Re: distance perception in virtual environment


Distance perception in a virtual environment is one topic in the JASA article by Hartmann and Wittenberg, vol 99, 3678-3688 (1996).

It shows that systematic errors in the synthesis bring the image closer to the head, and ultimately inside the head.

Dear list,

I am now wondering how to subjectively evaluate distance perception in virtual environments which might be synthesized using WFS or HOA (high-order ambisonics). In my experiments, the sounds were synthesized at different distances and presented to listeners for distance discrimination. However, the listener cannot easily perceive the difference in distance between these sounds.

Anyone can share some ideas or experiences in distance perception experiments? or share some references on this issue?

Thank you so much.

Best regards,
