Have you seen movie Minority Report of Tom Cruise? Doing the sixth sense detection and working on computers with fingers..

Here in this video, you can see a guy who made a prototye which works similar to the technology. He just wears the devices like projector, camera, mobile and caps on fingers. He can take photographs, resize it then and there it self projecting on walls or any surface.
Just imagine it is connected to internet, thats it, what not you can do? You can broadcast anything live, anywhere, post photos, videos on internet and many many things which ever comes to your imagination.

Also some of the applications are shown which are amazing like, Making hand as a screen and using your finger pressing buttons and making calls. Getting information on books, foods, etc.. This says that its just like a robot watching every moment what you are doing and helping you in all the matters through the information availiable on internet or anywhere else.

It can be also taken that in future this will make a history and detecting sixth sense. It is like sixth sense technology.
