Description

FIELD OF TECHNOLOGY

[0001] Embodiments in accordance with the present invention generally relate to a security device suitable for use in providing enhanced security to high value industrial products by endowing said high value industrial products with at least one of an aesthetic effect or an authenticating effect when they are attached to him. In some embodiments, the optical security device comprises an arrangement of microimage elements positioned relative to the focusing element arrangement such that the microimages or portions thereof project one or more artificially generated images when the microimages or portions thereof are viewed through the focusing element arrangement or portions thereof. This security device provides at least one dynamic optical effect, as a result of which at least one of the artificially created images projected by the device appears for the observer to be transformed - relative to at least one of its shape, location, color or size - when changing the observer's point of view. In particular, the dynamic optical effect is an interactive dynamic optical effect, wherein the optical effect is accompanied by at least one targeting effect or includes at least one targeting effect. The targeting effect includes the interaction of two or more targeting images - at least one of which is one of the artificially generated images - that appear for spatial coordination to reveal at least one reward image. For example, when the dynamic optical effect is a location transformation of an artificially generated image, at least two targeting images spatially interact with each other such that a reward image is revealed at predetermined relative locations.

[0002] Embodiments in accordance with the present invention include methods for making a security device, methods for using a security device, methods for protecting high value industrial products with a security device, methods for making secure high value industrial products, and products made through the processes described in this document.

BACKGROUND OF THE INVENTION

[0003] There are several types of optical security devices. For example, optical security devices are described and shown in US Pat. Nos. 7,333,268; 7,738,175 and 7,468,842, in which one or more artificially generated images are projected by a security device.

[0004] Although there are several optical security devices that are suitable for providing increased security to various industrial products, they are often “level 1” security features (for example, visible to the user) that require the end user to visually investigated the built-in security device to authenticate the industrial product to which it is attached. However, such devices suffer from intrinsic dynamics in the way such industrial products are used. For example, although banknotes are often protected (aestheticized and/or authenticated) by such security devices attached to them, the effectiveness of such security devices depends on the interaction of the end user with the security device. However, due in large part to the rapid pace of use, end users of banknotes and other similar industrial products are often left out of the authentication process in the sense that they quite often use banknotes without authenticating banknotes by actuating a security device.

SUMMARY OF THE INVENTION

[0005] Some embodiments in accordance with the present invention provide a security device that improves end-user interaction with security devices and end-user use of security devices designed to protect high-value industrial products. Such security devices, in turn, would enhance the effectiveness of the security device as a level 1 security device, thereby discouraging tampering.

[0006] Security devices in accordance with various embodiments of the present invention provide functionality that encourages users to operate the security device or interact with the security device. Thus, the end user not only interacts with the artificial image or dynamic optical effect, but also interacts with the interactive dynamic optical effect (i.e., the targeting effect), as a result of which the end user's intelligence is challenged and rewarded. In particular, in some embodiments, the implementation of the security device contains a game that allows the end user to transform the optical ratio of the target images to obtain/detect the reward image. For example, the end user will be rewarded with a reward image when they succeed in causing the target images to spatially completely overlap, occupy predetermined non-overlapping locations, or partially overlap. Through this interaction, the authentication or aesthetic functions of the security device are utilized more frequently through increased end-user interaction with the security device. By providing, in some embodiments, "gaming" functionality in the security functions of the security device, end users may be more likely to closely monitor the presence and functionality of the security device and, as a result, detect counterfeits more often.

[0007] In one aspect of the present invention, an optical security device is provided. In certain embodiments, the optical security device is a micro-optical security device comprising an image projection system comprising: (i) an array of focusing elements; (ii) an array of image thumbnail elements positioned adjacent to the focusing element array such that at least one artificially generated image is projected by the image projection system when at least portions of the image thumbnail element array are viewed through at least portions of the focusing element array; and (iii) an array of control template elements integrated with all or part of the array of image thumbnail elements; a set of targeting images, at least one of which is one of artificially generated images projected by the image projection system; and at least one reward image. The micro-optical security device is further characterized in that the security device provides a targeting effect such that, in a predetermined alignment phase, the targeting images are spatially coordinated to coincide with the detection of the reward image.

[0008] In various embodiments, the micro-optical security device is further characterized in that the visibility of the targeting images and the reward image(s) is modulated by an array of control pattern elements.

[0009] In some embodiments, in accordance with the present invention, a method for manufacturing a micro-optical security device is provided. In a specific embodiment, a micro-optical security device is created by providing an image projection system comprising an array of image icon elements integrated with an array of control pattern elements and layered with an array of focusing elements such that at least one artificially generated image is projected by the image projection system when at least at least parts of the array of icon elements, the images are viewed through at least parts of the array of focusing elements. The method is further characterized in that the micro-optical security device provides at least two targeting images that are spatially coordinated in a predetermined alignment phase to coincide with the detection of at least one reward image when the in-phase portions of the control pattern element array are in focus of the focusing element array such such that at least one set of reward images is detected. In accordance with some embodiments, a given alignment phase is associated with a given viewing angle or range of viewing angles. In some embodiments, the specified alignment phase exists as a result of the interaction of the controls and image thumbnail elements, but the viewing angle to which the specified alignment is associated is not predetermined or otherwise known in advance.

