A major difference between the NGP and 3DS lies in the two devices' touch-sensitive technologies. The 3DS will reuse the original DS' resistive touch screen, whereas the NGP will have two capacitive touch areas (front and rear), of the type most tablets and smartphones use today (including the iPhone and iPad).
The 3DS' resistive touch screen requires some depression (hence the stylus), but can also respond to a finger press. The technology offers a nice level of precision (like when handwriting or pecking at small virtual keys), but certainly requires a bit of a learning curve when being used in tandem with a stylus.
With the introduction of the NGP's front and rear touch capabilities, players will essentially have another dimension of interaction at their disposal. At first glance the rear pad might seem silly, but after the insightful video to the right, we're beginning to think it might actually provide a more seamless gaming experience. The video showcases a game called Little Deviants, in which the player drags a finger across the rear panel to manipulate the world onscreen. We're excited to see that for the first time gamers can interact with a portable gaming device without their fingers blocking the screen.… Read more
