Spatial Audio Selection via Intensity-Based Directional Prioritization

The patent applies local quality by assigning different intensity levels to different audio tracks based on their spatial direction. The primary audio track from the front direction is provided at higher intensity, while secondary tracks from other directions are provided at lower intensities. This creates a non-uniform intensity distribution that helps users naturally prioritize the front audio source while remaining aware of other directions, resolving the contradiction between comprehensive awareness and effective prioritization.

The patent inverts the traditional angular selection approach by using intensity-based spatial audio presentation. Instead of requiring users to actively select directions, the system automatically presents audio tracks with varying intensities corresponding to their directional sources. Users can passively perceive and prioritize audio from different directions through intensity cues, and can easily switch between tracks by simple input actions, making the interface more adaptable to natural user preferences.

The patent applies dynamics by making the audio track assignment flexible and changeable based on user input. While the default configuration presents the primary track from the front direction, the system dynamically allows users to switch between different audio tracks from various directions through simple input actions. This dynamic capability enables easy transitions between front and side audio sources without complicating the overall interface, resolving the contradiction between simplicity and flexibility.
