3D spatial video, based on the provided definition, is essentially a form of side-by-side 3D video.
Understanding 3D Spatial Video
As defined, 3D spatial video provides viewers with a sense of depth. This depth perception is created through the side-by-side format.
Key characteristics highlighted by the definition include:
- Side-by-Side Format: The video is presented in a way that utilizes two slightly different perspectives shown simultaneously to the viewer, typically one for each eye.
- Sense of Depth: This side-by-side presentation tricks the brain into perceiving a three-dimensional space within the video. Objects appear to have distance from the viewer and from each other.
- No Head Tracking: A crucial point mentioned is that nothing happens as you move your head around in space. This means the perspective of the video remains fixed relative to the screen or headset, unlike more advanced spatial computing experiences where the view changes as you physically move your head to look around the scene.
In simple terms, it's a video that looks three-dimensional (has depth) but doesn't react to your movement within the physical space you are viewing it in.
Practical Aspects
Viewing 3D spatial video typically requires:
- A display device capable of showing 3D content (like a 3D TV, VR/AR headset, or specific monitors).
- Appropriate viewing technology (like 3D glasses for TVs or the headset optics).
Unlike truly interactive or volumetric content, this type of video playback is a passive viewing experience focused solely on adding a layer of depth to traditional video.
