Question about Master Chief's armor.

In this video about the upcoming special Xbox One console for Halo 5 they also talk about the limited edition Master Chief controller. At around 2:35 into the video the lady mentions they put Master Chief’s Braille marking on the back of the controller. Does anybody know what it means?

If its the same has his halo 4 braille, its just 117.

It is to assist blind gamers.
