Hello All,

Hoping to find someone out there who can give me a lead on this.

Here is what I am imagining.

My storefront windows will have a few large computer displayes in them. Passersby will be able to interact with what is on the screen.

They will be able to browse my showcase listings, do basic searches and see the results, etc.

The part of this solution that is missing is the method the passerby will use to interact with the computer.

I have seen super-durable keyboards - but those ultimately get vandalized. I don't need a full keyboard here, just left, right, up, down and select. Maybe a cursor control device.

I was wondering if there is something that could actually be attached to the inside of the window that would detect the users finger on the other side of the glass to get input. I have seen a cool little thing that makes your window a touch screen, which is kind of cool. But this technology is not really available yet.

Any suggestions?
