Range of Motion Measurements Using Motion Capture Data and Augmented Reality Visualisation

Range of motion measurements are used by physicians, physical therapists and veterinarians. There is a need for a solution that would increase the accuracy and repeatability of the measurements obtained. Commonly used methods are based on tests using a classical goniometer are often inaccurate and depend on the individual interpretation of result by the therapist. The use of motion capture data to RoM measurements results in an accuracy of order of tens of micrometers, which is mainly due to the precision of the Motion Capture system. During the test, patient is not constrained by any device and has a total freedom of movement. It allows to carry out a medical examination not only during flexion and extension of the one limb but more limbs during dynamic movement such as walking. Clear visualization based on elements of the augmented reality in a simple manner presents measured angles, drawn on the image directly on the limbs of the patient.
