Abstract

A double-sided keyboard comprises a rearward-facing keyboard, a traditional front-facing keyboard and a hinging means. The double-sided keyboard is assembled in a way that the rearward-facing keyboard is on one side of the double-sided keyboard while the traditional front-facing keyboard is on another side of the double-sided keyboard. The hinging means, being on one edge of the double-sided keyboard, is used for connecting to one edge of a tablet computer or mobile computing device, and further provides a sliding mechanism for guiding the sliding motion of the double-sided keyboard. When the double-sized keyboard is attached on to back of a mobile computing device, the rearward-facing keyboard is facing rearward away from the user as the user holds and faces the display screen of the mobile computing device, so that the fingers of the user are free to press the rearward-facing keys on the rearward-facing keyboard. When the double-sided keyboard is slide out, through the sliding mechanism of the hinge, from the back of the mobile computing device, the traditional front-facing keyboard is laid before its user such that the user can type, resembling typing on a laptop computer.
