That would be a good solution, so long as the monitor isn't too large. The vertical and horizontal FOV of the camera is supposedly different by about 10 degrees, so using it sideways could require greater distance from the monitor to get good accuracy. Maybe paired with a wide angle lens.

But I don't think I could see myself using the trigger in the off hand. It's weird enough holding a miniature BT game controller for the reload function (which I do currently) but it's better than the alternative.

*edit* Maybe I misunderstood the nunchuk comment there. It may be possible to incorporate one into a grip, so long as Lichtknarre gets the button reporting under control. Currently, I haven't been able to get pretty much anything other than the test area in Lichtknarre to recognize them, but I haven't tried it with vJoy....maybe they work in there. This arrangement (with the remote in normal orientation) is used in the Cabelas "shotgun" shell, so it could be an approach to take with some cable management somehow. That said, I was never thrilled with the "button as a trigger" with that unit, but I'm picky :)

BadMouth:
Yeah, was thinking of the nunchuck connection as an interface for trigger and other buttons incorporated into the grip. Just as in interface so hacking the wiimote would not be required.

Howard_Casto:
It's certainly an option. Nunchucks are far cheaper and are easier to hack up. I like those guns you linked to but unfortunately you can't buy them anymore. I've looked so if I'm missing something please tell me. Shells seem to be the only things that are readily available. In terms of gutting the wiimote, the pcb would need to be in the original orientation. I mean all the positional data would be off and it'd be a pain in the ass to correct. The thought had occurred to me though, so I went on the fleabay looking for arcade shells. Eh they are a bit pricey. Not sure why as most are junk, but it'd get things up into the "it's so expensive you might as well try one of the diy solutions" category.

I've been looking at the aliens extermination guns on aliexpress. They'd be good shells for a larger gun setup but the shipping on even the shells is insane. It's a shame as they'd make terrific positional gun controllers.

I honestly don't believe it would be that difficult to allow alternative orientations. Each frame of beacon data would just need to be normalized (due to the way the camera scans for them) and the appropriate offset direction applied, based on the selected orientation. The only place it could get tricky is the accelerometer. If it happens to work better in the normal orientation, then it may not be ideal to use a different one than specified by the manufacturer. But even this seems unlikely.

If the tracker plugin framework is open-sourced, which it probably will be at some point, this type of change could even be implemented without touching the main code. Lots of possibilities at that point.

Howard_Casto:
I'm referring to the accelerometers. Any math used to take their data and improve position calculations would be off and it'd take a re-write to fix assuming now that the wiimote's resting position would be on it's side. Or we could just not be jerks and use it in the proper orientation.
