Virtual Keyboard in the housing fob

Typing on a touch screen 7-inch tablet is not very convenient, so size virtual keyboard is very modest. Carrying a keyboard, even a relatively compact and wireless, is also very uncomfortable. Such keyboard can  worn as a pendant, along with the keys.
Of course, the keyboard-fob may not have a complete set of mechanical buttons, so here uses an interactive laser projection. Image of classic QWERTY-layout appears on any flat surface next to a Tablet PC, and set the text at once becomes more fun. And this keyboard connects wirelessly to Bluetooth.
The device is powered by a built-in rechargeable lithium-ion battery that is charged via the included USB-cable. When working with a smartphone or a modest 7-inch tablet, the benefits of such a keyboard is obvious, but the 10-inch tablet has a keyboard roughly the same size, so here the choice solely on the fan.
