AR can be offered to users via headsets like Microsoft’s HoloLens, or through the video camera of a smartphone. Augmented reality – or 'AR' – allows the user to interact with both the real world and digital elements or augmentations. Audio design and production are more important for VR than previous display methods, and "3D sound" will make most virtual reality experiences all the more convincing and immersive.Īugmented reality is the overlaying of digitally-created content on top of the real world. While ambisonic audio does potentially mean more expense – both in memory and production budgets – it grants your VR experience a fully immersive soundscape. Ambisonics are commonly paired with 360-degree videos and used as an audio skybox for distant ambient sounds. The sound field can also be decoded into a format that matches the speaker setup. The sound field can then be rotated based on the listener’s orientation – for example, the user’s head rotation in XR. Instead of each channel mapped to a specific speaker, ambisonics instead represent the sound field in a more general way. Ambisonics are stored in a multi-channel format. Officially a "full sphere" technique, it also serves audio sources positioned on the horizontal plane. This surround sound technique covers sound sources both below and above the user. While some of the production of 360 video is distinct from building from digital assets, the post-production process is relatively comparable to creating gaming and other digital MR content. Interactive 360 videos are experiences where the viewer can interact with the UI or other interactable elements using gaze or a controller.ģ60 video is an opportunity for creators to work with a variety of industries now wanting to provide content in a marketing or entertainment form. Non-interactive 360 videos are experiences where the viewer cannot influence the viewing experience outside of perhaps pausing the video or moving their head to take in different "camera angles". ![]() After being prepared for display via a technology such as a 3D game engine, 360 videos are then viewed by the user in a headset.ģ60 videos can be non-interactive or interactive. 360 videos can be live action (cinematography or videography that does not use animation), animated (captured from a 3D scene), or a mix of computer generated-graphics and live action. They are typically shot using a specialist omnidirectional camera, or a collection of separate, connected cameras mounted as a spherical array.
