27. A text input method executable by an electronic device connectable to a display and capable of detecting touch operations, comprising: displaying a virtual keyboard comprising a plurality of keys; utilizing the virtual keyboard as a base for one or more touch operations detectable by a touch detection function, wherein each key of the plurality of keys is operable as a toggle key and is associated with one or more characters for input to a text area; selecting a first initially selected character associated with a first activated key in response to a first touch operation based on the first activated key in the plurality of keys of the virtual keyboard, wherein the first touch operation is detectable by the touch detection function and comprises an operation of a press, an operation of a touch movement track, or a combination of an operation of a press and an operation of a touch movement track; selecting a second initially selected character associated with a second activated key in response to a second touch operation based on the second activated key in the plurality of keys of the virtual keyboard after the first touch operation, wherein the second touch operation is detectable by the touch detection function and comprises an operation of a press, an operation of a touch movement track, or a combination of an operation of a press and an operation of a touch movement track; utilizing the first initially selected character or a first related character associated with the first initially selected character as a first determined character; utilizing the second initially selected character or a second related character associated with the second initially selected character as a last determined character; generating an auto-completed word based on a database of words in response to the second touch operation, wherein the auto-completed word comprises the first determined character as a leftmost character of the auto-completed word and the last determined character as a rightmost character of the auto-completed word; presenting the auto-completed word as an option in a first graphical user interface component in response to activation of the second activated key; and entering the auto-completed word to the text area in response to an assistant touch operation associated with the option in the first graphical user interface component, wherein the assistant touch operation is detectable by the touch detection function.
