I think the Oculus Rift VR headset has really made big improvements in the VR space. One of the key things it has solved is motion blur which caused discomfort for users previously. They have a developers SDK and kit which I am tempted to run some tests with. I see some interesting applications for interactive storytelling and also training specific skills.

A very interesting presentation from Leah Buechley from MIT on paper based electronics using conductive ink. I believe this could be used in future packaging for smart notifications when products are running low.
