Résumé

We develop a device to guide blind people using binaural sound obtained by HRTF convolutions and reproduced by headphones. We have obtained good results in terms of user experience, but for guidance precision, the contribution of HRTFs compared to panning remained to be demonstrated. In this study, we design different binaural filters and we ask the subjects to orient themselves in the direction of a sound source. We compare their performances with two HRTFs and two panning filters, both for static and continuously moving sound sources. We show that HRTFs filtering allows the user to orient him/herself more precisely towards a sound source compared to a panning both in the static and the dynamic cases.
