| Outline of Annual Research Achievements |
The main goals of this research project were accomplished during the fiscal year 2018. They are as follows.
1) A virtual environment for psychophysical experimentation was assembled. The system captures and reproduces 3D ambisonic audio and 360 video. Ambisonic audio facilitates the digital tracking of head movements, which is important to increase the sense of presence during reproduction.
2) A collection of immersive contents for headphones and head-mounted displays has been created. They have been captured in anechoic and natural environments, and are intended to be use on subjective tests in future extensions of this project. The contents are publicly available at the project's website: https://cesardsalvador.github.io/projects.html
3) The international collaboration with Tsing Hua University and Hannover Medical School has been initiated to explore the computational aspects of the brain processes that are involved in auditory tasks such as the localization, identification, and selective attention to sound sources.
4) The HRTF dataset of this project has also been used in psychophysical experiments of auditory attention along distance. This has been done in collaboration with colleagues of a different project.
5) An international workshop has been organized and held in Lima, Peru, to present the achievements of this project. This was done in collaboration with "Universidad de San Martin de Porres" and "Fundacion Telefonica". The language of the event was Spanish. The full event was recorded and is publicly available at this link: https://cesardsalvador.github.io/a3d/
