The Ultimate Screen Golf Experience: How It Works

how does screen golf work

Golf simulators have been around since the 1970s, offering an indoor alternative to the traditional game. They allow players to practice and play golf inside on a digitally replicated golf course, using a combination of hardware and software. The hardware includes cameras, radars, optical sensors, hitting mats, projectors, impact screens, enclosures, nets, and sound systems. The software takes the measured parameters such as ball speed, club speed, clubface angle, club path, spin, vertical and horizontal launch angle, etc., and simulates the shot on a screen. The cost of a golf simulator can range from a few thousand dollars to tens of thousands, depending on the technology used and the room setup.

Golf simulator setup

Setting up a golf simulator at home can be a big investment, but it's a smart one if you do it right. The cost can range from a few thousand dollars to well over $20,000, but it's important to choose a setup that works well together.

First, decide on a budget and a setup type. The most expensive component of your indoor golf simulator setup will likely be the launch monitor. This is the engine of your simulator—it tracks the ball, powers your simulator software, and determines how realistic your numbers and ball flight feel. Choose a launch monitor that fits your goals, not just your budget. You can always upgrade later.

Next, consider the space you are setting up your golf simulator in. You'll need a room that is wide enough, deep enough, and tall enough to accommodate your golf swing, as well as the golf net and screen. Most golfers choose to build their DIY golf simulator in their basement, garage, or media room. If you're looking for something more portable and space-saving, consider a golf net or retractable screen.

After that, it's time to choose your accessory pieces. Golf mats, computers, projectors, and software are all essential components of your golf simulator setup. For the software, you can choose from options like GSPro ($250 annual fee) or TGC 2019 ($950 one-time fee).

Finally, don't forget about the enclosure. This is more than just a way to catch your ball—it completes the experience. From net-based setups to full blackout hitting bays, the enclosure can change both your budget and how immersive your simulator feels.

How data is captured

Golf simulators capture data through a variety of input devices and sensors. These include radars, light sensors, motion-detecting hardware, sonic sound systems, optical sensor arrays, and cameras.

Cameras are becoming the norm in golf simulation, with one, two, three, or four cameras continuously monitoring the play area. More advanced camera systems, like the one used by Screen Golf Inc., can provide highly accurate shot-tracking data. For example, the Zoom-In Indoor Driving Range system uses a 2000 FPS High-speed Camera Sensor.

Optical sensors are another important component of golf simulators. These sensors scan across the bay in both X and Y directions to capture the ball's XY coordinates at two different points in time. By comparing these two coordinates, the system can determine the vertical launch angle, ball path, and speed. However, this system requires hundreds of optical sensors and emitters, making it very expensive to construct.

Radars are also used to gather launch data, including trajectory, launch angle, speed, and direction. This data is then used to calculate additional factors such as spin, axis, and tilt. Radars emit microwaves that reflect off moving objects, allowing them to track the movement of the ball.

In addition to these input devices and sensors, golf simulators also utilise launch monitors, which are considered the "engine" of the simulator. Launch monitors track the ball, power the simulator software, and determine the realism of the numbers and ball flight. They play a crucial role in simulating the entire flight of the ball from beginning to end in real-time.

Data processing

Golf simulators are equipped with hardware such as cameras, radars, optical sensors, projectors, displays, hitting mats, and nets. They also consist of software that takes the measured parameters such as ball speed, club speed, spin, launch angle, and so on.

The launch monitor's radar or laser technology collects data about the ball's flight and club head, which is then sent to the computer. This data includes information on launch angle, spin rate, ball speed, carry distance, and more. Advanced sensors can also track club head data such as club speed, club path, and clubface angle.

The data collected by the launch monitor is then sent to the computer, which processes it with the help of simulation software. This software calculates ball flight using a variety of algorithms, taking into account factors like wind speed and direction, as well as the terrain of the virtual environment. The software then determines where the ball should land, and this data is then projected in numeric form along with the visual on the screen.

Photometric sensors in a golf simulator use light to measure the performance of golf shots. These sensors are placed around the impact screen or projection surface and detect how much light reflects off the ball at different points during its flight. The data collected by the sensors is then processed to create a realistic simulation of the ball's flight, taking into account factors such as spin rate, launch angle, and speed.

Data analysis

One of the primary advantages of screen golf simulators is the ability to record and analyse data for each shot, providing immediate feedback on a range of parameters. These typically include club path, clubhead speed, club impact location, ball direction, launch angle, ball speed, smash factor, spin rates, total shot distance, and trajectory. This comprehensive data analysis allows golfers to identify areas of weakness and track their progress over time.

Advanced simulators often come with their own software, which uses environmental sensors to track each shot. The software captures the entire shot, from the impact of the clubface to the bounce of the ball, providing golfers with a detailed analysis of the ball's flight path. This data is then utilised to simulate the shot in a virtual environment, offering a realistic representation of the ball's trajectory, speed, and other factors.

Launch monitors, such as GOLFZON's Wave, play a significant role in data analysis for screen golf. The Wave can analyse 34 data points, including unique data points for putting. This in-depth analysis helps golfers identify areas requiring improvement, make informed equipment choices, and improve their accuracy and consistency.

Additionally, data analysis in screen golf extends beyond individual shots. By collecting data over multiple rounds, golfers can identify patterns and trends in their performance, developing strategies to improve their overall game. This long-term data analysis can be particularly useful for golfers who want to fine-tune their skills and lower their scores.

Instructors and coaches also utilise data analysis in screen golf to enhance their teaching methods. By reviewing a golfer's swing data, instructors can tailor their sessions to address specific areas of improvement, ensuring a more effective learning experience for their students.
