Keyboard device and keyboard cover

A keyboard device comprising a plurality of character keys having identical shapes, each of the character keys including a finger identifier identifying a kind of a finger with which each of the character keys is to be pressed, a color or a shape of the finger identifiers being different from each other depending on the kinds of the fingers, and in each of the fingers, the finger identifier for a left hand being mirror symmetrical with respect to the finger identifier for a right hand;

• wherein corresponding to a QWERTY arrangement, the plurality of character keys are divided into eight areas including:
• a first area having the character keys of “1”, “Q”, “A” and “Z”;
• a second area having the character keys of “2”, “W”, “S” and “X”;
• a third area 3 having the character keys of “3”, “E”, “D” and “C”;
• a fourth area having the character keys of “4”, “5”, “R”, “T”, “F”, “G”, “V” and “B”;
• a fifth area having the character keys of “6”, “7”, “Y”, “U”, “H”, “J”, “N” and “M”;
• a sixth area having the character keys of “8”, “I”, “K” and “<”;
• a seventh area having the character keys of “9”, “O”, “L” and “>”;
• and
• an eighth area having the character keys different from the character keys belonging to each of the first to seventh areas,
• wherein in the first to fourth areas, each of the finger identifiers is arranged at a left side surface of a character key among the characters keys which is to be pressed by the left hand without being arranged at a right side surface thereof such that the finger identifiers also serve as a hand identifier, and
• in the fifth to eighth areas, each of the finger identifiers is arranged at a right side surface of a character key which is to be pressed by the right hand without being arranged at a left side surface thereof such that the finger identifiers also serve as a hand identifier.

A keyboard cover comprising key cover cells which cover a plurality of character keys of a keyboard device respectively, the character keys having identical shapes, each of the key cover cells including a finger identifier identifying a kind of a finger with which each of the character keys is to be pressed, the finger identifier for a left hand being mirror symmetrical with respect to the finger identifier for a right hand;

• wherein corresponding to a QWERTY arrangement, the plurality of character keys are divided into eight areas including:
• a first area having the character keys of “1”, “Q”, “A” and “Z”;
• a second area having the character keys of “2”, “W”, “S” and “X”;
• a third area 3 having the character keys of “3”, “E”, “D” and “C”;
• a fourth area having the character keys of “4”, “5”, “R”, “T”, “F”, “G”, “V” and
• a fifth area having the character keys of “6”, “7”, “Y”, “U”, “H”, “J”, “N” and
• a sixth area having the character keys of “8”, “I”, “K” and “<”;
• a seventh area having the character keys of “9”, “O”, “L” and “>”;
• and
• an eighth area covering the character keys different from the character keys belonging to each of the first to seventh areas,
• wherein in the first to fourth areas, each of the finger identifiers is arranged on an upper left corner portion of each of the key cover cells without being arranged on an upper right corner portion thereof such that the finger identifiers also serve as a hand identifier, and
• wherein in the fifth to eighth areas, each of the finger identifiers is arranged on an upper right corner portion of each of the key cover cells without being arranged on an upper left corner portion thereof such that the finger identifiers also serve as a hand identifier.
