Abstract
Abstract To efficiently recognize characters from several character sets, a palmtop computer system is disclosed wherein more that one character input area is displayed. Each character input area is designed to recognize strokes that represent characters from a different character set. In one embodiment, the palmtop computer system has an alphabetic input area and a numeral input area. In such an embodiment, strokes entered in the alphabetic input area are interpreted as alphabetic characters and strokes entered in the numeral input area are interpreted as numerals.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
87 words
A computer implemented method of inputting information into a computer system, said method comprising the steps of: providing a first handwriting input area for accepting alphabetic letter strokes; providing a second handwriting input area for accepting number strokes; accepting user input strokes into said first handwriting input area and said second handwriting input area; interpreting user input strokes into said first handwriting input area as alphabetic characters but not numbers; and interpreting user input strokes into said second handwriting input area as numbers but not alphabetic characters.
Claim 2
Dependent Claim
87 words
A computer implemented method of inputting information into a computer system, said method comprising the steps of: providing a first handwriting input area for accepting alphabetic letter strokes; providing a second handwriting input area for accepting number strokes; accepting user input strokes into said first handwriting input area and said second handwriting input area; interpreting user input strokes into said first handwriting input area as alphabetic characters but not numbers; and interpreting user input strokes into said second handwriting input area as numbers but not alphabetic characters.
Claim 3
Dependent Claim
30 words
The method of claim 1 wherein said steps of interpreting user input strokes comprise immediately recognizing a character after said user completes at least one stroke that defines a character.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein said steps of providing said first and said second handwriting input area comprise labeling a defined area on a digitizer pad.
Claim 5
Dependent Claim
21 words
The method of claim 1 further comprising the step of: displaying a interpreted input stroke as a character onto a display.
Claim 6
Dependent Claim
116 words
A computer implemented method of inputting information into a computer system, said method comprising the steps of: providing a first handwriting input area for accepting a first set of strokes for a first character set; providing a second handwriting input area for accepting a second set of strokes for a second character set; accepting user input strokes into said first handwriting input area and said second handwriting input area; interpreting user input strokes into said first handwriting input area as characters from said first character set but not said second character set; and interpreting user input strokes into said second handwriting input area as characters from said second character set but not said first character set.
Claim 7
Dependent Claim
116 words
A computer implemented method of inputting information into a computer system, said method comprising the steps of: providing a first handwriting input area for accepting a first set of strokes for a first character set; providing a second handwriting input area for accepting a second set of strokes for a second character set; accepting user input strokes into said first handwriting input area and said second handwriting input area; interpreting user input strokes into said first handwriting input area as characters from said first character set but not said second character set; and interpreting user input strokes into said second handwriting input area as characters from said second character set but not said first character set.
Claim 8
Dependent Claim
13 words
The method of claim 5 wherein said first character set comprises alphabetic characters.
Claim 9
Dependent Claim
13 words
The method of claim 6 wherein said second character set comprises Arabic numerals.
Claim 10
Dependent Claim
30 words
The method of claim 5 wherein said steps of interpreting user input strokes comprise immediately recognizing a character after said user completes at least one stroke that defines a character.
Claim 11
Dependent Claim
109 words
A pen-based computer apparatus, said pen-based computer apparatus comprising the elements of: a display screen; and a digitizer pad; and a first handwriting input area, said first handwriting input area comprising a first subarea of said digitizer pad; and a second handwriting input area, said second handwriting input area comprising a second subarea of said digitizer pad; and a handwriting interpreter, said handwriting interpreter interpreting strokes written into said first handwriting input area as characters from a first character set but not said second character set and interpreting strokes written into said second handwriting input area as characters from a second character set but not said first character set.
Claim 12
Dependent Claim
109 words
A pen-based computer apparatus, said pen-based computer apparatus comprising the elements of: a display screen; and a digitizer pad; and a first handwriting input area, said first handwriting input area comprising a first subarea of said digitizer pad; and a second handwriting input area, said second handwriting input area comprising a second subarea of said digitizer pad; and a handwriting interpreter, said handwriting interpreter interpreting strokes written into said first handwriting input area as characters from a first character set but not said second character set and interpreting strokes written into said second handwriting input area as characters from a second character set but not said first character set.
Claim 13
Dependent Claim
13 words
The apparatus of claim 9 wherein said first character set comprises alphabetic characters.
Claim 14
Dependent Claim
13 words
The apparatus of claim 10 wherein said second character set comprises Arabic numerals.
Claim 15
Dependent Claim
