Multitouch Driver Windows 7

I was looking for a multi-touch driver to use in Windows and it took some looking obviously enough to get one that worked the way it should be.   One that emulated the touch ability of a typical Windows 7 tablet.

This is for my Multi-Touch Gaming Table experiment.  Speaking of which I do have an update, Deal Extreme takes forever to ship.  It was over a month from the time I placed my order before I received the 48 IR LED security lights.  Both of which worked by the way, I cut the existing plug off and used an old PC power supply (i have a lot of them) to power them.  Just wire the red wire from the lights to a yellow wire from the power supplies main lead (the big mass of wires) or the supplemental power lead (small square plug).  Then wire the black wires to any black wire for a ground.   To get the power supply to turn on short circuit the green wire in the main plug with any back wire. I just clipped and soldered them together.   Unfortunately the lights help but not enough.

I'm thinking I may have to just bite the bullet and get a piece of Endlighten and some strip lighting and deal with the loss of Fiducials.

Anyway, after putting the table on hold for a month waiting for the IR lights I went back to getting it working again using some IR pens I made.  It's not great but it's better than nothing right?

So I found this - http://multitouchvista.codeplex.com/ The instructions on the site are for getting it working with multiple mice.  I offer the following instructions instead since they're not obvious nor posted anywhere.

Install the driver as posted on the site.   Then run the two console files, the MultietouchDriver.console and the Multitouch.Service.Console.  I DON'T recommend the open Pen and Touch and then checking the show mouse box that is listed on the site, that puts a virtual mouse on the screen.  Not really what we're looking for here.

Then open the MultiTouch-Configuration.WFP app and click TUIO and then the obvious option.  At that point the WFP file crashed on me but it did flip it from MultiMice to TUIO input.

Now close the driver and service consoles and fire up CCV.   Calibrate it as normal and minimize it or whatever.

Now re-run the two console apps above.   The reason you don't want them running when you calibrate CCV is it turns the long press of the calibrate procedures into right mouse clicks and if there happens to be anything on the deskop, a window, icon, whatever it jacks around with you by right mouse clicking it.

With those simple but not obvious steps you should now be able to use touch on your table and control windows.  A double touch is a left mouse click, a long touch is a right mouse click.

I'm having issues with calibration at the moment.  I get steady seeming blobs with the pens, the ID doesn't change but it can take an ass load of attempts to get the calibration to work as each point requires a bunch of attempts to try and get the blue sweep to go all the way around.   Annoying as hell.
