BACKGROUND OF THE INVENTION
Codes—the use of symbols to represent letters and numbers to transmit messages—have been used for centuries. Among the most common of these codes are Morse code, in which letters and numbers are represented by various sequences of dots and dashes (see FIG. 1); phonetic codes, in which letters are represented by symbols, each designating a single sound (see FIG. 2); and the telephone dialing code, in which letters are represented by corresponding numerals (see FIG. 3).
The norm is to display a code separate from its translation. Simultaneous, overlapping display of both is unusual. For example, when using the telephone dialing code, 1-800-CALL ATT, a service mark of the AT&T CORPORATION, for telephone services is most often displayed separate from, or without, the numeric translation, 1-800-225-5288. While presentation of the telephone number as a mnemonic device (i.e., numerals converted to letters, often spelling memorable words) is intended to aid in the recall of the telephone number, the presentation of letters rather than numerals actually makes it more difficult to correctly dial the telephone number, since telephone dialing instruments—rotary dial or keypad—are number dominant.
This fact points out a major drawback to displaying codes separate from their translations if the intent is quick and full comprehension. Extra steps are required to decipher the code, which can also lead to errors in the translation. While the use of the telephone dialing code to present telephone numbers is on the rise among advertisers, so too is the incidence of misdialing these numbers and the attendant annoyance of telephone callers forced to “hunt and peck” which constitutes a change in their normal method of dialing a telephone number.
SUMMARY OF THE INVENTION
The present invention overcomes these and other disadvantages by providing a system and method for presenting a simultaneous, overlapping display of the coded message and its translation as a single, integrated graphic presentation, in any visual medium. A proportionate relationship is maintained between the individual characters in the translation and the individual symbols in the code, in order not only to maximize visibility, but also to minimize any tendency of either the characters of the translation or the symbols of the code to completely or partially obscure the other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
This invention is applicable to any visual medium that could possibly be used to display a coded message. Obvious examples would include, but not be limited to, uses in print media (stationery items such as business cards and letterhead; collateral material such as brochures; advertisements in newspapers, telephone directories, magazines, direct mail, as well as on posters and billboards; novelty advertising such as keychains, coffee mugs, T-shirts, even blimps or hot-air balloons); as well as electronic media (advertisements shown on videotape or film presented on television or in a movie theater; messages shown as liquid crystal displays (LCD) on telephone pagers; lighted displays on electronic billboards; and computer presentations displayed either on the computer screen or projected onto another surface).
Further, this invention is applicable in any visual medium, as noted above, to accommodate the translation of a coded message at any size normally used to display the message. To accommodate the broad range of sizes at which coded messages could be presented, this invention designates different “configurations” (referred to herein and in the drawings) that relate to the size of the characters within the first display area (see FIG. 9). For example, if the characters within the first display area were specified to be 33 point type (approximately ⅜ inch in height) when viewed from a normal reading distance of approximately 18 inches, the Medium Configuration would provide the optimum presentation for the simultaneous display of the coded message together with its translation.
In addition to the Medium Configuration (which has the broadest range of use) there are four other configurations: Extra Small, Small, Large, and Extra Large. The Medium Configuration is used in all the drawings unless otherwise noted. Following is a chart that can be used to determine the appropriate configuration for any simultaneous display of a coded message together with its translation. Examples of the five configurations are shown in FIGS. 40A and 40B.

