The week of Spring Break! No classes.
Starting off with GTA work, didn’t have to keep any office hours this week which was nice. However, a lot of grading came my way. Had to grade paper summaries and Assignment 2 for CS5590. Assignment 2 was an interesting one based on XSS attack. Had to grade Quiz 2 for CS1054 which took longer than I expected mainly because student submit code snippets as text in canvas quiz and their solutions can come in many forms. Dry running each of them and deciding how to grade unexpected errors took most of the time.
For coursework, although there were no classes, the homework for Machine Learning course was due right after spring break. The last few lectures were provided in form of asynchronous recordings that I caught up on during this week and then started on the homework. The homework itself involved a lot of long mathematical calculations so it took its sweet time being completed.
For research work, starting with the good news, I have been able to make Surf Share run completely with both HoloLens 2 and tested out its functionality and performance. I found out that it is capable of creating multiple virtual object out of the same real world object. A user can use the whit handle to change the height of the object making it shorter or taller. It also has audio support. However, there are some limitations. Firstly the portals need to be created on a solid background color and according to my distance the hue difference of the background and the object in question should be a lot to create virtual objects, it works on very bright objects. The 3D representation of the object is basically taking the top view of the real world object and extending it’s height, it can mainly represent complicated objects as blobs. The movement of portal is possible along X-Y axis only. However I believe we can edit the source code to enable Z-axis movement too. I have recorded a demo to present in Weekly Meeting. Understanding these limitations I have come with another potential task for the user study that plan to discuss in the Weekly Meeting. It is not a medical task per say but one can argue for how it can be representative.
