yes keep hitting RT and LT on the xbox to get out. Achievement Unlocked.
There is also a Computer at the corner of the room, If you use it , it should say ask you for a code to unlock some of the maps for Zombies
press L2 and R2 rapidly
If you are talking about the computer after you get out of the chair, it is DOA. This unlocks all the new Zombies maps.
First of all,(for black ops) To get out of your chair rapidly tap LT and RT or the 2 PS3 triggers (if you have a PS3). When you get out of the chair, turn around and you should see a computer at the corner
get up from the chair in the menu, go to the computer and type in DOA
You break out of the chair in the main menu by looking at your hands and alternating the triggers. then walk around the chair to the computer and type in DOA.
you press r1 r2 at diffrent times then get out of the chair and go to the computer and press on it.
You go to the computer behind the chair and type in codes. If you type in "help" it gives you some codes and if you type in "zork" it gives you an achievment.
You can not get out of the chair. It is part of the game that you dont play. You just watch.
For xbox you repeatedly tap x
When you are in the chair tap lt,rt, really fast and you can get out of the chair
