Programatically, yes, for the most part.

I see it like this from a user perspective:

Step1: Vertical center line shown to user for top and bottom placement. User instructed to place LEDs in-line and as close to screen edge as is practical.

Step2: User is prompted to enter top/bottom offsets and distance between the 2 LEDs, with emphasis on accuracy. The more accurate the better. No rounding.

Step3: Program calculates the correct vertical offset for the left and right IR LEDs and places a horizontal line on-screen at that location. User instructed to place LEDs in-line and as close to screen edge as is practical, keeping the same distance between the LED and the active screen edge on both sides.

From that point on, it should just be fine-tuning by whatever means is most practical. I haven't gone far enough in the setup process to see exactly what that entails. But if you already have the ability for the user to enter offsets for the LEDs, and the Wii remote camera has the ability to see them, I can envision using the information from the setup process to place a representation of the physical LED pattern on the screen and then instructing the user to position themselves and the "camera" to try to align the blobs seen by the camera as close as possible with the ones on the screen and pulling the trigger. At that point, the software could automatically calculate the offsets between each. If anything still needed tweaking, you would still have the ability to do so.

Maybe that last part wouldn't work for how you are doing things, but it's something I would personally try as an experiment.

Fusselkroete:
But many ppl had no problem and managed to master the calibration process and have perfect aiming. Its only one time calibration so all is good ;)

BadMouth:
Randy, maybe reserve judgement until you've actually set is up and used the calibration. It could be that I just didn't wrap my head around it completely and made it out to be harder than it is.

Yeah, I'm a "fixer" by nature and it looked like there were some aspects you encountered which might have benefitted from some input. But in the end, it's a process which only need be done once. So as long as the system works well, which it appears to, that's all that's really important.

Just so my comments are not misunderstood, Fusselkroete's work on this is greatly appreciated. I think it will make good lightgun gaming far more accessible to gamers than possibly anything has in the last decade or so. IMHO, it deserves more attention than it appears to have received so far. Hopefully that situation changes as more start using it and the "word-of-mouth" kicks in, which will hopefully encourage him to take the software further.

As a side note, my Nyko "Perfect Shot" gun shells showed up today. They feel great in the hand, are not bulky at the forward part and the trigger action is excellent. They even have a port pass-through extension which brings it down below the grip. I have another style on order as well, but the Nyko's will be tough to beat. My only complaint with them is the lack of a bead on the clip in front, which you really can't fault them for. The Wii never really had good line-of-sight aiming, so it wasn't really necessary. I think a small, well-placed divot, a BB and a drop of superglue will take care of that nicely. Now just waiting on the LED modules :)

RandyT:
I couldn't help myself. Based on my earlier ramblings, I made this small app for myself to try when the time comes. It might work, or I might have just wasted my time. :laugh2:

BadMouth, if you feel like it, go ahead and check this little program out and see if the result points to where your LEDs are stationed. If not, then we'll know it's useless and I'll delete it. Otherwise, it may help a bit when it comes time to move your LEDs to your cabinet. It's resolution agnostic, but should at least be used at the native aspect ratio of the display. Also, at low resolution some of the screen elements might trample each other. Outside of that, it's been tested and based on the test measurements, it looks like it does what it should.

*edit* Software used some bad math. Will update in a later post. :-[
