Edge-Based Classes
Teachers select materials, record reference motions, launch classes, and manage assessment from the large-screen edge terminal.
AI 3D Movement Teaching Platform
AI MovementTeaching, Measured.
Lingdong combines multi-camera 3D pose, edge AI, and assessment reports to turn movement teaching into system-level understanding.

Start With One Class
One system connecting teachers, students, and institutions.
This is not another video tool. It connects motion capture, reference movements, class assessment, lesson review, and growth records into a sustainable teaching data loop.
Student Review
Schedules, learning history, scores, and skeleton replay are presented together so students understand their score and progress.
AI Reports
Overall scores, radar dimensions, motion curves, highlight clips, and coach feedback become shareable learning outcomes.
Institutional Assets
Reference materials, class records, and student growth profiles accumulate into reusable, manageable, and scalable teaching assets.
Smart Edge Teaching
Put intelligent computing in the classroom, not behind cloud latency.
The edge terminal handles capture, control, assessment, and local processing, meeting real classroom needs for low latency, stability, and privacy.
- ✓Reference motion recording
Teacher demonstrations become structured reference assets for comparison and reuse. - ✓Synchronized multi-camera capture
Class footage, main-view video, and skeleton data are archived together for later review. - ✓Data generated during class
Each class becomes part of the institution's digital teaching system, not just a one-time offline session.
Core Technology
Multi-camera 3D pose estimation, supporting up to 24 people in one space.
With synchronized multi-view capture, cross-view identity matching, 3D reconstruction, and skeleton tracking, the system continuously understands each learner's movement path.
Multi-View Capture
3D Reconstruction
Multi-Person Tracking
Real-Time Tracking
Occlusion Robustness
1. Capture
Multiple cameras cover the training space and reduce single-view occlusion and angle errors.
2. Reconstruct
Multi-view skeleton cues are fused into one space to form analyzable 3D poses.
3. Analyze
Rhythm, stability, coordination, and completion are evaluated as structured dimensions.
Post-Class AI Assessment
Beyond the score, into the movement.
Lingdong turns each score into dimensions, curves, clips, and skeleton replay so coaching is faster and review is clearer.
- ✓Explainable scoring
Scores plus radar dimensions locate strengths and gaps quickly. - ✓Reviewable process
Main-view clips and skeleton replay make feedback visible. - ✓Shareable outcomes
Reports support parent communication, renewals, and brand display.
Product Story
The value of a class extends beyond its 60 minutes.
Lingdong connects pre-class materials, in-class movements, post-class reports, and long-term growth systems into a sustainable operating loop.
01Before Class
Reference materials, course settings, and training goals are clarified.
Reference materials, course settings, and training goals are clarified.
02During Class
Multi-camera capture, real-time tracking, and edge-based class control.
Multi-camera capture, real-time tracking, and edge-based class control.
03After Class
AI reports, video review, coach feedback, and growth records are retained.
AI reports, video review, coach feedback, and growth records are retained.
Student Growth Loop
Keep growth visible after every class.
Learning time, lesson records, score changes, badges, certificates, and levels make progress cumulative and motivating.
- ✓Progress
Turn "I took a class" into "I am improving." - ✓Professionalism
Use data and visual outcomes to show course value. - ✓Retention
Build long-term learner assets beyond one session.
Real Mobile Experience
The student app is not a backend extension; it is a window into progress.
Dashboards, course history, AI reports, and personal growth are designed as a lightweight, clear, repeatable learning entry point.
Deployment and Operations
From a single-classroom pilot to standardized multi-site rollout.
01 Site SetupCameras, edge terminals, and large screens are installed and calibrated for full coverage.
02 Material BuildingRecord teacher reference motions to build reusable institutional material libraries.
03 Class OperationTeachers choose materials by course while the system records video, skeleton, and scoring data.
04 Report GenerationAI generates assessment results, review materials, and smart comments for the student app.
05 Long-Term OperationLearning profiles, level systems, and proof of progress support renewals, referrals, and brand display.
For Teachers
Reduce repetitive recording and explanation so teachers can focus on guidance, class organization, and personalized feedback.
For Students
Move from "my teacher said I did okay" to "I can see my movement gaps, score changes, and next steps."
For Institutions
Turn teaching materials, classes, learners, and assessment data into visible, shareable, scalable brand assets.
Make every movement session visible.
Lingdong uses AI to understand movement, data to connect teaching, and review to drive growth. Built for dance, sports training, school arts education, and rehabilitation training.
