The shelves have eyes

You could now be allowing your local supermarket to study your shopping habits while also allowing them to know your gender and age. Big Supermarkets are now using Microsoft Kinect to record your gender and age and they proceed to record your shopping habits.

This is very similar to when Ogilvy Hellman's teamed up in Brazil to print out recipes based on the rest of the items on the receipt whenever someone picked up Hellman's mayonnaise.

This is definitely something that is going to change the future of grocery shopping and supermarkets, however I'm still not sure if this will benefit everyone or just make grocery shopping really annoying.
