The purpose of this project was to develop a system to monitor a classroom of per-kindergarten children and track behaviors that are indicative of developmental disorders such as autism. To do this, multiple Microsoft Kinect sensors were set up around an open floor plan, pre-kindergarten classroom. There was a lot of overlap in the views, which did cause interference in the sensors, but children moving through the scene could be extracted quite cleanly in each of the sensors.
I worked with grad students Josh Fasching and Nick Walczak and primarily helped determine the cause and severity of depth inaccuracies with the Kinect sensors. I also helped improve the calibration process used when setting up the system.
The overall project worked out pretty well, with collaborators from Computer Science to Psychology to Childhood Development getting a lot out of it.
