DETAILED DESCRIPTION
This disclosure relates generally to puzzles and puzzle games. More particular, this disclosure relates to a puzzle device that creates 3D effects and methods of using the device.
Specifically, the embodiments described herein are directed to a 3D playing device that includes a play surface, at least one anaglyph image displayed on the play surface, a plurality of prearranged dots, and indicia indicating a predetermined sequence to connect the dots. The anaglyph image helps provide a background or foreground for an image gradually revealed by connecting the dots, thereby enhancing the artistic appeal of the playing device.
References are made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration of the embodiments in which the devices and methods described herein may be practiced. The term “anaglyph” refers to an image consisting of two slightly different perspectives (for example, right and left eye views) of a same object in different colors that are superimposed on each other, producing a 3D effect when viewed through two correspondingly colored filters.
The terms “above,” “on,” “under,” “top,” “bottom,” “up,” “down,” “horizontal,” and “vertical” and the like used herein are in reference to the relative positions of the playing device, the playing kit, and their constituent parts, in use when oriented as in FIGS. 1A-F and 2-10.
With reference to FIGS. 1A-F and 3, a 3D playing device 10 includes a playing surface 12 capable of receiving and displaying information, including colors, shapes, size, and images, and colored filter glasses 14 for viewing stereoscopic 3D effects of images displayed on the playing surface. The playing surface 12 shows at least one anaglyph image 20, a plurality of prearranged dots 16, and indicia 18 that indicates a predetermined sequence to draw a line to connect the dots. In one embodiment, the playing surface 12 is a paper playing surface. In an alternative embodiment, the playing surface is an electronic display playing surface. With reference to FIG. 1C, a first anaglyph image 20 is displayed on the playing surface 12. A second anaglyph image 22 is displayed on an outer side of the first anaglyph image 20, as shown in FIGS. 1A-B and D, and a third anaglyph image 24 is also displayed on the playing surface 12, as shown in FIGS. 1A-B and E.
In one embodiment, a base anaglyph image 26 that includes a repeated pattern is also displayed on the playing surface 12. The base anaglyph image 26 helps provide a more solid background and as a result, helps enhance the 3D effects of the playing device 10. In the exemplary embodiment as shown in FIGS. 1A-B and 1F, the base anaglyph image 26 includes a diagonal grid pattern having lines oriented at 45 degrees with respect to a horizontal direction. The line spacing in the diagonal grid pattern is 1.5 mm and the line weight in the diagonal grid pattern is 0.1 mm. It is to be understood that the orientation of the lines in the grid pattern and the spacing of the lines in the grid pattern can vary as desired. It is also to be understood that the base anaglyph image can include any types of pattern, such as waffled pattern, honeycomb pattern, etc.
As illustrated in FIGS. 1A-E, each anaglyph image 20, 22, 24, 26 displayed on the playing surface is made up of a first color layer 30 and a second color layer 32 which are superimposed but offset with respect to each other to create an illusion of depth. The first and second color layers 30, 32 are offset laterally, corresponding to the lateral offset of a viewer's left and right eyes, respectively. When viewing through the colored filter glasses 14, the anaglyph image contains two differently filtered colored images, one for each eye. The anaglyph image allows a left eye to see only the first color layer 30, and the right eye to see only the second color layer 32. The offset between the two color layers 30, 32 in the left and right eyes, respectively, provides an illusion of a parallax, and as a result, create the illusion of depth. The sense of perspective with respect to the playing surface 12 is produced by the degree of offset of the two colored layers 30, 32 viewed by the two eyes. The greater the degree of offset, the more distant the image is viewed with respect to the playing surface 12.
With reference to FIGS. 1A-C, the first anaglyph image 20 is viewed as having a first distance behind the playing surface 12. With reference to FIGS. 1A-B and D, the second anaglyph image 22 is viewed as having a second distance that is greater than the first distance 34 behind the playing surface 12. With reference to FIGS. 1A-B and E, the third anaglyph image 24 is viewed as having a third distance ahead of the playing surface 12. With reference to FIGS. 1A-E, the first and second anaglyph images 20, 22 form a background for the playing surface 12, and the third anaglyph image 24 forms a foreground for the playing surface 12. With reference to FIGS. 1A-B and F, the base anaglyph image 26 is viewed as having a fourth distance behind the playing surface 12, and also forms a part of the background for the playing surface 12.
Each anaglyph image 20, 22, 24, 26 is produced by drawing each anaglyph image in a first color, for example, red, as the first color layer 30, and then drawing a second reproduction of each image in a second color, for example, blue, as the second color layer 32, which is on top of and offset laterally to the left of the red image by a predetermined distance. As a result, the parallax provides the desired illusion of depth, between each anaglyph image 20, 22, 24 and 26, and the playing surface 12. As shown in FIGS. 1A-B and E, the third anaglyph image 24 appears closer than the playing surface 12. In such a case, the red outline in the first color layer 30 is offset, for example, to the left of the blue outline in the second color layer 32; while in the images which are to appear behind the playing surface 12, the red outline in the first color layer 30 is drawn to the right of the blue outline in the second color layer 32. That is, the first and second color layers 30, 32 in a background anaglyph image and in a foreground anaglyph image are shifted laterally in opposite directions. By varying the degree of parallax, various images, for example, the first, second and third anaglyph images 20, 22, 24, and the base anaglyph image 26 can be made to appear at different distances behind or ahead of the playing surface 12. The largest offset produces the greatest impression of depth. For example, among the first, second, third anaglyph images 20, 22, 24 and the base anaglyph image 26, the largest offset between the first and second color layers 30, 32 occurs in the second anaglyph image 22. This largest offset produces the greatest distance between the second anaglyph image 22 and the playing surface 12.
