Can you solve this Rubik's cube from inside of it?

You have woken up to find yourself trapped in what appears to be a giant Rubik’s cube. A Rubik’s Cage I suppose. Bewildered, you take a look around (better video on imgur or just click the photo).

Each of the individual cube faces seems to have a letter transcribed onto it from outside, although it is difficult to read from inside.

Glancing down, you find a tablet and a diagram by your feet:

It would seem you need to enter a single 9 letter word into the tablet to escape. Who knows what will happen if you get it wrong… Maybe solving the cube will help reveal the answer?

Here’s a better look at the sides of your cage (click for higher resolution):

Don’t get it wrong, there’s only one attempt remaining!
