Smartphone is an easy-to-use hands-free, but not all-in-one, full-featured display, which can be applied to smartphones. Developers of "Carnegie Mellon"'s Future Interfaces Group (FIG) have proposed this for the latest technology issue: why do not you overwrite the screen handsfree?

It sounds fantastically, but the prototype apparatus is already working. On the basis of the development of the FIG is a laser projection: it creates an active domain - the "virtual tachskrin" in the area of about 40 cm2. With the help of this smartphone you can use all the functions of the smart clock, or not to get off the smartphone: just like, unlock the device, open the application and work with it.

By the way, the screen-projections are either not bright or contrasted, but the screen is perfectly adapted to the geometry of the human body. The video developers can demonstrate the possibility of a new gadget.
