Unless I am completely missing the point here, this story about augmented reality plus personalization is a text message on a skin that just happens to be a chocolate bar wrapper Per Digital Trends : Augmented reality is the interaction of superimposed graphics, audio and other sense enhancements over a real-world environment that’s displayed in real-time. Based on that definition this does not qualify to be termed Augmented Reality.
It would be another thing if the message magically appeared on the bar of chocolate someone was physically holding in their hands. Imagine having the chocolate serenade you in the beloved's voice just as you were getting ready to unwrap it - now that would be more in the realm of augmented reality.
Some commenters have pointed out that some augmented reality chocolate would be nice - the satisfaction of chocolate without the guilt or calories. Or maybe when I am getting ready to buy chocolate augment the bar with information on a better snack option based on my health/fitness goals and lead me out of temptation.
