Interocular, meaning distance between a pair of eyes/lenses
For example, if you wanted to shoot something from a cat's POV, you'd put the lenses closer together and shoot objects closer to the camera. That would make it easier to fuse images of a mousehole right in front of your face. Things farther away would simply look "less 3-D" and therefore abnormally far a way to a human viewer.
Instead I assume they're using the pair of lenses to approximate a 3d model which allows for display at a variety of angles (all reasonably close to where the camera is), and then rendering from that model for the person looking at the image based on the angle they are actually looking at it from. Which solves the interocular distance problem, because you render for each eye based on where the persons eye is resulting in a distance between the two display images that doesn't have to match the camera.
