With your budget...cameras are prolly not the way to go.
Cameras were introduced because they are cost effective to enable a big surface multi-touch experience.
You can apply the thinsight (google it) technology on a bigger scale to achieve what you want. Or get a capacitive screen manufacturer to make you one.
Thanks Hype. I googled thinsight and capacitive screen manufacturer, but with no luck. Do you know a name of a manufacturer i can look up to call and order one?
If I buy this, I don’t need a projector, IR LED ribbons, and the acrylic right?