[0010] In some embodiments, the method includes: (i) providing an array of focusing elements; (ii) providing an array of image icon elements; and (iii) positioning the array of focusing elements and the array of image thumbnail elements relative to each other such that the artificially generated image is projected by the image thumbnail elements when at least portions of the array of image thumbnail elements are viewed through at least portions of the focusing element array. The method is further characterized in that the micro-optical security device provides at least two targeting images that are spatially coordinated in predetermined alignment phases such that the spatial coordination coincides with the detection of at least one reward image. Also, the method is further characterized in that the spatial coordination of the targeting images matches when the in-phase portions of the array of control template elements are in focus of the array of focusing elements. In one or more predetermined alignment phases, the in-phase portions of the array of control pattern elements are in focus and at least one reward image is revealed.

[0011] In accordance with various embodiments of the present invention, the image icon element array and the focusing element array are positioned relative to each other such that the security device provides at least one artificially generated image with a dynamic optical effect that is part of the targeting effect. The targeting effect, as described in various parts of this document, includes the spatial interaction of one targeting image having a dynamic optical effect with another targeting image, which may be another artificially created dynamic optical effect image, an artificially created image with a static optical effect, natural image or selected optical coordinate. The spatial interaction considered herein includes the case where, in a given alignment phase, the targeting images are displayed at a given distance from each other, such as the targeting distance, partially overlapping or completely overlapping, preferably at least partially overlapping. In this predetermined alignment phase, the in-phase portions of the control pattern element array are in focus of the focus element array, thereby revealing (eg, including) the reward image. Preferably, when the reward image is turned on, the targeting images are turned off, and when the reward image is turned off, one or more targeting images are either turned on or off. However, in some embodiments, only part of the target image is turned off or only part of the reward image is turned on, and vice versa. The spatial interaction of the target images can be an overlap of the target images, or placing the target images at a given distance from each other, or changing the size of the target image, or changing the color of the target image, or changing the visible plane (deep, single plane, or floating point).

The micro-optical security device is further characterized in that it is made by: (i) providing an array of focusing elements; (ii) providing an array of image icon elements; and (iii) arranging the array of focusing elements and the array of image thumbnail elements relative to each other such that the artificially generated image is projected by the image thumbnail elements when at least portions of the array of image thumbnail elements are viewed through at least portions of the focusing element array. It is further characterized in that the micro-optical security device provides at least two targeting images that are spatially coordinated in predetermined alignment phases such that the spatial coordination coincides with the detection of at least one reward image. Also, the method is further characterized in that the spatial coordination of the target images matches when the in-phase portions of the array of control template elements are in focus of the array of focusing elements.

[0014] In yet another aspect, a secure industrial product is provided. In some embodiments, the industrial security product comprises: (i) an industrial product and (ii) at least one micro-optical security device. The secure industrial product is characterized in that the micro-optical security device is securely connected to at least one surface of the industrial product in such a way that it is at least partially visible to the end user. In a further embodiment, the industrial security product is characterized in that the micro-optical security device is connected to the industrial product in such a way that the end user can visually operate the micro-optical security device.

In a further embodiment, the micro-optical security device is further characterized in that the image icon element array comprises an array of control pattern elements.

[0015] Other embodiments in accordance with the present invention include the use of a micro-optical security device to authenticate an industrial product. In this document, the micro-optical security device is integrated with the industrial product in such a way that it can be easily operated by the end user of the industrial product.

DETAILED DESCRIPTION OF THE INVENTION

[0032] According to some embodiments, by providing a micro-optical security device having a targeting effect, the end user can modulate the transformation or interaction of the targeting images to reveal at least one reward image, thereby increasing the likelihood of prompting the end user to actuate the security device. Thus, the end user of the security device can turn targeting and/or reward images on or off by changing viewing angles to spatially coordinate the targeting images, and by moving in and out of the viewing angle ranges associated with the alignment phase(s). . To enable targeting and/or reward images means to reveal these images or make these images visible at certain viewing angles, and to disable targeting and/or reward images means to make these images less visible, partially invisible or completely invisible at certain viewing angles. By modulating these targeting effects by the end user, the security device becomes more interactive and more attractive to the end user and therefore more likely to function to protect the manufactured product by authenticating or aestheticizing the manufactured products to which the security device is attached.

[0033] The micro-optical security device, which is herein referred to interchangeably as a security device, comprises an image projection system and displays a set of targeting images and at least one reward image.

