We have been busy finding out some top secret information on the NGP and  we have managed to find out a little more about how they plan to use  the camera in their launch window titles.
Our source close to Sony, who has seen the NGP in action already, gave  us some information on how the camera is used in the upcoming Uncharted  and Resistance titles for the NGP.
As a little quirk in Resistance players can pick up weapons that they  are looking at on the screen by passing their hand underneath the camera  on the outside of the NGP just as if they were picking up the weapon in  real life.
In Uncharted, when a light source is required, pointing the outside  camera at a nearby light or the sun will provide the necessary  illumination.
These are both interesting uses of the technology that in first party  titles that shows that Sony is keen for developers to make the most of  the technology available in the handset to provide a more immersive  experience.
Uncharted is due out with the NGP when it launches supposedly before  Christmas and Resistance is slated for sometime between January and  March 2012
