My two cents… I own about 6 or 7 Kinect games now, and I would like a unified gesture structure between game manufactures. An example of this would be how pausing a game by holding your left arm at a 45 degree angle works for most games, so it would seem like a novel idea to have a standard library of different gestures across game vendors.
Additionally, it seems to me that there has to be a better way for games that require you to raise your hand above your head before proceeding to accomplish this gesture. Facial recognition seems to be the best answer but even a voice command would be better???
On the pros side of the table, the interface works great and seems to recognize the player's movement brilliantly. Play Kinect Sports and check that out… bowling is a very good example. Picking an exact board can be a little touchy, but the actual bowling technique is dead on.
Can't wait for more games to come down to market. I see huge opportunities for game companies in this arena.
