The popularity of Iron Man, and the trend in wearable tech meant that something like this was going to come along sooner or later. One of these masks aids hearing, and allows the wearer to isolate individual sounds clearly amongst many others. It would help you hear one person standing far away in a crowd for example. The second mask enhances sight, and uses a video camera and two video screens (one for each eye) to display an filtered or altered version of whatever the wearer is looking at. One example of the filters used is to give moving objects a kind of ghost trail – an application of this could be to analyse sports people’s movements and techniques on the pitch. Thankfully they have made them look pretty awesome as well!
