OrthoHandMotion
iOS Universel / Forme et santé
OrthoHand Motion visualizes hand movement in real time using camera-based skeletal tracking directly on your iPhone or iPad. The application reconstructs a digital skeletal model of the hand and performs approximately 140 real-time measurements, within a comprehensive framework of up to 179 algorithm-derived calculations, covering joint kinematics, spatial relationships, coordination patterns, and movement quality.
Core measurements include finger joint angles (MCP, PIP, DIP), thumb motion (MCP, IP, opposition), finger spread and inter-digit relationships, grip aperture, pinch distance, and cascade alignment. Additional dynamic metrics include range of motion, angular velocity, acceleration profiles, motion timing, repetition rate, and movement consistency. The system also estimates symmetry between movements and provides motion quality indicators such as smoothness, coordination, and variability.
OrthoHand Motion is designed to function entirely using the device camera, without requiring external sensors, markers, or wearable hardware. This allows immediate accessibility while maintaining real-time performance and continuous feedback. Measurements are derived from visual tracking and represent estimated biomechanical parameters based on detected landmarks.
The application includes multiple modes to adapt to different levels of analysis. Basic mode provides core motion visualization metrics. Advanced modes enable extended analytics, including temporal and coordination measurements. Research-oriented functionality allows recording of motion sessions and export of time-series datasets, including timestamped values for further analysis.
Guided recording workflows provide structured motion tasks, helping users perform repeatable movement sequences. These guided protocols support consistent data capture and enable comparison between sessions. Recording and playback features allow users to review motion and observe changes over time.
OrthoHand Motion on iPhone and iPad is designed for education, biomechanics exploration, gesture analysis, XR interaction development, and research workflows. It provides an intuitive way to understand how the hand moves, how fingers coordinate, and how motion patterns change during tasks.
The system emphasizes visualization and interpretability rather than precision measurement. All outputs are generated through algorithmic estimation models and may vary depending on environmental conditions such as lighting, occlusion, camera angle, and tracking stability. Accuracy may also depend on hand visibility and positioning relative to the camera.
All processing occurs locally on the device. The application does not require external data transmission, does not collect personal information, and does not rely on cloud-based processing for motion estimation.
OrthoHand Motion is intended for visualization, education, and research purposes only. It does not provide medical diagnosis, treatment recommendations, or clinical decision support. All measurements should be interpreted as estimations and not as definitive biomechanical or clinical values.
