I noticed the non linear x tracking as well, but I noticed it only happened when i moved the gun by rotating my body. If i kept the gun as the pivot point, the cursor and sites always lined up. I would expect you'd need some kind of tweak to compensate for the gun rotating about a fixed point (the player) a fixed distance from that point. Possibly a modified calibration routine could take this into account. --- End quote --- It would actually be possible to completely compensate for this. But, this would introduce an error when moving physically back or towards the screen. So the present firmware (which is not the one being shipped as I want to add some more tweaks) gives a happy medium between side to side and front to back body movement. |

It's one user's experience and may not be the same for everyone/anyone else. I'm not saying it's perfect as I haven't had a chance to fiddle with mine yet. --- End quote --- I'm not basing everything on just the videos. Most are saying that the difficulties are similar. Whether or not they are concerned about it seems to be the variable. FWIW, I'm hoping my experience is different as well, and if it is, I will be the first to tell the OP to send their unit back for a good one, or try it on an LCD screen (which he should do anyway, if he has one available to him). --- Quote from: AndyWarne on October 14, 2009, 02:10:20 pm ---I think you will find that you repeated my idea, ie to position the cursor a known distance from the edge and have the gun aim at this rather than the edge of the screen. Maybe read the posts again... --- End quote --- Actually, I did read your post. Mine was in response to it. You were concerned about the static cursor image being hard to see or being off screen. Moving it in a box formation 10% in (which should accommodate any overscan situation) should address both of those concerns, without a negative impact on accuracy. A quickly moving mouse cursor forming a small box is also a better target to aim at for calibration purposes. --- Quote ---Have you used a reasonable mobile phone camera recently? I dont think you will find any noticeable picture distortion. --- End quote --- As I said, I put it out for consideration. In a mobile phone application, a little edge distortion is no big deal. In an application like this, where you might be using a small section of the CCD at the very periphery of the lens, not for simple "artistic imaging" but for coordinate use, and it could be. But some scrutiny of the raw data will flesh that out. If that's not the problem, be happy :) RandyT |

Anyone want to hear my impressions of this thing, or am I going to be accused of being a jerk? |

Got my 2 aimtrack modified guncons today, looks pretty sweet! The following are my INITIAL thoughts on this, some issues I've come up with, without having put much time in troubleshooting them. I suspect these issues will work themselves out. #1 - poor calibration: Issue: the gun was not very accurate and I was having issues trying to calibrate it. For example, it was having difficulty registering the trigger for the top right corner. Solution: I was concerned that my 19" LCD at about a 70 degree tilt was the culprit. First, I turned off all external lights (in case of a leak heat source) but that didn't help. I then proceeded to check out the Ultimarc website and remembered that the LED pins need to be pointing at the gun. As my monitor is not at a 90degree angle, I needed to bend the LED's towards the gun (as documented). So I did so, bent them pretty much as far as they could go, tried it out and ... SUCCESS! I was able to do the calibration and right from the get-go, I'm super impressed with the accuracy. Can I say it's perfect? No, but I’m not getting the half-inch error rate that was mentioned before and that’s with the stock firmware (I think it was mentioned there was improvement in this area?) #2 - buttons not responsive: I tried Operation Wolf, it tracks near perfect, but the trigger sometimes won't respond, sometimes the bottom button (under the handle) will work as the grenade button (whatever it is) most of the time it won't. I had trouble getting OpWolf to recognize that button in the menu (had to hold it a while). Solution: None yet but I believe I might know the cause #3 - the aimtrack config utility says the gun is not connected (but the mouse cursor is moving, controlled by the gun!). I also get a similar message when trying to use the firmware utility. Solution: None yet but I believe this is tied to #2. What I believe is happening is the gun I am using is plugged into a USB extension cable, which is plugged into a USB hub, which itself, is plugged into a USB cable extension, which itself is then plugged into one of the ports. Because of the type of USB hub I’m using, I HAVE to use a USB extension cable, but maybe the one I’m using is too long. I’ll experiment and will try and plug in the USB hub directly into the USB port (just letting it hang there for a bit won’t cause damage). Anyway, I've already got ANOTHER USB hub inside the cab because of the use of U360’s, the USB trackball and the USB Spinner so maybe I'm pushing it a bit with a second hub, though it's never been an issue before when I was using the Whatever the case, I'm pretty sure the guns are fine, I'll also try the other gun. I think someone mentioned an issue with the LCD Topgun driver, so I will also remove that, just in case its interfering. Whatever the case, initial impressions are very good, tracking wise I was accuracy on par with the LCD TopGun’s (which I got good success) but at half the distance! It’s true though, you really have to keep the gun within a certain distance from where you calibrated but this is no surprise and is a non-issue for me. I'll have to hunt down some arcade gun holders that I can attach to the side of my CP so that they could be holstered when I don't use them. Anyone know if there are some that will fit well with the guncon’s? More comments coming… edit: Just thinking about accuracy and the "half-inch" mentioned before. It's true that I'm using a 19" monitor so if there are some accuracy issues that come up, it's possible they will be lessened because of the smaller sized monitor I am using. Whatever the case, works for me so far. |
