Movement Tracking in Augmented and Mixed Realities Impacting the User Activity in Medicine and Healthcare

The paper deals with the issue of comparing trajectories in augmented and mixed realities incorporated in medical and healthcare systems. The comparison process brings to a sequence of comparing pairs of elements of these trajectories. We match up pairs using either time-domain mapping or projection in Euclidean space. The suitability of matched up pairs are assessed based on gold standard Dynamic Time Wrapping method. Finally, we propose two similarity relations which incorporate the idea of coordination space and position vectors.
