New to this site so hoping it's the right place to ask.
I'm trying to prototype something for use in a retail store and an idea a teammate had was using an RGB sensor to detect both ambient color as well as a proximity sensor to detect when someone is near the display and get the color of their clothing. We'd then use a series of LEDs to recolor the display to match that customer.
The problem I'm running into is that most RGB sensors I've found seem to only be accurate at a few inches (at most) and for proximity sensors it's a bit better but not enough for use in a store setup.
I have a pretty limited electronics background though so I'm mostly browsing Arduino suppliers. Does anyone know if you can get sensors with a larger distance and if so can they be controlled by something like an arduino?
One potential fallback is a camera like the MS Kinect with a full on computer but the client is weary of having a real camera for legal reasons.
