- a set of keys approximately arranged by folding an arrangement of a Qwerty keyboard, the set of keys including a right-handed input arrangement and a left-handed input arrangement respectively responding to a right portion and a left portion of the Qwerty keyboard, such that each of the keys corresponds to at least two characters including a first character in the left portion of the Qwerty keyboard and a second character in the right portion of the Qwerty keyboard;
a first means, disposed on a left side of a bottom of the set of keys, for detecting a first motion corresponding to the left-handed input arrangement;
a second means, disposed on a right side of the bottom of the set of keys, for detecting a second motion corresponding to the right-handed input arrangement; and
an activation mechanism configuredto activate the set of keys in the left-handed input arrangement, corresponding to the left portion of the Qwerty keyboard, in response to the detection of the first motion,to activate the set of keys in the right-handed input arrangement, corresponding to the right portion of the Qwerty keyboard, in response to the detection of the second motion, andto selectively activate, for each pressed key, the first character or the second character in response respectively to the detection of the first motion or the second motion,wherein the key input system is free of independent numeral keys.

22. A key input system, comprising:
-
a set of keys corresponding to a first half of a full Qwerty keyboard when in a left-hand mode, and corresponding to a second half of the full Qwerty keyboard when in a right-hand mode, each of the keys corresponding to at least two characters including a first character in the first half of the full Qwerty keyboard and a second character in the second half of the full Qwerty keyboard; and a first means, disposed on a left side of a bottom of the set of keys, for detecting a first motion corresponding to the left-hand mode; a second means, disposed on a right side of the bottom of the set of keys, for detecting a second motion corresponding to the right-hand mode; and an activation mechanism configured to selectively activate, for each pressed key, the first character or the second character in response respectively to the detection of the first motion or the second motion, to input the corresponding first character in response to the detection of the first motion, and to input the corresponding second character in response to the detection of the second motion, wherein the key input system is free of independent numeral keys.
