Narrative:

On the takeoff roll; after calling out 'thrust set'; I scanned the EICAS engine indications; and then I fixated on the altimeter confusing it for the airspeed indicator. When the numbers on the altimeter dial did not increase during the takeoff roll I mistakenly believed it was a stuck airspeed indication and called for an aborted takeoff. The captain aborted the takeoff and we taxied in to a location where we could talk to maintenance. As I was explaining to the captain what I had seen I realized my mistake; I had confused the altimeter indication for the airspeed. There were no problems with the aircraft and we completed the flight safely.
