The researchers have now developed an astounding head tracking and 3D effect technology available on iPad 2 and iPhone 4 and this works without any need of 3D glasses. The 3D view is totally different and enables these iOS devices with real time 3D experience.
The head tracking is a technology which makes normal 2D images to give us a 3 dimensional effect, but this 3D effect only works for only one person at one time, the practical application of this 3D view looks like as you are entering a real room when you look at the frame or display of these devices and moving your head around you can look the objects from different directions, the more closer you get to the screen, the object look more nearer, this 3D view actually provides the illusion as if the objects are floating and vagrant on the screen. The head tracking science makes the iPhone frame work like as you are looking through a real time window, that is when you move to left, you see more of right side and vice versa, and when you move closer, you cover maximum area on both left and right side. With this device the 3D experience is very much realistic and synergetic than other 2D devices.
