Information processing method and apparatus for a touch screen device

Abstract

An information processing method for a touch screen device includes in response to contact of a user's finger with a touch screen of the touch screen device, identifying the finger contacting the touch screen; determining key(s) corresponding to the identified finger based on set correspondence relationship(s) between the finger(s) and the key(s); and displaying at least one character represented by the key(s) corresponding to the identified finger.

1 . An information processing apparatus for a touch screen device, the apparatus comprising:
 an identifying module configured to, in response to contact of a user's finger with a touch screen of the touch screen device, identify the finger contacting the touch screen;   a determining module configured to determine key(s) corresponding to the identified finger based on set correspondence relationship(s) between finger(s) and key(s);   a displaying module configured to display at least one character represented by the key(s) corresponding to the identified finger.   
     
     
         2 . The apparatus according to  claim 1 , wherein the displaying module comprises at least one of the following sub-modules:
 a first displaying sub-module configured to display in a to-be-input area at least one character represented by the key(s) corresponding to the identified finger;   a second displaying sub-module configured to display in a to-be-selected area at least one character represented by the key(s) corresponding to the identified finger;   a third displaying sub-module configured to display all characters represented by the key(s) corresponding to the identified finger.   
     
     
         3 . The apparatus according to  claim 2 , wherein the second displaying sub-module comprises a first display sub-module configured to determine possible combination(s) of the characters already existing in the to-be-selected area and the characters represented by the key(s) corresponding to the identified finger, and display in the to-be-selected area at least one of the possible combination(s). 
     
     
         4 . The apparatus according to  claim 3 , further comprising a clearing module configured to clear the to-be-selected area in response to the user terminating the input. 
     
     
         5 . The apparatus according to  claim 1 , further comprising a relational module configured to display the correspondence relationship(s) between the finger(s) and key(s). 
     
     
         6 . The apparatus according to  claim 1 , further comprising a selection display module configured to display the selected characters in response to determining the contact between the user's finger and the touch screen as performing a selection. 
     
     
         7 . The apparatus according to  claim 1 , further comprising:
 a space determining module configured to determine a space to which the contact between the user's finger and the touch screen of the touch screen device belongs, wherein the touch screen comprises a plurality of spaces; and   wherein the identifying module comprises a second key identification sub-module configured to determine key(s) corresponding to the identified finger based on the correspondence relationship(s) between finger(s) and key(s) in the belonging space.   
     
     
         8 . A touch screen device, comprising:
 a touch screen and the apparatus according to  claim 1 .
