I talked to my class yesterday about this project of making it easier to learn how to visualize things in four dimensions.
We went over the principle of the 4D virtual trackball, then everybody got to try out the Oculus Rift, to experience for themselves what an immersive graphical world is like.
Even before we demo’d the Oculus Rift, I asked the class how many of them would be interested in exploring the fourth dimension. A lot of hands went up.
I consider this a very good sign.
