Hi gang, not sure if this should be here in Sensors, or in the Interactive Art section.
I'm working on a an interactive light piece which is basically a large tower covered in windows:http://www.technoetc.net/imgs/urbana_2011_gameplay_2.png
Each window will be translucent acrylic, and illuminated from behind. To provide interaction, I'd like each window to be touch sensitive. I'd like to use a capacitive sensing approach, but not sure if this will work until I do some experiments; I fear over such a large area capacitive sensing will be very noisy.
In the meantime, I'd love to hear any suggestions anyone might have as to how to detect users touching the windows. I'd like to avoid having to use little buttons beside each window
Light or ir sensors might be an option, but I imagine will require a great deal of calibration.
The piece is still in the design stage, so I'd love to hear your suggestions/comments.
