Just finished up my newest creation: Usability Defender V.1.
The application is built in Processing and is a usability video game with the goal of teaching the user basic web usability (yeah it’s a little tongue-in-cheek). All the concepts are based on Jakob Nielsen’s past research and the game is sort of a Galaga/Centipede mash-up.
I did perform two usability tests on the portal with UserTesting.com; if you are interested in checking those out they are located here.
If you are looking for a more in-depth outline of the project you can access the research paper for it here.
P.S. Please excuse my nerdiness…
