For the next course I will briefly go back to the topic of perception of depth to understand the perception of movement.

I have updated the slide9 of the perception of depth (Fishtank VR) as there was some questions about the difference with slide 6 on motion parallax :

To understand the difference with the mechanism described on slide 6, it's important to remember that on slide 6 the motion parallax phenomena characterize the displacement of real 3D objects on our retina whereas in slide 9, the displacements are those to compute on the "window" through which we see the virtual world. Make the parallel with a real world window through which you observe the landscape ; if we want to replace that real window by a screen simulating what you see through the window, slide 9 describes how to display landscape entities on that screen when you move your viewpoint relative to the screen.
