The PlayStation 4 will have a new PlayStation Eye camera available alongside it at launch. Sony hasn't really advertised it much outside of the PlayStation 4 reveal in February though. During E3, however, it did create a small video to show off some of the cool things it has planned for the new PlayStation Eye.
Sony calls it the Playroom and it's more like an interactive toy. The controller and the camera work hand-in-hand to create an AR experience not unlike what Sony is doing now on the PS3 with Wonderbook and Move. It's just that the power of the PS4 lets Sony be just a little more creative in its efforts.
Like most other PlayStation Eye "games," I can see myself playing around this for a few minutes and conclude that it's super charming. Outside of that, it's just a nice tech demo that showcases some of the tech that's available to PS4 gamers. It will be interesting, however, to see what Sony does with the new PlayStation Eye further in the PS4's lifespan and if it will create anything like Wonderbook for it.
The new PlayStation Eye will be available this holiday season alongside the PS4.
