Analyzed Objects?

I was recently looking at my stats for Halo CE Anniversary when I noticed “Analyzed Objects”. What are these? Are these things hidden throughout the campaign, or are they something else?

From what I remember reading about these a while back, I think there was some sort of function that you could do with your kinect device which would allow you to scan certain things in the game or something and it would give you information on it. I’m not 100% certain but a quick Google search might help you learn more about it.
