Headset

Primary Mode: The communication device seems to be a bluetooth earpiece in the right ear, with two buttons. The first button is for calls, the second for secondary mode.

Secondary Mode: If the second button is pressed, the bluetooth does a seemingly impossible shift, metal sliding from it, around the head, to the other ear. Both ears become covered in something much like a set of headphones, while from the right,metal slides to produce a microphone like a gamer's headset. A hologram of a keyboard appears in front of the wearer, and with the right set of gloves, one can produce up to five holograms of windows by opening their palm, as well as type.
