Authentic 3D audio is a critical factor for a truly immersive virtual reality experience. As each individual perceives 3D audio in a different way, personalization of this experience is required. We have recently developed a low-cost and ef?cient HRTF measurement procedure that allows for such personalization. In this paper we compare two proof-of-concept prototypes, which gamify this measurement procedure: a lightweight mobile solution that provides intermittent visual feedback and a virtual reality approach which provides concurrent visual feedback. Results of a user study indicate that user performance is better with having concurrent feedback, although the concurrent feedback approach was perceived as less intuitive by most test subjects.
