FPS added input

In real warfare, players are allowed to aim at something, but turn their heads to look at something else. Also, if a person wants to dual-wield weapons, he is able to aim them in two different directions. He is also able to yell at his team mates or enemy. This is technically feasible in FPS games, but the problem lies in controlling the second view and tracking facial expressions. I propose 2 technologies to be married to FPS games in order to bring these real-life options to the games.

The first technology allows the user to allow main player view to be oriented through the movement of the gamer's head. Triangulation of tracked points is used to constantly track the orientation of the user while he uses his mouse to orient his weapon. This allows for a more flexible playing field, as players are able to be firing in one direction, while looking in another. This technology (theoretically) doesn't need any additional hardware except for a webcam, although the use of glasses or other items/markings would allow for smoother tracking head orientation. The player's head would track on 3 axes, allowing for a tilting effect of the entire screen. The screen is not the only thing animated. The actual in-game player's head also turns with these turns, portraying actual head movements. This would improve realism of the game, as well as the game play. Another option for this (and this would take some getting used to, but going pro would mean something totally more awesome) is to allow for dual-wielding players to be firing in 2 different directions. Players could allow, with the touch of a button, their head view to stay with the main view, while they control the movement of their secondary weapon with their head.

The second technology tracks the facial expressions of players. As orientation can be tracked through the first technology, the technology will know exactly where your eyes, eyebrows and mouth are. The technology will then measure size and orientation of the your eyes, eyebrows and mouth to create a representation of these features in the game. Seeing the facial expressions that players portray will improve the realism of the game, being able to see players surprised as you frag them and being able to, non-verbally, portray your intentions to your teammates. Player mouth movements can them be coupled with VOIP programs to add another sense of realism.

Benefits: Added in-game realism, another gameplay dimension, better player collaboration/communication. Drawbacks: May take some time to get used to, it's all theoretical at this point. Additional hardware could give an edge to more dedicated players.
