Abstract

A text processing device for stenographic typing comprises an alphanumerical keyboard, a translation device, a read/write memory and a display device. Given, frequently occurring words can be entered into the device in abbreviated form. Words of a main set are entered by way of a sequence of two or more key strokes. At least the first two thereof each define a word part to be separately pronounced, for example, in that they constitute the first letters of respective syllables. The full word corresponding to an abbreviated word is formed by the translation device in that at least one missing letter is inserted each time between two successively entered letters. By also providing one or more smaller auxiliary sets of abbreviations, there is an overall saving as regards the number of key strokes required to enter a text.

Claims

1. A text processing device comprising:

input means for entering into the text processing device alphabetic information in the form of complete words or as abbreviated words defined by one or more syllabic word parts of given individual complete words of said alphabetic information,

a display device for displaying in legible form a text represented by a series of words,

a read/write memory for storing words represented by a sequence of letters and having an output coupled to an input of said display device, and

a translation device coupled to said input means and to said read/write memory thereby to apply an abbreviated word identified by a sequence of keystrokes to said read/write memory in a complete form by supplementing missing letters, said translation device comprising;

means for storing a plurality of abbreviated words made up of syllabic word parts corresponding to said syllabic word parts of said abbreviated input words, said plurality of stored abbreviated words made up of syllabic word parts comprising a majority of the words to be processed by the text processing device, and wherein each sequence of letters of an abbreviated word does not occur as a valid word in a standard text,

a control device coupled to said input means for detecting a received control signal indicative of the reception of an abbreviated word,

means controlled by said control device and responsive to abbreviated words received by said input means and to abbreviated words stored in said storing means for determining coincidence thereof and, upon coincidence, supplementing one or more missing letters between successive letters of said abbreviated words to form a complete word corresponding to said abbreviated word,

a storage device controlled by said coincidence determining means for storing said complete word which corresponds to the abbreviated word, and

means for selectively transferring a complete word in said storage device to said read/write memory.

2. A text processing device as claimed in claim 1 wherein said input means are adapted for connection to a keyboard for entering letters into said text processing device via successive keystrokes of the keyboard, wherein for an abbreviated word, of a principal set of words, comprising a sequence of at least two keystrokes, said coincidence determining and supplementing means inserts at least one missing letter between two successively entered letters.

3. A text processing device as claimed in claim 2 wherein for a word of the principal set of words identified by a sequence of at least three key strokes, at least one missing letter is inserted each time by said coincidence determining and supplementing means between two successively entered letters and the relevant sequence contains letters spatially distributed over the word in question.

4. A text processing device as claimed in claim 2 wherein said sequence of key strokes successively comprises at least two initial letters of syllables.

5. A text processing device as claimed in claim 4, wherein said sequence of key strokes is further supplemented by at least one key stroke identifying the form of an ending.

6. A text processing device as claimed in claim 2, wherein said control device activates said translation device by a space stroke immediately following said sequence.

7. A text processing device as claimed in claim 2, wherein said control device activates said translation device by an activation key stroke which directly succeeds the sequence.

8. A text processing device as claimed in claim 2, wherein individual multi-letter words are assigned to substantially all separate letter keys.

9. A text processing device as claimed in claim 2, wherein given series of words are associated with a predetermined number of sequences of key strokes, the letters indicated by the key strokes forming the first letters of the series of words, the relevant total sequence forming a sequence which does not occur as a valid word in a standard text.

10. A text processing device as claimed in claim 2, wherein days of the week are represented by a selection mark and a dyad of key strokes.

11. A text processing device as claimed in claim 2, wherein months of the year are represented by a selection mark and a month sequence number within the year.

12. A text processing device as claimed in claim 2, wherein the control device is responsive to an inadmissible sequence of key strokes to control the translation device to remain de-activated so that the sequence of letters is applied to the read/write memory in unmodified form.

13. A method of entering an alphabetic text into a computer using abbreviated word forms and translating the abbreviated word forms into their corresponding complete word forms comprising:

for a majority of words, entering into the computer a sequence of alphabetic characters comprising less than all of the characters in said words, said sequence comprising an abbreviated word form including the first letter of each syllable of the corresponding complete word,

comparing each said abbreviated word form with a stored dictionary of corresponding abbreviated word forms and when a match is established,

translating said abbreviated word form into its corresponding complete word form by inserting one or more missing letters between each two successive letters of the abbreviated word form, and

storing, at least temporarily, in said computer the complete words corresponding to matched abbreviated words.

14. A method as claimed in claim 13 wherein said alphabetic text is entered by means of a keyboard wherein at least the first two letters of the sequence comprise letters spatially distributed over the word where each of said first two letters define a word part to be separately pronounced, and wherein each sequence of letters forming an abbreviated word form does not occur as a valid word in a standard text of words.

15. A method as claimed in claim 13 wherein said translating step is performed by a translation device in said computer, said method further comprising, prior to said translating step, activating said translation device in response to a space stroke signal which immediately follows said sequence of characters in abbreviated word form.

16. A method as claimed in claim 13 wherein, for a minority of words of said alphabetic text, the method further comprises entering complete word forms into the computer and, if a match is not established during said comparing step, said translating and storing steps are bypassed, and

applying the entire sequence of letters of said complete word forms to a memory device in said computer.
