Top 10 SimpleOpenNI Projects for Kinect and Depth Cameras

1. Real-time Skeleton Tracking and Gesture Control

   • Build an app that tracks user skeleton joints and recognizes gestures (e.g., wave, push, swipe) to control on-screen elements or external devices.
   • Key components: joint smoothing, gesture templates, mapping gestures to commands.
   • Uses: games, interactive exhibits, hands-free controls.

2. Interactive Art Installation with Depth-Based Particle System

   • Generate particles that respond to users’ depth and movement—particles repel from close users and attract to distant ones.
   • Key components: depth thresholding, contour extraction, particle physics tuned for performance.
   • Uses: gallery installations, live performances.

3. 3D Point Cloud Capture and Visualization

   • Capture depth frames, convert to 3D point clouds, and visualize with color or height maps; include recording and playback.
   • Key components: coordinate mapping, downsampling, simple meshing or shader-based rendering.
   • Uses: 3D scanning, education, research prototyping.

4. Body Pose-Based Music/Sound Synthesizer

   • Map limb positions and gestures to musical parameters (pitch, volume, effects) to create a motion-controlled instrument.
   • Key components: smoothing, scale mapping, MIDI/OSC output.
   • Uses: live music, therapy, interactive performances.

5. Augmented Reality with Virtual Costumes and Masks

   • Overlay virtual hats, masks, or clothing onto tracked heads and faces using depth data for occlusion.
   • Key components: head tracking, simple face alignment, depth-based occlusion handling.
   • Uses: photo booths, entertainment apps.

6. Object Segmentation and Background Removal for Video Compositing

   • Use depth thresholds to segment people from background and composite them into different scenes or stream with transparent backgrounds.
   • Key components: depth filtering, morphological smoothing, edge blending.
   • Uses: streaming, virtual sets, presentations.

7. Interactive Fitness or Rehab Coach

   • Track poses and count repetitions, assess range of motion, and give visual feedback or scoring for exercises.
   • Key components: pose detection, repetition logic, simple accuracy metrics.
   • Uses: home fitness, physical therapy aids.

8. Multi-user Collaborative Sandbox

   • Let multiple users manipulate virtual objects projected onto a surface; interactions are based on hand position and gestures.
   • Key components: multi-user tracking, object physics, conflict resolution for simultaneous inputs.
   • Uses: education, collaborative playtables.

9. Depth-Based Heatmap and Crowd Analysis

   • Generate live heatmaps showing where people cluster and produce simple analytics (count, dwell time).
   • Key components: blob detection, tracking IDs, temporal smoothing.
   • Uses: UX studies, retail analytics, event monitoring (non-identifying).

10. Robot Navigation and Obstacle Detection Prototype

    • Use depth sensing to detect obstacles and build a basic SLAM-free navigation demo for small robots or mobile platforms.
    • Key components: depth-to-distance mapping, simple occupancy grid, reactive obstacle avoidance.
    • Uses: robotics demos, educational robotics.
