Brainstorming Design Ideas

Here is a cool design idea expressed through Wizard of Oz:

Adding on to this idea, we can have a screen on the controller which shows the scope of the gun when the user tilts it upwards, so the user can aim by looking at the controller screen instead of the big screen.

Other interesting ideas are:

1) slide finger on touchscreen to throw grenades (how fast you slide is how far you throw)

2) use a crank mechanism to imitate reloading a weapon

3) to melee (knife) an opponent, simply perform the hand motion with your controller

4) add vibration/force feedback to the triggers of the controller to increase realism

5) 3-mode switch (top-middle-bottom) naturally mapping to upright, crouch and lie-down; user knows their position without looking at small icon on screen by feeling the button's position without looking at it
