Cameras A variety of cameras can be used to create cine-VR images, including traditional cinema cameras in conjunction with a panorama tripod head. Most commonly 360° cameras are used, allowing the storyteller to capture the entire 360° space at one time. 360° cameras use multiple lens combinations to capture all portions of the 360° image simultaneously. Those disparate images are then combined into one 360° panoramic image using a process called "stitching". If a single lens faces in one direction, the image is referred to as monoscopic. If two lenses are used for a single direction, the image is referred to as stereoscopic. Stereoscopic imaging creates a 3D effect. This technique leverages the parallax difference between multiple lenses to achieve the illusion of depth. Stereoscopic content is generally contained within one media file with the images stacked above and below each other or in a side-by side-fashion. Audio designer Simon Goodwin describes ambisonics, as "a generalized way of representing a
soundfield—the distribution of sounds from all directions around a listener." Ambisonic audio recreates the soundfield spherically and is uniquely suited for VR applications because it provides motion-tracked variations of audio signals and enables sounds to be positioned anywhere around a user—up/down, front/back, left/right. Properly implemented, Ambisonic audio allows users to move their heads and bodies around in the soundfield just as they might turn to look for the source of a sound in real life. As users glance around, the headset uses motion tracking to alter sound direction and quality.
Head mounted displays Cine-VR should ideally be played on a
head mounted display (or HMD) with headphones. While in such a headset, most surrounding distractions are visually blocked out. HMDs have built-in hardware sensors called gyroscopes and accelerometers to move the images in concert with the audience moving their head.
Gyroscopes track how much something is tilting and help to smooth the graphical playback to prevent videos from shaking.
Accelerometers measure the actual movement in space. The combination of these two can precisely track the device's position and orientation. Along with optical or infrared tracking, gyroscopes and accelerometers are integral parts of the VR headsets' tracking capabilities and increase immersion. In contrast with the other mediums, "immersion" is still the main experiential value that the experts remark in cine-VR. This is achieved primarily through head mounted displays used to view its content. ==See also==
