Real-time motion tracking for iOS, Windows & Linux

LightBuzz Logo Outline

The future of body tracking

It’s been over ten years since Microsoft introduced the Kinect for markerless body tracking. Since then, the world has gone mobile. Today, smartphones feature powerful cameras, while depth perception is already available for the desktop. Using modern AI and advanced Maths, LightBuzz brings the most accurate business-ready skeleton tracking on the planet.

2D & 3D tracking

The LightBuzz Body Tracking software allows you to track up to 20 human bodies with 21 joints each. Using any RGB camera, such as your phone or laptop camera, you can access the 2D coordinates of every joint in real-time. Does your device have a depth camera, too? Great! In that case, you also get the 3D coordinates in the physical space! This way, you can analyze the human movement in the frontal, sagittal, and transverse planes of motion. On iOS, we support the new LiDAR sensor. On Windows, we support the Intel RealSense camera series.

Fast. Accurate. Lightweight.

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 toughest poses. Our customers enjoy the same experience on a $2,000 PC and an $800 iPad.

Record at 60 or 90 FPS!

By default, you can get an astonishing 40 FPS performance in real-time on your phone or laptop! But you want more. Our built-in video recorder allows you to record 60 FPS using the iOS LiDAR camera or 90 FPS using the RealSense camera. This way, you’ll get incredibly smooth measurements that are ideal for super-fast movements, such as golf swings or baseball pitches.

LightBuzz allows you to record your body-tracking sessions and store the color, depth, and skeleton data. Our Unity package also comes with a cutting-edge video player that replays the videos using a familiar yet powerful user interface.

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 Maths you need – now accessed with a single line of code.

Want even 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 Deadlifts Pull-ups Push-ups
Shoulder presses Bicep curls Tricep extensions Lateral raises
Jumping jacks Back rows Lunges + 30 joint angles!

Premium customer support

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.

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.

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 take care of the rest—no need to re-learn the API of each camera. With LigthBuzz, you write once and deploy everywhere.

// Initialize a sensor
sensor = Sensor.Create(new SensorConfiguration
{
    SensorType = SensorType.LiDAR,
    Smoothing = 0.2f,
});
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

By purchasing the LightBuzz SDK, you can use any camera you wish. LiDAR? Yes! Webcams? Sure! RealSense, Kinect? 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.

You've got questions?
We've got answers!

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 of sending your support request. We provide first-class assistance on using the SDK and deploying your project. No bots. Only humans.

What cameras can I use?

On Windows and Linux, we support ordinary webcams, RealSense, OAK-D, 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.

Are you planning to support Android and macOS?

Absolutely! Our team is currently working on the macOS and Android builds of our SDK. You’ll receive the new SDK as a free software update when ready!

What about other cameras?

Out of the box, our SDK supports webcams, iOS LiDAR, Structure Core, OAK-D, Azure Kinect, and Intel RealSense. If you need a camera that is not part of the core body-tracking SDK, let us know and we would be happy to add a custom integration for you.

What programming languages can I use?

Unity3D is a first-class citizen. Additionally, the SDK is available in C++ & C# on Windows and Swift on iOS. In case you need support for a different toolkit or technology, just let us know.

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 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.
