I've heard a lot of people here wonder about how Natal could control various games, and come up with some solutions. For your viewing pleasure, I will NOT be using green right now. Before I start tough, the tech was supposed to be able to recognize detail from the player down to the size of a pinch.
Oh, but before I start...has anyone thought that maybe the game will let us CALIBRATE each action with our OWN gesture ideas? Now then...
FPS and Shooters:
Shoot: Either point your hand like a gun and bend down your thumb or use a periph with a trigger.
Duck: Bend your knees.
Jump: Go on the balls of your feet and down.
Cover: Same as crouch
Grenade: gesture that you are throwing an object
Reload: Take your other hand and pretend like your loading a clip into a pistol.
Extra Options: Up to the user.
Moving: Sorry, your gonna need an analog stick for this. The only possible way I can see to move Forward/back is to lean in and out, but obviously thats awfully annoying, limited and turning would be absolutely horrid.
Fighting games:
Set the camera to your side instead of in front of you, and then gesture the basic movements. For special attacks, gesture in the correct order or at the certain time. Duck, Jump, same with FPS.
Sports games:
Do I really need to explain this? Noooope.
Party Games:
See Sports Games.
RPGS:
Now this could be tricky, since RPGs are so varied. Obviously for games like Fallout and Oblivion, you'd use standard FPS control. Mass Effect the same. JRPGs would be much more difficult to figure, so I'd say various hand gestures for selecting options for turnbased ones, then similar fighting styles for the action JRPGs. Magic could be cast with certain "wand" gestures.
Well, that was all of the the of my head.
Green Initiated.
So, what kind of gestures would you want in your game types?
