I work at a hospital where Vocera badges are used in the same manner. Those badges aren’t directional audio and I’m sure PHI is being shared without consent, well, at least being over heard. This patent by apple has me thinking better is coming in this space! Yes!
What would be significant in introducing such a function? If my head is turned to the right will I hear more drums and to the left more guitar? I seem to be missing the point of the reason to even take into account the person’s head movements when listening to Apple Music.
