Abstract
A multi-contact character input method includes: setting an input character corresponding to each multi-contact operation, in which attributes of the multi-contact operation include a position of each contact in a plurality of contacts, or/and the number of contacts contacting a multi-point touch screen within the same time, or/and a sliding direction of each contact; a user performing a multi-contact operation; identifying the multi-contact operation of the user and obtaining a corresponding input character according to the attributes of the multi-contact operation; and inputting the corresponding character. The multi-contact character input method fully uses the advantages of multi-point touch sensing, implements the input of frequently used functional keys or character keys through a multi-point touch combination of a special manner, and provides input convenience for the user without requiring the user to change a click input mode.
