Abstract

A data entry system having a plurality of a first type of input means, such as keys, to provide input signals to which symbols, such at least the letters of the alphabet of at least one language, are distributively assigned, and such that at least two of the letters are assigned to at least one of the input means, and wherein pressing a key may provide a first input information that ambiguously correspond to any of the letters and a second input information for supporting using a second type of input means for entering unambiguous letters, and wherein the data entry system supports at least one database of words such that in order to enter a desired word of said at least one database, a user of said system selects one or two input methods.

Claims

1. A data entry system comprising:

a plurality of a first type of input means, such as keys, to provide input signals to which symbols, such at least the letters of the alphabet of at least one language, are distributively assigned, and such that at least two of said letters are assigned to at least one of said input means, and wherein pressing a key may provide a first input information that ambiguously correspond to any of said letters; and

a second input information for supporting either one of the following procedures;

using a second type of input means for entering unambiguous letters;

providing additional information corresponding to a letter assigned to said key that is being pressed so that to help the system to select said letter among the symbols that are assigned to said input signal;

wherein said data entry system supports at least one database of words such that in order to enter a desired word of said at least one database, a user of said system employs an entry method selected from the group consisting of;

a first method including combined information corresponding to said word, wherein said combined information includes providing said first input signals such as key presses corresponding to at least some of the characters of said word and providing said second input information to enter precisely at least one character such as a letter of said word through said procedure of input; and

a second method including providing the input signals such as key presses corresponding to substantially all of the characters of said word without providing said additional information.

2. A data entry system as claimed in claim 1, wherein the system compares the information provided through said method with the corresponding information corresponding to the words of said database and proposes a corresponding word, and wherein if the word proposed by the system is not the word desired by the user, then the user may proceed to at least any of the following correction procedures to provide more information to the system, corresponding to the desired word such that

a first correction procedure includes the steps of:

if the proposed word begins with the same letter as that of the desired word, then the user presses a predefined key such as a “

Next”

key and the system proposes the next word of the database corresponding to the combined input information provided by the user and that begins with the same letter as the proposed word;

if the proposed word does not begin with the same letter as the desired word, then the user provides information corresponding to the first character of the desired word such that the system recognizes said character and propose a word corresponding to the combined input information provided by the user and that begins with said letter;

and a second correction procedure includes the steps of;

the user provides information corresponding to the first character of the desired word such that the system recognizes said character and propose a word corresponding to the combined input information provided by the user wherein said word begins with said letter.

3. The system as claimed in claim 1, wherein said second type of input means is a standard PC keyboard or a keypad wherein pressing a key provides a precise character such as letter.

4. The system as claimed in claim 1, wherein said means for entering an unambiguous letter is handwriting and recognition system.

5. The system as claimed in claim 1, wherein said additional information is speaking said letter.
