Abstract

A method for controllable toggling viewing of written materials with adjuvant or explanatory notation material as a teaching or memorization tool. The method comprises the steps of imprinting adjuvant or explanatory notation materials adjacent to or in close conjunction with a visible text or notation, as a non visible or an invisible imprint. The non visible invisible adjuvant or explanatory notation material is made to become temporarily visible or viewable with a heat source or a viewing device for a controlled desired period of time by using the visible adjuvant or explanatory notation to perform a reading or writing function. Removing the viewing device or reducing heat renders the adjuvant or explanatory notation non visible or invisible.

Claims

1. A method for controllable toggling viewing of written materials with adjuvant or explanatory notation material as a teaching or memorization tool, wherein the method comprises the steps of: i) imprinting adjuvant or explanatory notation materials adjacent to or in close conjunction with a visible text or notation, as a non visible or an invisible imprint; ii) selectively causing the non visible or invisible adjuvant or explanatory notation material to become temporarily visible or viewable with a viewing means or device for a controlled desired period of time; iii) using the visible adjuvant or explanatory notation to perform a reading or writing function; iv) removing the viewing means or viewing device, thereby rendering adjuvant or explanatory notation invisible; and v) repeating steps ii through iv as needed or desired.

DETAILED DESCRIPTION

[0045] FIG. 1 depicts a portion of the first page 1 of a Jewish Talmud tractate. The Hebrew lettering and words on the page are generally without vowels, though some are shown at 3 in the form of diacritical marks such as dots and dashes underneath or adjacent the Hebrew letters. A Talmudic scholar is expected to understand the nature of the missing vowels. However, a novice or beginning student is generally at a loss regarding the nature of the vowels which can often determine or change meaning. In accordance with the invention, the page is printed with a stencil or other positioning location methods, with invisible ink in the form of the missing vowels. If the ink is UV-sensitive, it is made temporarily visible by UV light such as shown at 2 or is visible with an appropriate lens.

[0046] In addition to missing vowelization, the Talmud, for non Hebrew or Aramaic knowledgeable students, is often cryptic without translation. Accordingly, there are many interlinear or other types of translations currently available in texts. These, however, often serve as a learning crutch without the ready imparting of actual independent understanding. Accordingly, as illustrated in FIG. 2, the Hebrew text is provided with vowels 4 and translations in invisible ink which are ephemeral (only visible with UV light or an appropriate lens) whereby, once the vowels and translations are digested, they are removed until the student is able to know and understand the vowelization and translation, without textual assistance.

[0047] In other applications, as shown in FIGS. 3A-C and 4A-B (in a simplified basic form), an equation 10 is provided with invisible ink made visible to illustrate real objects such as the apples 11 in FIG. 3A which are cumulated (in the addition shown) and with the answer 14 shown in FIG. 3B.

[0048] FIGS. 4A and 4B show, when subjected UV light or under a special lens (depending on the invisible ink used) grammatical and spelling corrections to sentences at 15, 16 and 17 41, curly hair 42, as an answer to the question posed in FIG. 4B,

[0049] FIGS. 5 and 6 show other applications wherein a normally blank sheet of paper 40 is hit with UV light or is viewed under a proper lens (depending on the invisible ink type used) to expose fanciful face 45 with outline 41, curly hair 42, eyes 43 and mouth 44, all of which remain visible for tracing a permanent picture thereon. FIG. 6 depicts a sheet 50 with a visible maze 51, wherein a UV light or special lens makes visible 52 which solves the maze.

[0050] Examples of viewing devices (either by making invisible UV ink visible or by direct viewing with a special lens) are shown in FIGS. 7A through 8B. A book 100 is shown in FIG. 7A with a directly connected UV flashlight 101 with connection 101. The book 100, contains text or pictures with invisible markings which become visible under the UV light of flashlight 101. These invisible markings provide explanations or reading help and the like on a temporary basis as long as the UV light shines on the invisible markings (and possibly for a few seconds thereafter). FIG. 8B shows UV light 201 fixed by an adjustable goose neck connection 204 to book stand 200. UV light 201 is thereby adjustably movable to direct juxtaposition on a paper sheet or book placed on the book stand 200 to light up and make invisible markings viewable, as needed. Lens element 203 of lens 205 in FIG. 8B is fixed to weighted base stand 206 by adjustably positioned goose neck 202.

[0051] Special viewing lenses 103, 105 and 203 in FIGS. 7B, 7C and 8B are used to view specially viewable invisible markings. Round lens 103 and handle 102 in FIG. 7B is similarly connected by connector 101 to book 100. The round lens enables viewing of invisible ink in specific areas of the book text. The elongated lens 105 in FIG. 7C (as well as the lens 203 in FIG. 8B) enables full line or paragraph viewing.

[0052] In FIG. 9A, the Hebrew text of FIG. 2 is provided with a dark area 300 comprised of dark heat sensitive ink 301 with writing 302 (visible in FIG. 9B) camouflaged therein (shown in slight outline for illustrative purposes) and not normally visible. With a heat source, shown as thumb 303, in FIG. 9B being applied to the heat sensitive ink 301, the camouflaged or obscured writing becomes temporarily visible.

[0053] It is understood that the above description and drawings are only illustrative of the invention and that changes in materials and application may be made without departing from the scope of the invention as defined in the following claims.
