Personalization of headphone spatialization based on the relative localization error in an auditory gaming interface

In binaural sound reproduction applications using head-related transfer functions (HRTFs) there it is beneficial that the properties of the HRTFs correspond to the personal characteristics of the real HRTFs of the user. In this paper we propose a method to choose HRTFs using a relative localization test. This allows to make the selection of the best HRTFs using a simple auditory interface. It is possible to design the HRTF personalization interface in a consumer device as an auditory game where the task of the user is to place sound objects in relation to each other. Two different interfaces are compared in a listening test. The results of the tests reported in the current paper are mixed and do not give a conclusive picture on the performance of the proposed system, however, they do give interesting insights about the properties of binaural listening.
