While being a grad student at WPI, I worked on a research project in UXDM lab at WPI school of business, for making an eye-tracking-enabled game package. This pack included 2 eyes-controlled mini games, using Tobii eye tracking systems, and more games were decided to be created. The purpose of the game pack, mainly, was finding the best usability for eye tracking in HCI.
I used Microsoft WPF technology to create the GUI and games.
Here are a few screenshots of what I created.
