Description
Background of the Invention
In many types of programmed apparatus, interaction with a user is obtained by displays on a cathode ray a native language of menus, actions to be taken, and messages for helping the user when he requests aid. All of this information, along with instructions as to the format of the display, are stored in a native language file that is scanned by a screen generator that controls the cathode ray tube.
For the apparatus to be used by someone who is not familiar with the native language, a translation of the displayed words into suitable foreign equivalents is required. This has been obtained by recording the various displays and format descriptions on paper and sending it to a translator after the words to be translated have been designated in some way, as for example with a magic marker. After the designated words have been translated into foreign equivalents and recorded on the paper, it is used to create a foreign language file that is sent with apparatus sold to people familiar with that language. Whereas this may seem to be a simple and straightforward procedure, experience has shown that much confusion and delay results from the use of paper recording in this manner, e.g., the translator may provide words that are not apt because he is not familiar with the application or he may fail to observe the format instructions and use a foreign word that is too long.
Brief Summary of the Invention
In accordance with this invention, the words in a native language file that are to be translated, comment language related to these words, and format instructions are individually identified by the grammatical construction employed. The file is then read by a special translation tool that displays the words to be translated on the screen of a cathode ray tube in a format of its own. This is done in such manner that the allotted space for a word or phrase is readily discernable, e.g., by video inversion, and a similarly designated space for a foreign word is identified at some adjacent location. Also included in the displays are any comments required for the purpose of helping the translator select appropriate foreign words. The translation tool is also provided with a means for inserting a foreign word into the space designated for it. Thus, if the selected foreign word is too long, the translation tool will not allow the user to enter the extra letters. If desired, a report generator may be provided for printing only the native language and foreign language words so that they can be verified. The translated words are then placed in a foreign language text file and means are provided for forming a foreign language file in which the translated words are substituted for the native words so that it can be used with apparatus for sale to a foreign country using that foreign language.

Detailed Description of the Invention
In the block diagram of FIG. 1 native language, file Fn contains format instructions, native words to be translated and comment information for the purpose of aiding the translator in making a more apt selection of foreign words to be substituted for the native words. As noted in the example set forth immediately below, the format instructions are in clear language, the native words to be translated are in quotes and the comment information is preceded by a dollar sign ($). Thus, each type of information can be separately identified from its grammatical construction.
If the file is to be used for forming displays in the native language in a computer, the information in the native language file Fn is directly used by a screen generator SG to form the desired displays on the cathode ray tube, not shown, contained in the computer C.
But if the file Fn is to be used with apparatus employing a foreign language, suitable foreign words must be substituted in the file Fn, yielding a foreign language file Ff. A translation tool T scans the native language file Fn and resents the native words in quotes at certain places on the screen of its cathode ray tube, not shown, as well as the comment messages indicated by the dollar sign ($). From the instructions for the format to be used in the display in the computer, the translation tool derives information as to the size and shape of the space allotted to the native words to be translated and presents them on a screen in such manner that this space can be readily identified. A blank space of identical dimensions but having no letters in it is also presented at a convenient location on the screen. Various means for providing the identification of the space may be used, e.g., outlining or inverse video. FIG. 1A illustrates the use of the latter technique in presenting the word "assign" from the native language file Fn set forth above. When the native language to be translated is one or two words as in the case of "assign", it is expedient for the blank space for the foreign word to be placed at one side, as in FIG. 1A; but if the native words form a line or several lines as may be the case in help prompts, the blank space may be below the space occupied by the native text.
In addition to the native words in quotes that are to be translated, the translation tool presents the comment language grammatically denoted by a dollar sign ($).
Means are provided for the translator to insert suitable foreign language words in the indicated blank spaces. If the word selected is too long, any characters beyond the maximum word length cannot be entered in the blank space so that the translator will know that another foreign word or words must be found. FIG. 1B shows that, although the English word "assign" has six letters, the identified space is for seven letters so that the German word "zuweisn" fits in the allotted space.
The translated words may be verified by printing them on paper for review purposes. In any event, they are stored in a foreign language text file Ft, and an overlay means O is provided for merging the information in the files Fn and Ft so as to provide a foreign language file Ff that is the same as Fn except that a foreign word such as "zuweisn" is substituted for the native quoted word such as "assign". The foreign language file Ff set forth below can be used with the same equipment to form displays in the foreign language. The translation needs to be done only once, because once a foreign language file Ff has been created, it can be copied.
In some situations, the design of the various means in an equipment for forming displays is available before the design of the rest of the equipment so that testing of the display process can be performed by providing a verification tool V that forms displays in the same way as the completed equipment will do and controlling it with the screen generator SG when the latter is coupled to the foreign language file Ff as indicated by the dashed lines in FIG. 1.
Although screen generators are well known to those skilled in the art, reference is now made to FIG. 1C for a more detailed description of same. In this particular case, the generator is operated by a Hewlett-Packard 9000-S500 computer in accordance with a program set forth at the end of the specification.
The native language file Fn is coupled to a screen generator SG that acts as a compiler for deriving the assembly language required to drive a cathode ray tube. The screen generator SG is comprised of a scanner 2 that pulls out each word in the file Fn in sequence and stores a numerical representation thereof in a token file 4 that checks to see if each word is in its vocabulary, a parser 6 that checks the grammar, element descriptor tables 8 that provide abbreviations for certain phrases, and a code generator 10 that provides the required assembly language. The output of the code generator 10 is read into a screen data constants file 12. An assembler 14 translates the constants into language stored in a file 16 that can be used to control the computer C.
If desired, the translation can be checked by applying it from the assembler 14 to a verification tool V which operates in the same manner as the video portion of the equipment.
Reference is now made to FIG. 1D for a description of a translation tool of this invention. It is controlled by a Hewlett-Packard 150 Personal Computer in accordance with a program set forth at the end of the specification.
An indexer 22 scans the file Fn and calculates from the format information therein the locations of all text to be translated, stores indeces of the text and its allotted length, and reserves space in an indexed language text file Fi.
A formatter 24 reads the indexed language text file Fi and reformats the text to be displayed on a screen of a cathode ray tube 26 showing the native language to be translated as well as the comment information indicated by dollar signs ($). The actual operation of the cathode ray tube 26 is via an input/output driver 28. When the translator types the foreign word to be substituted for the native word on a keyboard 30 of the computer, the foreign word appears in the blank space reserved for it as indicated in FIG. 1B. If requested by the user, the translated text is stored in a foreign language text file Ft by an updating means 33.
After part or all of the translation is completed in this manner, a report can be printed by a report generator 34 so that the native and foreign language words can be compared, but this is not essential.
When the translation is complete and all foreign words have been loaded into the foreign language text file Ft, the foreign language file Ff is generated by storing the foreign language words in the places reserved for them. An overlay means 0 that is coupled to the foreign language text file Ft and to the native language file Fn merges the native language text in Fn and the translated language of the intermediate file 32 so as to produce the foreign language file Ff that can be used with a computer to be used by those familiar with the particular foreign language. The file Ff is simply substituted for the file Fn. When this is done, the portion of the file Fn previously set forth will appear as set forth below when the foreign language is German. If, after verification of the foreign language, it is found that corrections are necessary, the foreign language file Ff may be used as input to the translation tool T to permit corrections to be made. ##SPC1##
