Some Business Ideas with HoloLens – (20) Holo-Golf Swing

 

This is the 20th in a series of “Some Business Ideas with HoloLens”. Read other posts here.

I have been a golf fan since the late 90s, but I have never seriously played. With the help of professionals, I think I am good enough to write an amazing app for it, and make a lot of money with it. No, I will just give out the ideas, and let others write an amazing app and make a lot of money. Read on to find out if I am joking.

There are two key elements in golf: driving and putting. Putting is not something you can improve dramatically with proper training. It’s kind of grinding, sensing and you get the feel of it down the road. Swing is something more methodical, technical. The way you do it can be changed, and makes big difference to your game. This is common no matter if you are a beginner, a pro or Tiger Woods. I have been watching Tiger Woods’ game for almost 20 years now. He had got his swing right early, but lost it about 10 years ago, never get it back. I think one lesson we have learned is: don’t change your swing until it is wrong. Shooting a little ball a mile away, with that kind of speed and it has to be straight, margin of error is too small.

Can HoloLens help Tiger Woods get his swing back? I am positive.

What a swing coach can do to a player is to tell you: which muscle is used as main driving force, which part of your body need to move in which direction, which part is not supposed to move at all. It’s like building a 4D sculpture. The problem is he can’t execute for you, and there is no accurate measurement to guide you in real time. If there is, it can do nothing to you within half a second. I have been thinking if someone builds a robot golfer, it would be unbeatable, because it can swing perfectly, and therefore always put the ball within 10 feet off the hole for an eagle. When the golfer is wearing a HoloLens, it’s possible that we can train the golfer to something close to a robotic swing, therefore being perfect every time.

I am not talking about wearing it in the game, which the PGA would ban entirely, I am talking about using it in the training. Here is how.

When the player is wearing the HoloLens, the app can detect his position in the course and the position of the ball. The player’s physical figure can be input before hand. The target distance can be set before hand too. With a flip of finger, a hologram of the driver’s moving trajectory is shown, including force applied along the way. It all leaves the player to follow that line, if you can follow the line in both the trajectory and the speed, you will land the ball to the target. Of course there is a wind factor, and a spinning factor need to be input too. Following the trajectory is easier, speed is hard, but it give you a chance to do the best you can potentially do. You just keep doing that day after day, until you get the reliable muscle memories. It is more like tracing in the letters in hand writing. I did that when I was young, and I did get a good handwriting.

For pros like Tiger Woods, their swings are close to perfection, so it’s a matter of finding a couple defects in their swings. Or forget about the techniques, if you can follow the hologram in perfection, you have a perfect swing. The theories are less important than results.

So, what if you can’t follow the hologram in perfection? If only thing you do is tracing the trajectory with the driver, then that’s easy. Everyone can do that. Hard thing to do is getting to the speed, and still follow the trajectory. This leaves some work for the coach. The coach can use a few other HoloLens around the player, and capture the action in 3D, so they can sit down watch the 3D holographic replay in slow motion to figure out what went wrong.

The development effort in generating the holographic trajectory is not hard, I believe some people already figured that out for us. Writing an app with basic features can be straightforward. But imagine how much money you can make with that: from Tiger Woods alone.

    A GPS-driven overlay would be brilliant. Imagine seeing the hazards, distances, etc. all overlaid on the course as you look at it. A scorecard and scores, perhaps. I’d definitely buy this if the price was sensible. Works as sunglasses too!

    • Sean Leith

      Absolutely. The things you said are there. HoloLens can acquire live information from the clubhouse through WiFi. I think GPS sensor very likely already there. Also I find putting is interesting too. I am going to post another one for the putting later.

      An augmented reality GPS sounds great – be something the golf authorities should start considering soon. GPS info is legal now – but not wind/weather info, and what about contour information – be an interesting debate!

    “Putting is not something you can improve dramatically with proper training.”

    Seriously? Good coaching can take an ape and make a an entirely competent putter. In a week. It’s all about the “proper training.”

    As for the rest, the physics engine alone is a major development project and requires an expert level understanding of swing and ball flight mechanics. The GPS stuff is easy, by comparison.
