This research introduces Semantic Audio-Visual Navigation in Continuous Environments (SAVN-CE), a realistic task where agents navigate freely towards intermittently sounding targets in 3D spaces with dynamic audio rendering. The proposed MAGNet model, leveraging multimodal memory and self-motion cues, achieves superior navigation success by maintaining goal awareness even when auditory signals are absent.
Key insights
- Dynamically rendered binaural audio and continuous movement substantially enhance the realism and complexity of embodied navigation tasks compared to discrete, precomputed methods.
- Effective integration of historical context via memory and explicit self-motion cues is crucial for maintaining goal awareness and improving navigation success when direct auditory signals are intermittent or lost.
- The ability to accurately estimate sound source localization and activity, even during silent periods, directly correlates with and enables more robust navigation performance.
