Any accessory for a smartphone should be comparable in size with it, otherwise the mobility and comfort of work contort dramatically. A different matter, if the device does not have a constant physical form, as in the case of the keyboard Masterkey 4.0, which is projected by a laser beam to the surface. In the deactivated form, it is no more than a cover for a smartphone, in the active – in front of you a full-sized QWERTY keyboard for working with documents.

The picoprojector provides an increase in the image up to 120 inches diagonally, however at the maximum resolution of 854×480 pixels the image does not differ in detail.
The contrast parameter is 2000: 1, the brightness is not more than 100 lumens, manual correction of sharpness. By default, a keyboard with dimensions of 245×110 mm is projected, an integrated infrared camera tracks “pressing” at speeds of up to 350 characters per minute.
Masterkey 4.0 connects to a smartphone with iOS / Android via Bluetooth 4.0, and to other devices via USB or HDMI. The built-in battery capacity is 5200 mAh, there is a microSD port.
The startup offers two versions of a projected keyboard, a basic one at $ 179 and a business model for $ 225. If the fundraising is going according to plan, Masterkey 4.0 will be available in January 2019.
