    just want to know, is it still possible to play light gun games through a projector using the light gun as the controller?

    I dont think it is due to the way light guns work, i cant or dont know how to post the link to the thread but if you do a quick search there is some great explanations as to why.

    yeah that was what i was thinking, the technology or the way the gun transmits the signal to the screen will not be absorbed or read by a systematic trigger, i.e. targeting the light gun towards a certain part of the screen and shooting.

    just wanted to clear this up for myself, but since you guys says it wont, and also by the way youve contributed the fact that there is evidence or a source to a reason why this is, then i believe yah, thanks anyway guys, james

    I have read that article before.

    You can get light guns that will work with 100hz screens now I believe. But they still wont work with LCD / Plasma / Projector RPTV displays. Only CRT sets.

    Its just a limitation of the tecnology. There are so few people using this sort of technology in real terms I guess it will be a long time until somone comes up with a lightgun that works with them :(

    *sigh* I would just love this to be possible, but I'm thinking that without the whole raster-scan-redraw-thing happening, there is no way of working out where the gun is pointing.

    If I understand the way they work with existing systems, we can't see the picture being drawn 50 times a second, but the gun can and it can time how long since the start of the frame before it lit up the bit of the screen the gun is pointing at and, so, it can work out exactly where it is.

    Projectors don't work like that, though. I wonder if some techy person out there could explain if it's even possible to do something similar? Component signals do have a timing element (synch on the green usually?), but the screens get displayed all at once?

    I guess the guns would have to be much more sophisticated and take a much more detailed 'picture' of the bit it's looking at and do a load of very fast comparison processing.... hmm.... sounding very iffy....

    Unfortunately it can't currently be done which is a hell of a shame as can you imaging how much fun it would be blowing the virtual crap out of terrorists on your 8 ft screen :D . If some genius could ever devise a way then I think that we would have one of the best gaming experiences that you could have in the home! I guess the screen size is the constant so you essentially need some device (maybe a camera like eye toy) that scans the screen to pick up where your IR beam is hitting the screen and then relays that to the game so that where you actually hit on the screen relates to the actual position you hit in the game. It would need to be callibrated but i'm sure something like that could work.

    I think I get why they wont work but am not 100%.

    I have an RPTV and projector so have no way of using a light gun.....but if it is not possible to use them on RPTV's then how do so many arcade machines which use RP screens work? Do they use a different technology for the guns or something?

    It wont work and never will and its a reall pity. House of the Dead 2 and Confidential misson on the DC are still awesome :(

    Fundementally they way the technology works for existing light guns is not compatible with projection, Plasma or LCD Screens. :(

    sorry to burst all your bubbles but it is possible to use light guns on plasmas lcds projectors etc etc etc. You just need the right gun. Note that with a projector you may end up standing inbetween the projector and screen (slight problem in some peoples books....)

    Anyway if you want the gun that will work with the above displays it costs £40 for all consoles and you can get it from here:

    My mate bought one in the US and he said it was very user friendly and very accurate. Not much else to ask for, perhaps a paint job is necessary though. If id seen this thread before I would have posted this link earlier, ive known about the gun for a good 4months now...

    Yes wow :eek: . Thats new for sure. And its Wireless ! If it worked with the DC as well I would definately buy it. I might still get for House of the Dead 3 on the xbox to use with my Plasma.

    Thanks for the tip !

    I dont suppose you can pull a DC light gun that is compatible with Projectors / Plasma screens as well can you

    Lol might aswell email them. I emailed them a while ago and they were considering providing extra connections for other consoles. It wouldnt be too hard for them to implement, Im just not sure how many (if any) of the DC games would support it.

    WOW!! That's great - i'd like to hear first hand off someone who owns one but if it works on a PJ screen (like it says it does) this will be superb!! :thumbsup: Seems I wasn't too far off with my idea of using an Eye Toy style camera :smashin: .

    You were spot on, mate - I'll let you know how it goes!

    It says on the site that "you place the sensor on top of your TV" so I'm a little concerned that it may not be optimal when placed under my pj screen, but we'll see, I guess!

    You cant put it underneath the screen because of how the camera sees the gun. It may work to the side but unless you hold the gun upside down I dont think it will work on the bottom.

    Yeah the thing works by a spot of triangulation by the look of it. It tracks sensors on the sight on top of the gun and in the barrel of the gun to map out where the gun is and where it is pointing in relation to the screen. I would guess that the camera would have to be situated on top of the screen and in the middle.

    With this sort of technology you could make some amazing shooting games. If you had sensors placed say on your shoulders then the game could map where they are so that you could actually move infront of the screen to take cover!

    I have a freestanding PJ screen so I could actually mount the sensor on top of the screen without too many problems.

    But I really want it for the Plasma as this is where the Xbox is setup currently.
    Stuff like this is getting us closer to total immersion. Proper VR style integration is only 10 years away for this sort of stuff I reckon.

    Is the manufacturer US or UK out of interest.

    Oh, darn it, why didn't I spot that site page? :( Here's hoping the cable is long enough to reach up to the top of my screen (the ceiling!)

    Now if you combined this technology with 3D virtual reality glasses (like the eDimensional ones) you would have one hell of a virtual reality experience! :thumbsup:

    Its comming for sure but we are a few years away yet until its mainstream. I remember System Shock had a VR headset option, that was well over 10 years ago and it worked well apparently. I am surprised more has not been made of the technology to date.
