-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey everyone, I need some tips on parts that will give me the least amount of hassle in making a display that fulfills the EyeTap requirements. The display is for testing only and obtrusiveness, etc is not a concern. (ie I can look as borg as I want so long as it works and keeps costs down..) The idea (bit of a recap of EyeTap here) is a display will be reflected into my eye off a 2-sided mirror at an approximate 45 degree angle. A camera will be capturing video, bounced off the back of this same 45 degree mirror. The result is that the display image presented to the eye is the video direct from the NTSC camera, which is - by virtue of the mirror - effectively located "inside the eye". In other words the camera sees the same view as if it were physically where my eyeball is. Thankfully, it is not - it's actually off to the side, thanks to the 45 degree mirror. The image from the display presented to my eye is the video direct from the camera. Ideally, the field of view of the camera and display should match, so that the video image I see from the display/camera combo is the same virtual size as the mirror I'm looking into. Clear? So the mirror works like a "window". I'd be grateful for any tips on part selection that will allow me to select a suitable FOV lens, camera, and display to help me do this. Also, any suggestions on how to make some corrections if the FOV, etc don't quite match up? Finally, (and this is a tricky part) does anyone know of a filter or camera that is sensitive to IR in the ~780nM wavelength? (Or the best way to get what I want, which I will describe..) The idea is that I want to use an IR laser (this one below): http://www.digikey.com/scripts/us/dksus.dll?Criteria?Ref=66121&Cat=31261478 as a laser pointer that only the camera can see. And of course, I can see it as well when I look through the EyeTap which is the video from the camera that is able to "see" the IR laser pointer dot. So by virtue of the EyeTap setup, I can see where the laser is pointed (in the real, physical world) by seeing it through the EyeTap video feed - since if it's truly an EyeTap the video presentation and real world location of the video view that I see are one and the same. Right now I want to get that working so I can have a reliable EyeTap, and the "invisible" laser pointer working with it. Once that's done, I can get to processing the video with a wearable or whatever. I'd prefer to make this a do-it-yourself setup; budget of a few hundred, or possible trades. Thanks!
