Jason,

Any luck getting in contact with any of these folks?

Currently, as far as I know, you can’t buy this software. If you were to check out shaderlamps.com you can request a copy of their callibration software, and from what I can tell, it is pretty similar to what Johnny was using for his callibration technique (which he worked with a few of the shader lamps people with).

I have tried to contact johnny directly through the e-mail on his website, but no luck so far. I want to try and use this callibration technique in a real-world, entertainment aspect.

Being a VJ, callibration is not really that important, but to be able to transform a stage into something that is immersive both for the audience, and the performers, this would be absolutely vital.

I certainly hope that research continues for this, and it someday, soon hopefully, becomes available to users.

This is what I’m talking about all I want to know is how much and where can I buy this technology.

goodness!!! that thing rocks!!! it has many potential uses!!! It's great if they can develop dynamic calibration too(which is more complex to do)

Umm… Wow!

now add a pair of wii remotes and perhaps you could “draw in thin air”

impressive indeed - it is worth pointing out that this isn't new research (UIST 2004) - MERL and CMU have done some pretty neat stuff in the past. as a followup, they had a publish in UIST 2005 where they built on this where they added the capability to move the display in real time and increased touch capabilities ...

In the case of this demonstration, the calibration is not bing done in the projector. The video is passing through a computer first. The computer is processing the video and warping it to fit the projection surface. The projector is just being a dumb projector and not doing anything different.

where do you get the software

where do you get the schematics and the software cuz i got an old crappy projector lyin around

I really like the Hack-A-Day community because there is a high density of very smart people with an imagination that rivals or surpases that of the recognized research community.

The comments here about using high-speed DLP, infrared patterns, reflective markers, multiple surfaces, lost pixels are all completely spot on. Since this is my thesis work, some of these ideas have been addressed in my followup work. You can find that here (with more video!):

I think this is amazing but I don’t understand how it works. I have never seen a projector that has this sort of calibration via user-accessible menus. I mean, unless the team also re-wrote the projector code, I am stumped. I understand *how* the system works, I just don’t understand it’s able to tell the project to do anything other than zoom in and out, squeeze sides, or focus.
