CorectiAR

CorectiAR is an augmented-reality 3D registration, alignment, measurement and osteotomy-visualization tool for qualified healthcare professionals, researchers and trained adult users.

The Android workflow preserves the structured 63-capture registration sequence and five 4 × 4 cm references: RED femur, GREEN proximal tibia, BLUE distal tibia, MAGENTA calibrated pointer and ORANGE saw adaptor.

REGISTER IN 3D
Calibrate the pointer tip in X/Y/Z, track the required reference and register landmarks by on-screen command, camera-view tap or hardware volume controls. Dynamic segment references let registered geometry follow its marker; FROZEN mode snapshots current world positions.

LIVE 3D GEOMETRY
As registration progresses, CorectiAR reconstructs landmarks, mechanical/anatomical axes, transparent reference planes and staged measurements. Completed three-sample landmarks receive labels next to their projected 3D positions. Translucent planes preserve visibility of the camera, tracked references and geometry.

FLOATING LIQUID-CRYSTAL WORKSPACE
Command, tracking, next-point guidance, measurements, tools, model controls and registration are independent translucent floating windows. Drag by the title bar, collapse long content, hide panels, and recover them from the permanent Window Dock. Positions are stored locally.

STL / USDZ IN AR
Load STL or compatible USDZ meshes through Android's document picker. STL coordinates are interpreted as millimetres by default because STL has no unit metadata. Text-USDA/USD geometry inside USDZ is triangulated in-app and respects metersPerUnit when present. Place a model at the calibrated pointer tip, scale it in real time, or show/hide it without changing registered anatomy.

PLANNING / GUIDANCE VISUALIZATION
After the required stages, the app can display Fujisawa planning geometry, deterministic osteotomy correction around the registered hinge axis, and ORANGE saw-adaptor reference planes with alignment feedback from the CorectiAR workflow.

EXPORTS
User-initiated controls can export the five reference images, save a screenshot, and write registered coordinates and calculated measurements to CSV. Registration/model processing is designed to remain on-device.

DEVICE REQUIREMENTS
CorectiAR requires an ARCore-compatible Android device, camera and current Google Play Services for AR. It is AR Required. Accurate use also requires correctly printed 4 cm references and a calibrated physical pointer. Imported-model dimensions and placement must be independently verified.

PRIVACY
No Orthopractis account is required. Registration points, geometry, imported models and user-created exports are handled locally unless the user chooses to move/share exported files. Google Play Services for AR (ARCore) has separate data-processing practices described in the Privacy Policy.

IMPORTANT HEALTH DISCLAIMER
CorectiAR is not a medical device and does not diagnose, treat, cure or prevent any medical condition it only for education . It must not be used as the sole basis for diagnosis, treatment, surgical indication, implant positioning, osteotomy correction or intraoperative navigation. Qualified professionals must independently verify tracking, calibration, landmarks, calculations and displayed guidance. Patients and non-professional users should consult a qualified healthcare professional for medical advice, diagnosis or treatment.Privacy Policy: https://www.orthopractis.com/privacy
