[quote name='crunchewy']And in addition to that I suspect it doesn't really detect twisting motion of your wrists, which is important for realistic swings. I have not tried the demo, but nothing in Kinect so far has been able to detect that kind of subtlety. Wii Motion Plus and Move can.[/QUOTE]
golf (and tennis for that matter) do not have wrist motion.
Golf swing basics are:
Grip
Stance
Position at address
Weight distribution
Backswing
Swing plane
Follow through
Too strong a grip may cause you to roll over the shot at impact creating a draw or a hook spin on the ball at impact. Too weak a grip may cause you to leave the clubface open at impact inducing a fade or a slice.
After a proper grip, the next key to the best golf swing begins with your stance. You are going to want to position yourself so that your arms are comfortable and you are not reaching for the ball, nor so close to it that you feel all jammed-up.
Your weight distribution will also be a good indicator as to whether or not you have properly addressed the ball. If you feel that you have a lot of your weight on your toes, then you are reaching for the ball and you are therefore too far away from the ball with your stance. If you feel that you have a lot of weight on your heels then the opposite problem is true, you are too close to the ball.
The start of the golf swing begins with the backswing. The backswing should not be rushed under any circumstances. A fast backswing will almost always ruin the timing of the golf swing causing a lot of energy dissipation that will cause the ball to travel a shorter distance or to be errant in direction. The backswing will also establish the golf swing plane that is important for hitting the ball long and straight.
A very important aspect of the golf swing is often overlooked – and that is the importance of the follow through of the swing after striking the ball. Focusing on a good follow through will actually do wonders for improving the actual impact made when striking the ball. A solid golf swing will have a solid follow through, one in which the hips are turned, the stomach or belt buckle is facing the target, and the club head is allowed to continue to wind up behind your back. Failure to focus on a good follow through, or finish to the swing, will often cause the ball to squirt off the clubface in directions unintended.
The downswing is where you give your shot power. This does not mean that you should try to impart extra power with your shoulders, biceps or wrists. Instead, the power will come automatically due to the speed at which the head of your club is moving. In fact, if you try to flick your wrists, you will actually hamper this speed and ruin your shot. For a perfect golf swing, you should ensure that your wrists remain cocked, weight switched from your right foot to your left and that you are square on with the ball at the time of impact.
This is the disconnect problem between gamers and reality. Gamers reason out what they think is reality when it's not. That's why you can't emulate true sports in video games. For one thing, sports are really hard! So to expect someone to play tennis with real tennis strokes is not realistic because gamers expect results. We play video game tennis because we want a fantasy world where we're great at tennis. i actually play real tennis (USTA 4.0 rating). most of these gamers that talk about "realism" don't seem to know. it's like the 12 year old that swears Gran Turismo 5 is the most realistic thing ever. heck, there are people that incorrectly think the way you swing is the same between tennis, racquetball, and table tennis.
And to be honest, if they made it too realistic, most people would hate it. beginners already hate tennis when they first step on a court because it's really hard. balls are always launching over fences. or hitting the bottom of the net. people always misjudge correct location of their body relative to the ball. people tend to swing very late (you should already be swinging with the ball about 5-6 feet in front of you). people also tend to stand so stiffly when they swing and not have a big enough knee-bend (you're supposed to hit from below the ball and come up/forward as you transition your weight into the ball).
So for a motion game, you have to balance the expectations of a gamer with reality. You need to make the controls such that gamers are not getting quadruple bogeys every hole but yet still have some semblance that you have to have a proper swing.
Same thing with the dance games. You may practice and score "flawless" but does your dancing look like real dancing? Like the dancers in the commercials? Those are professional dancers and they make the moves look hot. But at home, it usually looks awful and stiff.
The developers for Puss in Boots talked about it (check out the Gamasutra article). "We wanted the player to feel heroic, and this raised the next problem. Puss always looks great because he is posed by some of the world's best animators. Most players, on the other, hand do not exhibit the same flair. This is further compounded by the player's egocentric bias -- the perception that they look considerably cooler than they actually do."
"We quickly discovered this when we first hooked up the sword fighting. We initially used avateering -- the process of mapping a player's exact skeletal movements on to the on-screen character model. Puss would do exactly what the player did, but this simply highlighted the gulf between the two. It felt underwhelming rather than heroic (not to mention the fact that the on-screen character ceased to look and behave like Puss at all)."
As for Tiger Woods 13, the developers say they're tracking your shoulder, arm, and body positions which is what really matters in golf, not your wrist. They also said that they're detecting whether your motion is smooth and that you're not rushing your shot. They addressed the spin motion by letting you affect the ball after it's in the air. If you watch a professional golfer, their swing is buttery smooth. There are no hiccups. They don't look like a blur. Swinging faster doesn't produce a better shot.
I'm not a great golfer. If I was, I would be on tour. Like they say, it's much easier knowing what you're supposed to do than actually doing it. Even the great golfers shank the ball a number of times. That's why they do thousands of strokes a day every day.
The Wii has messed up a lot of gamers logic because with the Wii, there is waggle. In Wii tennis, if you play with real strokes, you'll lose. You win by whipping with your wrist as fast as possible.