Anaglyph images can be viewed with any stereoscopic viewing technology such as colored filter glasses, polarized filter glasses, side-by-side viewers, etc. In the exemplary embodiment as shown in FIGS. 2-5, colored filter glasses 14 are provided to view the anaglyph images. Typically, colored filter glasses 14 have a red filter 42 contained within a left eye opening of the colored filter glasses and a blue filter 44 contained within a right eye opening. The filters 42, 44 operate as a lens through which the user will view the anaglyph images 20, 22, 24, 26 contained on the playing surface. The red filter 42 allows only the blue part of the image through to the left eye while the blue filter 44 allows only the red part of the image through to the right eye. Each eye therefore sees a slightly different perspective of the image. The brain blends together the images it receives from each eye and interprets the differences as being the result of different distances. It is to be understood that other colors can be used for the filters 42, 44 as desired.
When the two-color anaglyph is viewed through the colored filter glasses 14 having one red filter 42 and one blue filter 44, the viewer's left eye will see only the red outline in the first color layer 30 and the viewer's right eye will see only the blue outline in the second color layer 32, and the varying degree of parallax between the images in the first and second color layers seen by the two eyes produces the illusion of depth or perspective.
With reference to FIG. 1B, the plurality of prearranged dots 16 are arranged such that when the user draws a line from a dot to a dot according to a predetermined rule, an image 50 is gradually revealed. In one embodiment, the predetermined rule is expressed by consecutively sequenced indicia 18, for example, numbers or letters, to indicate the sequence on how the plurality of dots 16 are to be connected. In one embodiment, the image 50 made by connecting all the dots 16 is an image of a complete object. In another embodiment, colors can be filled in the image 50 to enhance the artistic appeal of the image. In one embodiment, colors filled in the image 50 can help reinforce the 3D effect. In the exemplary embodiment as shown in FIG. 1B, the plurality of prearranged dots 16 are located in a center portion of the playing surface 12. However, it is to be understood that the plurality of dots can be located in other locations on the playing surface 12 as desired.
With reference to FIGS. 2-6, a playing kit 100 includes a bound book 110 having a plurality of playing surfaces 12, a carrying case 120 containing colored filter glasses 14 and a permanent marking device 130, and a set of instructions on how to use the playing kit 100. In one embodiment, the playing kit 100 also includes a temporary marking device, for example, one or more soft black pencils, an eraser and a pencil sharpener. In one embodiment, the playing kit 100 also includes markers of colors for filling colors in the image 50 revealed by connecting the dots 16.

In the exemplary embodiment as illustrated in FIGS. 2-6, each sheet 112 includes a weakened area 115, for example, taking the form of score lines, score-slit lines, perforation lines, or the like to allow sheet 112 to be manually detached from the bound book 100 along a longitudinal edge of the sheet 112. The bound book 110 also includes a binding mechanism 114. In the exemplary embodiment illustrated in FIGS. 2-6, the binding mechanism 114 includes spiral binding, thereby allowing the sheets to rotate substantially around the entire binding. In an alternative embodiment, other types of binding mechanism can be used, such as, but not limited to, stapled binding, glued binding, ring binding, coil binding, wire binding, thermal binding, stitched binding, etc. In still another embodiment, the binding can be selected to allow sheets to be added to or removed from the bound book, such as by using openable metal or plastic rings inserted through holes in a book page. In a further embodiment, the plurality of sheets 112 are not bound, but merely maintained in a packaging or container in a loose sheet form. In the exemplary embodiment as shown in FIG. 5, the bound book 110 includes a fold-out sheet 117 to provide a larger playing surface 12. Each fold-out sheet 117 can be folded along a fold line 119.
As shown in FIGS. 2-6, the carrying case 120 has a storage volume sized to enclose therewithin and allow removal therefrom at least colored filter glasses 14, and possibly marking devices, for example, the permanent marking device 130.

The removable clear cover 124 is retained to the base 122 by interference fit, and can be lifted by grasping the cover between a user's thumb and fingers. The carrying case 120 is configured to allow the clear cover 124 to be put back on the base 122 and secured to the base 122 after use. It is to be understood that the carrying case 120 can be in other shapes and can be made of other materials as long as it can releasably contain the colored filter glasses or other accessories. The carrying case 120 is retained to an inner side of the back cover 118 of the bound book 110 by a retention mechanism. In the exemplary embodiment as shown in FIGS. 2-6, the carrying case 120 is retained to the back cover 118 by double-stick tape. Also, in the exemplary embodiment as shown in FIGS. 2-6, the carrying case 120 is retained on the inner side of the back cover 118 along a top edge of the back cover 118. When the playing kit 100 is displayed for retail, the carrying case 120 and the colored filter glasses contained therein are visible to the consumer, as shown in FIG. 2.
As shown in FIGS. 2-6, a permanent marking device 130 is a dark pen or dark marker that can produce a stroke that has a stroke weight that is equal to or greater than a stroke of the background or foreground anaglyph images to facilitate the viewer's eyes to focus on the image 50 revealed by connecting the dots 16. In one embodiment, the permanent marking device 130 is a dark felt-tip pen.
In some embodiments, the playing kit can further include a set of instructions contain suggestions as to the manner how the plurality of dots 16 are connected.
