Creating an Audio Story with Interactive Binaural Rendering in Virtual Reality

Table 1

Qualitative data from the usability testing.

Sub ID	Headset	Remote	Button
1	It switches sounds but in an unknown way. It rotates your head around in the sound space	Intensity/volume of the sound	No understanding.
2	The sound moves with the direction that I am looking. It felt like I was able to explore different scenarios. Felt natural when looking around	Adjustment of intensity/focus of the sound	Seems like it saves the sound when you click it. Heard the sound for a longer period of time.
3	When I turn my head, it is like the sound moves with me. Sound becomes more clear depending on the direction. Much like in real life	Move left the sound becomes low and muffled. Move right sound becomes louder and clearer.	I did not feel much happen.
4	It is like normal audio navigation. Able to locate sound source according to head movement	Quite intuitive volume control.	A single sound continued playing. Like the other sounds stopped moving past me.
5	Sounds are passing by and I can follow them with my headset. Feel like naturally moving through sound	Did something to the intensity of the sound but not sure how it works.	I felt no difference.
