  During the past summer, I worked at the Graphics Lab of UPenn and Penn Vet School came to use for help. They want us to build up a training application for them. We talked with them, and help them find what they exactly want to get: a horse bone surgery training, because Vet School students rarely have a chance to learn how to surgery on horse. With the accurate demands, we designed and developed the training application based on Microsoft Hololens Platform, using Unity Engine and C#. In order to make the bone appear at the correct position, we applied Vuforia image tracking SDK to recognize a marker sticking on real bone model and make digital bone model align with it. But the original SDK will cause the digital bone model jitter a lot, and we know that is unacceptable for medical use, so we want to make the digital bone show up accurately. Therefore, we digged into the Hololens APIs and find Spatial Mapping and world anchor system can help us anchor the bone. We added these feature in our App to eliminate jitter of image tracking and update the position and orientation of bone model periodically and smoothly. After the bone show up correctly, Vet School professors wanted us to add guiding features so students can see the fracture plane of bone and have some opaque cones representing the positions and orientations they should drill down. Also, they want the application to be interactive: be able to use a drill model to actually drill on the bone. It is a tough task, because it is hard to track the drill. But we figured it out by using Bluetooth sensor. It gets the orientation of drill and sends drill’s real-time orientation to Hololens through Photon Unity Networking system. Show less
