design for Simulation of Activity-Travel Patterns
Time-space patterns of activity-travel are very complex, because the individual movement in time-space is a complex trajectory with many interacting dimensions. Potentially huge amounts of time-space data will be collected for different purposes by GPS receivers, and existing analytical tools in GIS may prove to be insufficient to handle these data. The purpose of this paper is to design a human-computer interface to model and visualize mobile objects with GPS data, in order to find an effective method to construct interactive manipulative 3D-GIS software of activity-travel patterns. The methods of 3D geographical data gathering and 3D map modeling are also present to support the analysis, display, and animation of time and space data. A prototype was implemented using the software of Multigen Creator and Vega to analyze GPS-recorded travel data in the city of Changchun, China. It allows the user to interact and explore the 3D map. Not only the visual properties of objects can be altered to reflect their various attributes, the highly flexible viewing and navigational environment is also a great help to the users.
