how much would such a projector cost?

[pluehne]

@cooldawg10 The projector itself is a cheap one with a 800 × 600 resolution and costs $ 350 or so. To build such a ›touch-enabled wall‹, you’ll also need a Kinect (without XBox, ~$ 150) and a device performing the computations—probably the most cost-intensive part.

i'm new with all this stuff. Could i have a link how to do that or something?

[pluehne]

@MovieFan554 Have a look at OpenNI, NITE, and the Kinect Sensor drivers in order to extract depth and RGB frames from your Kinect. Once you have done this, you can process the frames using ordinary OpenCV methods.

Excellent concept to transform a other products into our daily working life...respect to the explanation from the author....good to promote a cost efficient method to 3rd world countries' school....blessing for the author
