<i>Minority Report</i> tech is here: smile-detecting vending machine

Our world is getting to be more like Minority Report every day. Now Unilever, international conglomerate that makes about a half-dozen brands of ice cream, created a vending machine that gives the stuff away, but there's a catch.
This benevolent machine is called Share Happy. It first entices you to position your face atop a graphic of a cartoon character, and once it's detected your face, it promises to give you free ice cream if you'll just smile at it.
Its sophisticated face detection system discerns your age and gender, and then figures out your state of mind by reading your facial expression. With its 3G connectivity, it offers you the chance to upload a pic of your smiling face to Facebook. If your facial expression registers big enough on its Smile-O-Meter, it rewards you with some tasty free ice cream.
What a great way to bribe people into advertising your product on Facebook! Still, for some of that tasty Ben & Jerry's ice cream, it might be a worthy exchange.
