So, we’ve been madly purging in preparation for this move. It’s still quite difficult (though I’ll have a whole mess of computer equipment to offer up shortly. Blog readers get first dibs, though I suspect I’ll have to go to freecycle to get rid of it). Anyway, I came across a few grad school notes and papers, one notebook of which was full of various labs, tests and notes from my Perceptual Psychology class — relevant to virtual worlds, of course. In there were notes from a lab on the demonstration of the blind spot — something that also came up in my physical exam for my pilot’s license (No, I’ve still not flown in years, but I’ll get back to it soon, I’m sure!). I’ve mocked up the experiment here. It still amazes me how little of the world we actually see compared to how much we think we see.
Close your right eye… Look at the cross-hairs on the right. Start with your head about a foot from the monitor. You should be able to move your head forward (or backward) a little ways until the quarter disappears.
