Comparison between the Kinect™ V1 and Kinect™ V2 for respiratory motion tracking

Abstract

In this paper, we aim to assess the accuracy as well as compare between the Microsoft Kinect™ version 1 and Microsoft Kinect™ version 2 with regards to the purpose of respiratory motion tracking. We find that both correlate well to an alternative method of respiratory motion measurement i.e. a respiratory belt, up to a distance of around 2 m. However, we find that the Kinect™ version 2 has a slightly higher correlation, which can be explained by it being a newer device, as well as having a slightly higher cost.
