We finally have our multitocuh table/wall setup.
I say finally because we have been kind of late to catch up to the trend on this front, too busy doing other stuff.
This was just the first test. A couple of things still need to be adjusted but it works pretty well.
The app running is graffiti wall and we used Touche in this case as a tracker since it gives us 60fps with the firefly camera

    Super! here is the question. when I use LLP way. I found a problem some finger point cannot recognize. coz, other fingers can be blocked laser often. how did you set up for this problem. I think when you set up you might have got the same problem. :)

    and also if you use acrylics. it might bend that makes laser cannot spread widely. (sorry for poor english. kkk)

    you can watch my one as well. :)

    I think you can see the problem when I use tbeta calibration.

    if you position the lasers on all 4 corners there is very little occlusion. Did you do it that way?
    Yes the acrylic has to be thick enough to not bend or you can put a supporting frame around it.

    I see. In your case, you put 4 lasers at the end of corners, am I right? actually I put 2 lasers. :)

    ans also I bought second-hand lasers. coz, I couldn't find good and right lasers in korea. if you don't mind could you tell me links to buy right lasers from online shopping mall? or if you don't mind could you tell me all you use equiptments list and where you bought? ^^

    and how did you fix position for Laser?

    thx your help. :)
