A new lightgun?

BadMouth:
There are also a lot of people in this hobby that clamor for products to be made and features to be included, while having no intention of buying it unless it's dirt cheap.

EDIT: Someone get on my idea about interweaving targeting reference frames on a high refresh rate monitor.  ;)

I have a CRT in my Mame cab and I for the life of me can't find a decent light gun for that... let alone one for a LCD.

PC based or console based?

On a side note hes done another video with Virtua Cop and no crosshairs.



The border is more visible in this one but does not take away from the game I dont think, Hell you are only really going to notice if you look for it 99% people prob wont even notice it.
MrLightgun:
Hi everyone

This is my Kickstarter and I've been encouraged to join the discussion.  I've been trying to avoid joining threads like this because it can be seen as self promotion and get the thread shut down.  I've joined this thread, firstly because I was encouraged to by a member but also this is a very knowledgable thread with some obviously smart people contributing and this type of feedback is incredibly useful and appreciated.  I'll focus on the technology discussion rather than trying to sell the product!

I'm going to attempt to answer some of the general questions in the thread:

1) Accuracy:  The accuracy is perfect, if you truly understand the concept then you should understand the accuracy is perfect.

2) Lag: In normal usage you don't need the crosshair (because it's super accurate without calibration).  This removes 33%-50% of any lag seen because you don't need to wait for the display to update.  I only show the crosshair on the videos for people to follow what is happening and show the accuracy of the gun.  On my initial videos I didn't realise quite how laggy this looked.  I had the windows mouse animation speed set at around 75%.  Maxing this to 100% helped.  You can see now on my virtua cop video how good performance is in a real game.  The response time is less than 2 frames and would probably be less than 1 if a high speed camera was used which is obviously the plan in the future.

3) Original Vagueness: Yes this was a mistake, I thought the internet would enjoy debating how it worked but in fact it meant people said it was fake or too good to be true!  I've obviously learnt from this so now have given more details and also try to show more the type of content people have suggested.  The feedback from places like here has been incredibly useful and I have taken it on board.

4) General performance: The gun just works, it doesn't get confused, it's accurate and fast.  I wouldn't put myself on the line trying to release a product that I didn't think was already awesome.  If I got the opportunity to do a public demo that would really help, I'm not managed to get any media interest yet although I burnt the first week having to redo all my content so I need to focus on that now.

5) Cost of product / Kickstarter target: The device needs good quality components to work and therefore the margin on the gun is not huge.  Therefore I need a high target to pay for all the bits that need paying for.  Not sure what alternative I have, I've tried to be as honest as possible.

6) My hypothesis is that Lightgun games have disappeared because the current technology does not give the same user experience and therefore is not as fun.  The key is missing the line of sight functionality (Wii) or having to calibrate (PS3 Move, Aimtrak etc) which seems to be widely accepted is not 100% effective.  My innovation can bring back the ease of use (no calibration) and fun (line of sight) of the gameplay mechanism.  A border (worst case) is a small sacrifice for this, in my opinion of course!  This is why my grand plan is to bring back the Lightgun genre.

7) Distance to the TV: I've only just realised what a key feature this is in the last few days as I was unaware how big an issue this was on other technology.  So ideally the Lightgun needs to see 2 widths of the tv, so if you aim to the far left of the tv in the centre of your video frame, the right hand side of the tv is still in the frame BUT if you are closer and you chop the edge off the edge of the tv you still see a rectangle with what is left.  So you still know you are at the far side of the rectangle and therefore at the far left.  In reality this slightly lowers the horizontal accuracy.  However if this is key functionality the software can identify the width of the tv frame when you have the whole tv in the frame and therefore when it gets chopped off still base it's calculations off of the larger size and therefore give accuracy.  This would enable you to use the gun much closer because you only need to get just over a televisions width in the frame.  The sacrifice would be that it wouldn't work so well from angles at this distance but it doesn't sound like this would be a show stopper compared to the overall benefit.  If it continually updated the tv width when it sees the full frame then if you move position it should still keep its accuracy.  I would consider the accuracy as almost perfect (99%??) because there is guess work involved, rather than perfect when it sees the whole frame.  With other products once you can't see see some of the raw LED input you are stuck as you can't infer. 

8) CRT: It should work on CRT, I never really thought of the demand for this because I thought original lightguns would have this covered but I guess the PC solutions are not as perfect as the more advanced console lightguns.  If the screen is a flat screen CRT it would definitely work.  If it was a very curved old style one I guess it would come to how rectangular the image was.  Probably be more restricted on your angle and you need to be head on.  However the technology can be adapted to do something else such as putting markers in the corners instead of a rectangle.  So yes the technology should work but unsure about my current software implementation.  Any photos of people's CRT with a full screen game on would assist the discussion.  Maybe warping the original border so that it is rectangular after it is output might do the trick.

Please ask any other questions you have and I'll do my best to answer, thank you all for taking the time to look at and feedback on my Lightgun technology. 

If you could post my project on any forum or groups it would be massively appreciated.  You don't have to instruct everyone to buy it but just raising it for interest and discussion like this thread would be great.

Thanks

Mr Lightgun




Mike A:
If your margin is low you will fail. You cannot manufacture and sell a niche product for low margin.
If the price is too high you will fail. Everyone says they want a product until it is time to pony up the dough.

If you take Titchgamer's  money and run to Tahiti, I will hop on a plane and burn down your grass hut. I know how this Kickstarter thing works.
