Capillary Refill using Augmented Reality

Abstract

The opportunities within augmented reality is growing. Augmented reality is a combination of the real and the virtual world in real time, and large companies like Microsoft and Google is now investing heavily in the technology. This thesis presents a solution for simulating a medical test called capillary refill, by using augmented reality. The simulation is performed with an augmented reality headset called HoloLens. The HoloLens will recognise a marker attached to an artificial hand. The marker is used to detect and keep tracking of the position and orientation of the hand. Then a virtual 3D hand will be rendered over the marker on the artificial hand. Inside the artificial hand there is a pressure sensor that will be used to detect when users are adding pressure to the index finger. The finger on the virtual 3D model will then change nail colour on user interaction, and thereby simulating capillary refill.
