A character inputting method, comprising: detecting a pressing operation made by a user on a touch panel of a mobile terminal at a display region of a keyboard when the keyboard for inputting characters is displayed on the display panel of the mobile terminal; acquiring a pressure detection value for the pressing operation and a target key on which the pressing operation is performed when the pressing operation has been detected, characters corresponding to the target key comprising first-type characters and second-type characters, and each of the first-type characters and the second-type characters comprising at least one character; selecting one character from the first-type characters corresponding to the target key and inputting the selected character into a predetermined word editable region when the pressure detection value is greater than a predetermined threshold; and selecting one character from the second-type characters corresponding to the target key and inputting the selected character into the predetermined word editable region when the pressure detection value is smaller than or equal to the predetermined threshold, characterized in that, wherein subsequent to selecting one character from the first-type characters corresponding to the target key and inputting the selected character into the predetermined word editable region and subsequent to selecting character from the second-type characters corresponding to the target key and input the selected character into the predetermined word editable region, the character inputting method further comprises: adjusting the predetermined threshold in accordance with a next word editing operation performed after each pressing operation, wherein the adjusting the predetermined threshold in accordance with the next word editing operation performed after each pressing operation comprises: determining whether the next word editing operation performed after each pressing operation is a cancelling operation; recording, when the next word editing operation performed after each pressing operation is the cancelling operation, the pressure detection value for the pressing operation, and determining an average of the recorded pressure detection values as an adjusted threshold when the times of recording the pressure detection values reach a predetermined value; and maintaining the predetermined threshold when the next word editing operation performed after each pressing operation is not the cancelling operation, wherein after the pressing operation has been made by the user and before a finger of the user moves away from the touch panel, a character displayed at a predetermined region of the display panel is changed in real time in accordance with a change in the pressure detection value for the pressing operation. detecting a pressing operation made by a user on a touch panel of a mobile terminal at a display region of a keyboard when the keyboard for inputting characters is displayed on the display panel of the mobile terminal;
