<div>Hi</div><div><br></div>a bit of math.<div>average distance between eyes = 6cm = 0.06m (women = 5.5cm average, men = 6.5cm average)</div><div>football field distance ~= 100m. (give or take depending on which league, etc)</div>
<div>cloud height = depends on a lot of factors but lets say 2000m which is what wikipedia suggests is "mid range clouds" distance.</div><div><br></div><div>scale factor = 100 / 0.06 = 1666.67</div><div><br></div>
<div>so at a football field's pupillary distance a 2000m high cloud would appear 2000/1666.67 = 1.2m.</div><div><br></div><div>For where to cross the eyes I would guess a comfortable point would be around 1m in front of your eyes, so around 1666 m in the sky.</div>

<p>My thought was that the cameras won't be able to rotate a center point like our head is able to. Tying the camera rotation to the head movement instead of eye movement (which is what the cameras will actually be able to do in that scenario) might feel unnatural. Of course, tracking eye movement instead of head movement is a much harder thing to do, particular when your eyes will be covered with LCDs or something along those lines.</p>

<div>Um, if you moved your eyes (and the scene), it would be a strange feedback loop since your eyes are also looking at the scene.....</div>
<div>I suspect that if the rates of movement were set right it might work out for matching your head movement to the sensation. </div>
<div>You want to save the eyeball movement for moving around the screen. </div>

<p>I think that tying the position of the cameras to your head movement would cause vertigo or something similar, due to the camera rotation not matching what your head motion is doing.... what would be better is some way to track your eye movement and position the cameras that way. That way the camera motion would resemble what your eyes are trying to do.</p>

<div>You could put an accelerometer on your head so you an look around.<br>
<div>
<div>But unless the objects are vary far you'll want to work out how much to tow them in (when you look far and close your eyes cross inwards when seeing close). </div>
<div>That's the only thing that isn't really obvious. How to decide where the two cameras cross over. </div>
<div>I guess you could move your head forward and back and the accelerometer could control that?</div>
