Data entry system

Abstract

A data entry system includes a plurality of keys each of which has two or more symbols associated with each key and a means for receiving a second specific input from a user. A third correction key is provided, where a user enters a desired input by pressing one or more of the plurality of keys corresponding to the symbols required for the desired input and further provides a second specific input also relating to at least a portion of the desired input, such that the system produces a response to the desired input by predicting the desired input based on the symbols pressed by the user and based on the second specific input. If the produced response is different than the desired input, the user may press the correction key to scroll through additional less frequent responses from the system also matching the symbols pressed and the second specific input.

1 . A data entry system comprising: 
 a plurality of input receiving means for at least entering arbitrary characters, wherein each said receiving means is assigned more than one character, such that a user uses said input receiving means to enter a desired input; and    a second input receiving means for receiving a second input, wherein said second input is a precise character or characters from said desired input; wherein said system provides a predictive output based on input from at least said plurality of input receiving means,    wherein if said predictive output is different from said desired input and said first letter of said desired input is different than said first letter of said predictive output, said user may enter a predefined correction signal to provide a first character of said desired input, such that said system may provide a second predictive output is based on the previously provided input from the user and said correction signal.    
     
     
         2 . The system as claimed in  claim 1 , wherein said correction signal is provided through one of the group consisting of speech, handwriting, and a key press.  
     
     
         3 . The system as claimed in  claim 1 , wherein if said predictive output is different from said desired input and said first letter of said desired input is the same as said first letter of said predictive output, said user may enter a predefined correction signal to provide scroll through additional less frequently occurring choices from said system also having the same first letter as the predictive output
