What is it about?
We designed metaphoric sounds that can communicate any location in continuous two-dimensional space. The sounds are unambiguous and allow for blind navigation, guided by sound only.

Why is it important?
In many surgical interventions, visible orientation cues are rare, e.g., because they lie below the skin. Here, image-guidance assist clinicians to find legions, needle insertion points, or cutting trajectories. But both the demand in graphical processing and the mental operations to interpret the visual data are very high. Audio processing and sound interpretation on the other hand may be less demanding to interpret. But a premise is that independent spatial dimensions are represented (sonified) by independent characteristics of sound.
Perspectives
The psychoacoustic sonification enables navigation in scenarios that are overly visual, like surgeries, driving and piloting. But the approach is not restricted to navigation. Many kinds of multi-dimensional data can be unambiguously sonified with our approach.