While many visual displays have an anticipated optimum viewing distance greater than 18 inches—highway signs, billboards, posters, television and movie screens, blimps and hot-air balloons, to name only a few—the chart shown above remains an accurate guide to selecting the appropriate configuration for the simultaneous display of a coded message together with its translation. For example, calculations would need to be done to determine the optimum absolute size of a message viewed from a particular distance (e.g., a highway billboard) to achieve the perception that the relative size of that message was equal to the absolute size of another message (e.g., a magazine advertisement) viewed from a distance of approximately 18 inches.
Thus, the “configurations” referred to in FIGS. 40A and 40B refer to equivalent or relative sizes; the absolute sizes being dependent upon the distance at which a message is intended to be viewed. This is illustrated in FIGS. 41A and 41B.
As is shown by the several drawings, this invention is applicable to both serif and sans serif font styles. In addition, specific font styles may be modified to accurately represent the system of the invention. For example, as shown in FIG. 38, if the characters of a specific font style have a relatively greater width than is preferred for use in this invention, the width of the characters to be modified would be reduced proportionally to their height so as to fit within pre-set borders of the first display area. As shown in FIGS. 38 and 39, the other principal characteristics of each font style are maintained.
Turning now to the drawings, wherein like reference numerals refer to like elements, FIGS. 1-8 depict the prior art with its various disadvantages. The present invention is described beginning in FIG. 9, with its improvements over the prior art.
A discussion of the invention may best begin with a discussion of letter and numeral displays. It has been empirically determined that, in the event of simultaneous display of two types of characters, such as letters and corresponding numerals, the particular size, shape, weight, color and relational information of the characters is important to the visibility and comprehension of the entire message.
One embodiment of the present invention is the simultaneous display of relatively large uppercase, sans serif, roman letters and relatively smaller Arabic numerals overlapped, in order to provide an immediate translation of information found on a telephone keypad or rotary dial. In this embodiment, which could be laid out using a grid such as that shown in FIG. 9, the lighter shaded first display area surrounded by the borders, having dimensions herein labeled “e” and “z,” are normally used for displaying a letter. The smaller and darker shaded second display area, surrounded by the borders having dimensions labeled “a” and “b,” are normally used for displaying a numeral corresponding to the letter on a telephone keypad or rotary dial. The outer borders which contain both display areas, having dimensions labeled “y” and “x,” define the overall display “field” for both characters, i.e., letter and numeral.
FIG. 9 shows an outline of the proportional relationship between the characters. The overall display field for the defined characters, defined by “y” and “x,” preferably is a quadrilateral, most preferably having opposed parallel sides, namely a parallelogram. The first and second display areas, defined herein by “e” and “z,” and “a” and “b,” respectively, are geometrically similar to the overall field, and are usually overlapping. One pair of each of the sides, “e,” “z,” “a,” “b,” is coextensive with portions of opposing sides “y” and “x” respectively. For alphanumeric characters, the numeral in this embodiment is normally displayed as a smaller character within the second display area located in the lower right-hand quadrant of the overall display field.
The overall display field in this embodiment has a constant height, but three possible widths. Specific examples of alphanumeric characters are shown in FIGS. 10-12, each with an overall display field of a different width. Other grid ratios, as shown in succeeding figures, are optimized for other combinations of letters and numerals. As can be seen, the optimal ratios for each grid are different (except for the similarities to be discussed below) due to the fact that letters have different widths. The differences are minimized by the extent that a numeral overlaps a letter while still preserving the integrity of the letter form. For example, the letter “A” in FIG. 10 is optimally overlapped to a greater extent by the numeral “2” than is the letter “I” by the numeral “4” in FIG. 11, causing the difference in width between the two alphanumeric characters to be greatly reduced. This is critical when arranging the alphanumeric characters to form recognizable words, because optically equivalent spacing (letter to letter as well as numeral to numeral) provides optimum visibility and ease of comprehension.
The present invention provides an entire system for systematically displaying and exhibiting, e.g., telephone dialing information, in uppercase, lowercase, italic, roman, positive, reverse, serif and sans serif formats, to maximize comprehension. It further has uses with combinations of characters other than the Latin alphabet and Arabic numerals. For example, for other alphabets, variations can be readily determined; when dealing with the Hebrew or Chinese alphabets, which are read right-to-left or vertically, the relative location of the smaller character may change, as in FIG. 34 where the relative positions of the letter and numeral are varied.
Some of the specific proportions empirically determined in the present invention to yield good visual results are set forth in FIGS. 13-19, which are also labeled as Grids 1-7 for sans serif typefaces. These drawings are substantially to scale, and can be measured to show the ratios used.
FIG. 13 (Grid 1) depicts a Medium Configuration grid suitable for displaying uppercase sans serif letters “B,” “C,” “D,” “G,” “H,” “N,” “O,” “P,” “R,” “S,” “T,” “U” and the small numerals that correspond to each in the telephone dialing code. The following dimensions can be used, for example, in a poster advertisement:
- y=3.60 cm
- x=4.45 cm
- d=2.90 cm
- z=3.85 cm
- a=1.40 cm
- b=2.05 cm
- c=0.55 cm
Preferred relative proportions of the grid dimensions labeled on FIG. 13 are as follows:
- y/x=about 0.6 to about 1.1
- x/z=about 0.9 to about 1.4
- b/x=about 0.2 to about 0.7
- a/b=about 0.5 to about 0.9
- y/a=about 2.3 to about 2.8
- y/d=about 1.0 to about 1.5
- d/a=about 1.8 to about 2.3
- d/z=about 0.5 to about 1.0
FIG. 14 (Grid 2) depicts a Medium Configuration grid suitable for displaying uppercase sans serif letters “A,” “K,” “V,” “X,” “Y” and the small numerals that correspond to each in the telephone dialing code. The following dimensions can be used, for example, in a poster advertisement:
- y=3.60 cm
- x=4.45 cm
- e=3.10 cm
- z=3.85 cm
- a=1.40 cm
- b=2.05 cm
- c=0.55 cm
Preferred relative proportions of the grid dimensions labeled on FIG. 14 are as follows:
- y/x=about 0.6 to about 1.1
- x/z=about 0.9 to about 1.4
- b/x=about 0.2 to about 0.7
- a/b=about 0.5 to about 0.9
- y/a=about 2.3 to about 2.8
- y/e=about 0.9 to about 1.4
- e/a=about 2.0 to about 2.4
- e/z=about 0.6 to about 1.0
FIG. 15 (Grid 3) depicts a Medium Configuration grid suitable for displaying uppercase sans serif letters “E,” “F,” “J,” “L,” a large sans serif numeral “4,” and the small numerals that correspond to each in the telephone dialing code. The following dimensions can be used, for example, in a poster advertisement:
- y=3.60 cm
- x=4.45 cm
- f=2.55 cm
- z=3.85 cm
- a=1.40 cm
- b=2.05 cm
- c=0.55 cm
Preferred relative proportions of the grid dimensions labeled on FIG. 15 are as follows:
- y/x=about 0.6 to about 1.1
- x/z=about 0.9 to about 1.4
- b/x=about 0.2 to about 0.7

