343 Industries detailed today how Kinect integration will figure into the Halo Universe, including use of voice commands to reload weapons and throw grenades, and a gesture-based system to access an item database.

That is awesome Kinect integration!

Random Scanning FTW

I like the analyzing option and collecting things in your library. Probably won't use the 'grenade!' feature though ... my nephew might enjoy that/

Pretty much this but swap out nephew with kids.

I will be interested to see how it pans out. Im not sure that its necessarily going to be better than simply using your controller - using gestures to access item DB would imo take longer than with the controller since you lift your hands from your controller, then make gesture and then pickup controller to play again = annoying imo. Likewise with the voice activated "grenade" throw. The reload option however, seems like a very good idea if executed well.

I was thinking about the reloads and grenade tosses via voice for multiplayer. A minor thing but I prefer to keep my thumbs on the sticks and fingers on the triggers as much as possible. I understand no one said this would be for multiplayer and I doubt they'd do it because of the long standing effort to not give advantages to certain players. But I wonder if it would be cool, I'd like to try it.

Sounds great can't wait for it to come out. (pops in Halo CE)

Like the sound of the scan option. That's neat and clever. Grenades not so much, but I'll give it a try to be sure.
