Some pictures of the edge of the AuraHD are attached, if you look at them full size you should see how there are little ICs spaced all around the edges, I guess they would be the IR emitters.
When I look at my Aura, between the bezel and the screen, there is a narrow space which is set a millimeter or so back from the edge of the bezel. I had assumed that the plastic on the back of the gap was an IR filter which covers the emitters on one side and the receivers on the other side of the Aura (ditto for top and bottom of the screen). I have noticed that if anything gets into there (cat hairs, for instance), the touch screen can behave very strangely.
