A Multi-User Mobile System to Visualize Environmental Processes
Abstract:

This paper presents a multi-user mobile system to visualize environmental processes. Two main modules define the system’s architecture, a geo-referenced model and an Augmented Reality (AR) composition module. The geo-referenced model is applied to the visualization of water quality, in rivers or lakes, but other models can be used allowing the visualization of different environmental processes. The AR composition module is the client side of this architecture, allowing users to visualize and interact with the geo-referenced model via two different views. The first view, a 2D computer animation, enables the interaction with the geo-referenced model by adding or removing pollutant agents to the simulation. The second view, AR view, enables users to visualize the simulation over real images. Thus, it is possible to observe the evolution of the model in the vicinity of the users, superimposed over the view of the real environment.
