Abstract

An improvement in a electronic crossword puzzle solving machine to provide alternate words for a word that is input on the keyboard. A first actuation of a function key labeled "Second-Guess" initiates a search in which all words in memory having the same number of letters as the input word but differing with respect to only one of those letters is displayed. A second actuation of the "Second-Guess" key results in a search and display of all words differing from the input word with respect to two of the letters. Each successive actuation of the "Second-Guess" key increases the number of letters by which the alternate words found differ from the input word.

Claims

1. In a word selection machine having a predetermined set of words in memory and having matching means for matching an input partial word against said set of words to provide a suggested word, the improvement in providing alternate suggested words comprising:

keyboard means to provide a user selected input word,

a display screen to display said user selected input word,

a predetermined function key on said keyboard,

first search means responsive to a selected input word of Y letters and a first actuation of said function key to provide on said display screen a first list of Y letter long words from said set of words in memory,

each member of said first list of words differing from said input word by one letter.

2. The improvement of claim 1 further comprising:

second search means responsive to a second actuation of said function key to provide on said display screen a second list of Y letter long words from said set of words in memory,

each member of said second list of words differing from said input word by two letter-positions.

3. The improvement of claim 1 further comprising:

indicia means to indicate which letter on each member of said first list of words differs from the corresponding positioned letter of said input word.

4. The improvement of claim 2 further comprising:

indicia means to indicate which letters of said second list of words differ from the letters in the corresponding letter positions of said input word.

5. The improvement of claim 2 wherein said first and second list of words are both displayed in response to a search by said second search means.

6. The improvement of claim 3 wherein said indicia means constitute displaying said differing letter in a different typeface.

7. The improvement of claim 4 wherein said indicia means constitutes displaying said differing letters in a different typeface.

8. In a word selection machine having a predetermined set of words in memory and having matching means for matching an input partial word against said set of words to provide a suggested word, the improvement in providing alternate suggested words comprising:

keyboard means to provide a user selected input word,

a display screen to display said user selected input word,

a predetermined function key on said keyboard,

search means responsive to a selected input word of Y letters and a Nth actuation of said function key to provide on said display screen a list of words from said set of words in memory,

each member of said list of words having Y letters and having at least (Y-N) letters the same in value and position as said input word.

9. In an electronic crossword puzzle solver wherein a user entered partial word having Y letter positions will provide a plurality of words with the Y letter positions filled in from a predetermined list of words in memory, the improvement in providing alternate words for fully entered words comprising:

matching means responsive to a user entered complete N letter input word to compare said input word with the predetermined set of words in memory to provide a list of alternate words,

said alternate words constituting those words in memory having Y letters in which Y-1 letters correspond in designation and position with Y-1 letters of said input word,

display means to display each of said words from said list of alternate words,

said display means including means to uniquely designate the letter of said alternate word which does not match the corresponding letter of said input word.
