The inverse optics problem as it pertains to the speed and position of moving objects. The schematic is a horizontal section through the right eye. As a result of perspective projection, an infinite number of objects (black dots) at different distances and moving in different trajectories with different speeds (arrows) can all generate the same 2D image speed. Thus, the information projected on the retina cannot specify the speeds and positions of real-world sources.
