In Portal, the player controls the protagonist, Chell, from a first person perspective as she is challenged to navigate through a series of rooms using the Aperture Science Handheld Portal Device ("portal gun" or "ASHPD"). The portal gun can create two distinct portal ends, orange and blue. The portals create a visual and physical connection between two different locations in three-dimensional space. Neither end is specifically an entrance or exit; all objects that travel through one portal will exit through the other. An important aspect of the game's physics is "momentum redirection." As moving objects pass through portals, they come through the exit portal at the same direction as the exit portal is facing. This makes it possible to jump through the portal and emerge moving in a different direction across the room.[9] For example, a common maneuver is to jump down to a portal on the floor and emerge through a wall, flying over a gap or another obstacle (see illustration). This allows the player to launch objects or Chell herself over great distances, both vertically and horizontally, referred to as "flinging" by Valve. As GLaDOS puts it, "In layman's terms: speedy thing goes in, speedy thing comes out." If portal ends are not on parallel planes, the character passing through is reoriented to be upright with respect to gravity after leaving a portal end.
