Mission critical and information overwhelming applications require careful design of the human computer interface. Typical applications include night vision or low visibility mission navigation, guidance through a hostile territory, and flight navigation and orientation. Additional channels of situation critical information can be better perceived using simultaneous audio and visual presentation. In this paper we present a multimodal simulation system as an open development environment for evaluation of sonification and visualization paradigms in augmented reality systems. The environment is implemented as a virtual audio-visual scene using the Java3D package, and used for performance measurements in tactical guidance applications. We present the results of a target tracking experiment with 10 participants using visual, acoustic and combined guidance. The experiment has shown that acoustic presentation significantly improve the quality of human-machine interaction and reduces errors during the guidance tasks.
