Real-time
Meet the world’s most advanced body tracking software. Use our cross-platform SDK to build amazing motion capture apps in minutes. Powered by artificial intelligence. Created by humans.
Now supporting every desktop and mobile operating system.
Super accurate
Ultra light
Our system is based on advanced Artificial Intelligence and Machine Learning algorithms. The AI scientists of LightBuzz have cracked the code of skeleton tracking. The new SDK provides desktop-level performance on mobile devices. The best part? We never compromise accuracy. The software properly tracks the human body in 360 degrees of motion, even at the most challenging poses. As a result, our customers enjoy the same experience on a $2,000 PC and an $800 iPad. And, unlike similar systems, LightBuzz works with all major chipsets, including NVIDIA, AMD, Intel, Qualcomm, and Apple Silicon.
A vast family of cameras
Using your phone or laptop camera, you can access the 2D coordinates of each joint in real-time. If you have a depth camera, you also get the 3D coordinates in the physical space! You pick the camera that fit your needs. We do the rest.
Phone cameras
USB webcams
Apple LiDAR

Video files (mp4, avi, mov)
Intel RealSense
Azure Kinect
Structure Core
Luxonis OAK-D
FaceTime camera
Human-centered AI
Track up to 20 human bodies. Analyze the human movement in the frontal, sagittal, and transverse planes of motion.
Blazing fast
The higher the frame rate, the more responsive your apps will be. By default, you can get an astonishing 40-70 FPS performance in real-time on your phone, tablet, or laptop!
Our SDK records your sessions and stores the color, depth, and skeleton data. More specifically, it comes with a built-in video player that replays the videos using a familiar yet powerful user interface. Play, pause, change speed, and explore every angle of the captured motion.
Capture 60 FPS using the LiDAR camera or 90 FPS using the RealSense camera – and everything in between. Such smooth measurements are ideal for super-fast movements, like golf swings or baseball pitches.
Motion Analysis ready
Motion Analysis is complex. Building on years of expertise, our engineers have pumped the SDK with everything you need to analyze the human movement: angle calculations, planar rotations, bezier curves. All the Math you need – now accessed with a single line of code. Want more? The Enterprise version of our SDK comes packed with a virtual gym. It’s automatically analyzing dozens of movements while measuring the number of repetitions! The most popular fitness exercises are included.
Squats
Push-ups
Tricep extensions
Deadlifts
Shoulder presses
Lateral raises
Pull-ups
Bicep curls
Back rows
Jumping jacks
Lunges
+ 30 joint angles!
Customer support that cares
We love AI, but we hate bots. That’s why we never delegate customer service to automatic responders and canned emails. Instead, when you reach out to us, you interact with humans. Our support team is working side-by-side with our engineers to answer even your tougher questions; within one business day.
Simply put, the LightBuzz Body Tracking SDK allowed us to bring our vision to life. No need to worry about cameras or different tech stacks – LightBuzz has our back. Hands down, the best investment we made.
– James Kang, Grandmaster Fitness
After reaching out to support, within ONE DAY there was a new version of the asset that had fixed this issue and all was working great!
– Andrew Chlx
I use the LightBuzz motion tracking software tool in academic projects. The tool is excellent, very accurate, and simple to use. It does not require advanced knowledge, as it has several practical examples. In addition, LightBuzz support is great, responses are very quick and enlightening.
– Luiz Rogério Scudeletti, São Paulo State University
Super easy to use
There’s a reason developers love our SDK so much. Everything you need is accessible right out of the box. In addition, we provide a common API for all cameras. So, all you need to do is specify the camera you wish to use, and we’re taking care of the rest; no need to re-learn the API of each camera.
// Initialize a sensor
sensor = Sensor.Create(new SensorConfiguration
{
SensorType = SensorType.LiDAR,
Smoothing = 0.5f,
});
sensor?.Open();// Access color + depth + IMU + skeleton FrameData frame = sensor.Update(); byte[] color = frame.ColorData; ushort[] depth = frame.DepthData; IMU imu = frame.ImuData; List<Body> bodies = frame.BodyData;
// Pick the person you need Body closest = bodies?.Closest(); Body farthest = bodies?.Farthest(); Body left = bodies?.Left(); Body right = bodies?.Right(); // Or, select within a range List<Body> range = bodies?.InRange(1, 3);
// Calculate angles with 1 line of code!
Joint neck = body.Joints[JointType.Neck];
Joint pelvis = body.Joint[JointType.Pelvis];
float angle = Calculations.Rotation(
neck.Position3D, pelvis.Position3D,
Plane.Transverse);One SDK
to rule them all
We support all major desktop and mobile operating systems, hustle-free. Write once. Deploy everywhere.
The languages you speak
Power to the developers! LightBuzz supports your favorite tools and technologies. Unity is a first-class citizen, allowing you to reach every platform with a single code base. Of course, you can use C# and C++, too. Upon popular demand, .NET MAUI and Python wrappers are coming soon!
The cameras you need
By purchasing the LightBuzz SDK, you can use any camera you wish. LiDAR? Yes! Webcams? Sure! RealSense, Kinect, Structure, OAK-D? Of course! You can even analyze pre-recorded MP4, MOV, or AVI videos. All you have to do is select an input device, and our AI will do the rest.
Save time and money
You could spend tons of money and years of work training your own AI model – let alone hiring specialized scientists. You could tweak “free” solutions only to find out you can’t use them in your apps. Or, you could rest assured LightBuzz has your back.
Create awesome products in minutes
Got questions?
Yeap, our body-tracking software works with face masks, too!
Can I use it on unlimited projects?
Yes! You can use our SDK for an unlimited number of projects and installations — no matter whether you have a thousand or a million customers. The price remains the same.
Is technical support included?
Affirmative. Our dedicated support team is available within hours (or minutes!) of sending your support request. We provide first-class assistance on using the SDK and deploying your project. No bots. Only humans.
Do I need an Internet connection?
No, you don’t! Our SDK is running offline, so your customers do not need to have an active Internet connection. Moreover, you don’t need to activate the software on a per-customer or a per-device basis. The whole experience is smooth and seamless. All you need to do is ship great apps, and we’ll do the rest.
What input sources can I use?
On macOS, Windows, and Linux, we support ordinary USB webcams, RealSense, OAK-D, Structure Core, and Azure Kinect depth cameras. On iOS, we support the front and rear phone cameras and the new LiDAR depth camera. You may also analyze pre-recorded videos. Check the supported cameras.
What about other cameras?
We are always working towards supporting the best consumer cameras on the market. If you need a camera that is not part of the core body-tracking SDK, get in touch with us and we would be happy to add a custom integration for you.
What if a camera gets discontinued?
A considerable part of our offering is peace of mind. In 2017, Microsoft discontinued the XBOX Kinect sensor, and thousands of businesses remained without viable options. Not any more. Since we support the broadest range of manufacturers in the market, LightBuzz guarantees you’ll always use the latest commercial cameras.
What programming languages can I use?
Unity3D is a first-class citizen. Additionally, the SDK is available in C/C++, C#, and Swift. In case you need support for a different toolkit or technology, just let us know.
What if I don’t renew my license?
Well, we would be sad to see you go. If you decide not to renew your license, your customers will still be able to use your body-tracking apps with no interruptions at all. You won’t be able to deploy new ones.
Are you working on custom projects?
LightBuzz provides a broad set of services around body tracking, and we can help you with custom application development. Our diverse expertise covers desktop, mobile, and cloud technologies. If you have a project inquiry, contact us.