FIG. 16 (Grid 4) depicts a Medium Configuration grid suitable for displaying large sans serif numerals “2,” “3,” “4,” “5,” “6,” “7,” “8,” “9,” “0” along with matching small numerals. The following dimensions can be used, for example, in a poster advertisement:
- yn=3.40 cm
- x=4.45 cm
- g=2.30 cm
- z=3.85 cm
- a=1.40 cm
- b=2.05 cm
- c=0.55 cm
It will be noticed in FIG. 16 that the large numerals and the corresponding subscript numerals match. There are instances where this arrangement will be useful; for example, when displaying mnemonic telephone numbers, such as “1-800-MILLER 6” and “1-800-YES 2 ATTSM telephone services.” (See FIGS. 42A and 42B.) It is obvious that the large numerals “6” and “2” do not, strictly speaking, require a translation. However, it has been empirically determined that the accurate translation of a mnemonic telephone number that has a large numeral preceded by a letter, or has a large numeral sandwiched between two letters, is made easier by displaying the large numeral with its matching subscript numeral.
Preferred relative proportions of the grid dimensions labeled on FIG. 16 are as follows:
- yn/x=about 0.5 to about 1.0
- x/z=about 0.9 to about 1.4

- b=2.05 cm
- c=0.55 cm
Preferred relative proportions of the grid dimensions labeled on FIG. 17 are as follows:
- yn/x=about 0.5 to about 1.0

- i=3.20 cm
- z=3.85 cm
- a=1.40 cm
- b=2.05 cm
- c=0.55 cm
Preferred relative proportions of the grid dimensions labeled on FIG. 18 are as follows:

- i/z=about 0.6 to about 1.0
FIG. 19 (Grid 7) depicts a Medium Configuration grid suitable for displaying the uppercase sans serif letter “W” and a small numeral “9,” the corresponding character in the telephone dialing code. The following dimensions can be used, for example, in a poster advertisement:
- yw=3.90 cm
- x=4.45 cm
- k=3.40 cm
- z=3.85 cm
- a=1.40 cm
- b=2.05 cm
- c=0.55 cm
Preferred relative proportions of the grid dimensions labeled on FIG. 19 are as follows:
- yw/x=about 0.7 to about 1.1
- x/z=about 0.9to about 1.4
- b/x=about 0.2 to about 0.7
- a/b=about 0.5 to about 0.9

FIG. 20A is a diagram of the present invention as it is used to display, simultaneously, the uppercase sans serif letters, “A,” “B,” “C,” “D,” “E,” “F,” “G,” “H,” “I,” “J,” “K,” “L,” of the telephone dialing code, together with their numeric translations;
FIG. 20B is a diagram of the present invention as it is used to display, simultaneously, the uppercase sans serif letters, “M,” “N,” “O,” “P,” “R,” “S,” “T,” “U,” “V,” “W,” “X,” “Y,” of the telephone dialing code, together with their numeric translations;
Taken together, FIGS. 20A and 20B represent the information found on a telephone keypad or rotary dial that makes up the telephone dialing code (see FIG. 3). In the Medium Configuration, as can be seen, the first display area (containing letters) is always overlapped by the second display area (containing numerals) causing most of the letters to be overlapped by their corresponding numerals to a greater or lesser extent. But certain letters, specifically, “F,” “P,” “T,” and “Y,” are not overlapped by their corresponding numerals. The grids shown in FIGS. 13 through 19 were used to generate the letters and numerals shown in FIGS. 20A and 20B.
