Project

3D audio personalization for virtual reality applications.

Our previous research resulted in a low-cost and user-friendly do-it-yourself method that allows a user to measure their Head Related Transfer Function (HRTF) at home. While it is recognized that personalized 3D audio can add significant value to VR applications in a Business to Business environment, e.g. VR safety training, it appears that in addition to an efficient way of personalizing 3D audio, i.e. an HRTF measurement, two more elements are missing. First, the user having to assemble him/herself the measurement system from a number of commercially available components is perceived as a major obstacle. Second, the absence of standard software allowing effective use of personalized 3D audio acts as a significant impediment to its exploitation in applications. In this project we propose to remove these two obstacles to the use of personalized 3D audio in such Business to Business applications. The first obstacle will be addressed by developing a hardware module capable of capturing and transmitting both head movements and binaural microphone signals to a smartphone/laptop. In addition, we will extend Unity, a development platform widely used in the VR and game world, with a 3D audio module. This software module will allow application-developers to include personalized 3D audio in a standardized way in their products. Users of 2 these products can then upload their measured HRTF and experience the advantages of personalized 3D audio.
