AI will map 21 hand keypoints and track poses. 100% Local.
Hand-Mesh v3.0Kinematic-Symmetry
Private Finger Tracking
The Future of Interaction
Our Hand Tracking AI represents a leap in browser-side computer vision. By identifying 21 unique points of interest (landmarks) on a human hand—including the wrist and four joints per finger—we can reconstruct the hand's geometry in 3D space with sub-centimeter precision.
Powered by MediaPipe Hands technology, this tool is the foundation for touchless interfaces, sign language interpretation, and gesture-controlled applications. All coordinates are calculated locally in your browser's RAM, ensuring your biometric movements are never recorded or shared.
Technical Features
- 21-Joint Tracking: Maps the entire skeleton of the hand for precise gesture analysis.
- Real-time 3D Estimation: Calculates X, Y, and Z coordinates for every fingertip and joint.
- Zero Latency Processing: Runs using WebGL acceleration, eliminating the need for server round-trips.
- Privacy Centric: No camera feed or biometric mapping data is ever sent to the cloud.
Quick Start
- Upload a photo displaying one or both hands clearly.
- Wait for the "AI Ready" status indicator.
- Click "Track Gestures" to analyze the image.
- See the 3D map overlaid on your hand in the result view.
Frequently Asked Questions
AI Hand Gesture Tracking (Hand Mesh) is a computer vision technique that detects and tracks the positions of hands and fingers, identifying keypoints like knuckles and fingertips to understand hand poses and movements.
Our engine uses the MediaPipe Hands model, which tracks 21 unique 3D coordinates for each hand—including the wrist and four points for each finger—providing high-precision gesture data.
Yes. In the HiFi Toolkit, all hand tracking happens 100% locally in your browser. We never capture, store, or transmit your hand images or biometric data to any server, ensuring complete privacy.
Hand tracking is used for touchless interfaces, sign language recognition, virtual try-ons (rings, watches), driver distraction monitoring, and human-computer interaction (HCI) research.
Yes, our advanced Hand-Mesh engine is capable of tracking multi-hand scenarios, detecting complex interactions and bilateral gestures with minimal latency.
