Hubble Needs Glasses is a computer lesson that teaches basic optics concepts using gesture interactions.  The system was used as the experimental testbed to test whether gesture-based interactions increase instructional efficiency in a computer lesson. 

My role:  Principal Investigator
- Designed, conducted, and analyzed (Regression) a series of experiments to test the instructional efficiency of gesture-based interactions as well as the medium of instruction on a computer-based science lesson
- Developed instructional content on optics concepts and wireframed (designed) the lesson for programmers to implement
- Conducted a series of studies to develop validated natural gesture-based interactions that were perceived as natural by users
- Managed a team of computer engineers to program over 30 gesture-based commands (Unity game engine) that could be recognized by the Microsoft Kinect motion-tracker and performed extensive bug testing of the computer system
