Front and rear camera
Much like the Nintendo 3DS or any modern cellphone. The PlayStation Vita will feature both a front and back camera. Both cameras appear to be capable of recording video at 120 frames per second at a resolution of 320x240, and 60 frames per second at 640x480. The maximum resolution for both pictures and video appears to be 640x480.
Much like the Nintendo 3DS. The PlayStation Vita will be able to make use of augmented reality, this means that the back camera of the Vita can use objects in the world to make "living" 3D characters or objects from them. For now this has been mainly used in mini-games, but developers are experimenting to make it work in the high budget games aswell.
Dual analog sticks
Finally the handheld gamers can experience the full flexibility of having two analog sticks. This means tons of easier to use camera's in platformers, action and adventure games. But this could easily mean that we will finally see the big shooters with easy to use controls on a handheld. Also, the sticks are clickable just like the ones from the PS3- or Xbox-controller.
A modern portable like the Vita can't live without a nice touchscreen. the Vita is packing a 5-inch OLED screen, serving up bright, gorgeous colour. Touchscreen doesn't necessarily mean tons of mini-games like the DS had during its life. Sony is already integrating touch in his big budget games like Uncharted and LittleBigPlanet. Making players have new ways to play or new puzzles to solve.
Yes, not only does PlayStation Vita come with a normal touchscreen. It also brings a rear touchpad with it. It could seem silly at first that Sony would add this, but when you see games like Little Deviants in action or the opportunity to tap the back of your portable to activate a skill or to reload, you will think twice before turning your back on this.
You can't imagine buying a high tech handheld or cellphone anymore with motion sensing. Just like we know from the PlayStation 3 controller or an iPhone, the Vita will come with a Six-axis motion sensing system (three-axis gyroscope, three-axis accelerometer), Three-axis electronic compass. This will be used in games, but probably also on the internet or when you are checking pictures on your portable.
Near is a core PS Vita feature composed of location-based services, that utilize PlayStation Network. Near, developed specifically for this service and the network , will be pre-installed in the system to let users find out what their friends in the vicinity are playing now or what they were playing recently. Users can meet their friends and new players virtually, regardless of what games they are playing, simply by sharing their game information across different dimensions of time and distance.
Cross-game chat is coming to PlayStation Vita and this feature is officially called Party Chat. It will allow people to talk to each other through the PlayStation Vita system even while playing different games, using either a headset or the microphone built into the Vita device.
This is the new interface that will come with the PlayStation Vita. Every game title for PS Vita will be provided with a space called "LiveArea™" where users can share the fun and excitement with other players. Users will have access to the latest information of games provided from SCE and 3rd party developers and publishers through PlayStation Network. Additionally, PS Vita users will be able to view "Activity" log that is constantly updated with accomplishments from users who are playing the same game, which in turn can trigger active real-time communication among users.
This is developed specifically to guide every user about PS Vita’s brand new user interface such as the front touch display and the multi-touch pad on the rear, will come pre-installed. By playing “Welcome Park,” users can easily become accustomed to the three dimension-like finger motions used on PS Vita.
Last but not least, 3G is available exclusively for people who buy the 3G Vita model (wich costs 299$/€) This model will give you access to the internet at all times, providing you are subbed with a local cellphone or internet carrier. AT&T will be providing the 3G internet for the USA, wether you like it or not. Do not forget however that 3G internet comes with a subscription model that you will have to pay each month and if you really need to have internet at all times (before you go and order one).