[0034] An image projection system, along with a set of targeting images and a reward image, are elements of a security device. This image projection system includes an array of focusing elements that is associated with an array of image icon elements (eg, microimage elements). These linked arrays may be directly layered on top of each other, or may be interleaved with other arrays or layered, or may comprise multiple microimage element arrays or multiple focus element arrays. In various embodiments, an array of image elements is combined with a control template that modulates detection of a reward image, target images, or both. The image projection system either individually provides a set of target images, or provides a less than complete set of target images, which is then combined with a natural image to provide a complete set of target images. In any case, at least one of the target images will be provided by the image projection system. These image projection systems comprise at least one array of microimage elements in the form of image icon elements and at least one array of focusing elements. Image thumbnail elements and focusing elements are co-located with respect to each other such that they cooperate to provide at least one targeting image, which is an artificially generated image projected by an array of image thumbnail elements when at least portions of the image thumbnail elements are viewed through at least part of the focusing elements. It is important that the image projection system contains an array of control template elements located in an array of image icon elements or a part of it. An array of control template elements modulates turning on and off targeting images and reward image(s); in particular, control pattern elements modulate reward image elicitation. In one embodiment, as best illustrated in FIG. 1, the focusing element array (101) and the image icon element array (103) are layered next to each other. At one or more viewing angles, an observer who views the image thumbnail elements sees an artificially generated image that is projected by the security device through the interaction of the image thumbnail elements and the focusing elements. Various embodiments are considered suitable for use as image thumbnail elements and as focusing elements. Suitable picture elements and focusing elements, as well as methods for providing them, are described in international patent applications WO2005/052650, WO2006/125224, WO2008/008635, WO2011/019912, WO2011/163298, WO/2013/028534, WO2014/143980/WO2009 017824; WO2016/044372; WO2016/011249; WO2013/163287; WO2007/133613; In preferred embodiments, the image elements are in the form of cavities, solid areas, protrusions, or any combination thereof. Suitable focusing elements and methods for providing them are described in international patent applications WO2006/125224, WO2008/008635, WO2011/019912, WO/2013/028534, WO2014/143980, WO2016/044372, WO2016/011249, WO2007/132012. , WO2015/148878, WO2017/105504, WO2005/106601 and WO2006/087138, all of which are incorporated herein in their entirety.

[0035] Further, it is also contemplated herein that other components may be added to the image icon element array, the focus element array, or may be added between the image icon element array or the focus element array. Examples of suitable additional components include, but are not limited to, an optical spacer, a coating layer, an adhesive layer, a base embossed photo varnish layer, a patterned metal layer, a reflective layer, an opacifier layer, a vapor deposition layer, a color-changing building layer, an anti-contamination layer, a reinforcing layer; or a pigmented or colored layer. In addition, it is contemplated that a plurality of microimage element arrays or image icon elements are also integrated as part of the image projection system. Likewise, it is also contemplated that a plurality of focusing element arrays are also integrated as part of the image projection system. In addition, it is assumed that the focusing elements are sealed lenses, which are either partially or completely sealed. For example, in certain embodiments, the sealing layer occupies the intermediate spaces between the individual focusing elements, and in other embodiments, the sealing layer covers the entire height of the individual focusing elements and may be formed into focusing elements or may be flat on the side distal to the focusing elements. . In other embodiments, the sealing layer covers the entire image projection system, including the focusing elements and the microimage element array.

[0036] It is also contemplated herein that the image icon element array and the focus element array may be ordered in different sequences. For example, in one embodiment, the array of image thumbnail elements is positioned below the array of focusing elements such that an observer viewing the security device from the first side will view the image thumbnail elements through the focusing elements. In another embodiment, the array of image thumbnail elements is located above the array of focusing elements such that an observer viewing the security device from the first side will see the image thumbnail elements without viewing them through the focusing elements. This document also assumes that the image elements are viewed through a separate array of pinholes that function as focusing elements.

[0037] Various focusing elements and image thumbnail elements are contemplated within the scope of the present invention; many of these, in light of the present invention, will become apparent to PHOSITA. Preferred embodiments are illustrated in Figures 1a-1e. Alternatives are further described in international patent application publication WO 2013/028534, which describes a portable micro-optical system in which image icon elements are essentially embedded in focusing elements; WO 2005/052650 describes a micro-optical security device comprising various image icon elements, focusing elements organized and arranged in various sequences to provide an artificially created image; WO 2013/163287 and WO 2014/039476 also describe a suitable micro-optical security device in which image thumbnail elements are distinguished, image viewpoints are interleaved, different viewpoints are interleaved, and pixels are matched to form image thumbnail elements; WO 2009/017824 describes image icon elements that are a combination of multiple image elements that are stitched together to form a single image icon element; WO 2011/163298 describes focusing elements that are built in; all of which are incorporated herein by reference in their entirety.

[0038] Suitable focusing elements can take various forms and include all elements that can be arranged in an array, where they can be used to both enlarge and condense or combine image icon elements or parts thereof into a composite and enlarged image ( i.e. artificially created image). For example, suitable focusing elements include, without limitation, lenses such as stepped lenses, parallel or transversely streaked, or non-cylindrical lenses or microlenses. Shape, size and any pigment can be chosen to achieve the desired purpose. These lenses can be reflective or refractive. In addition, each of the refractive index, f#, diameter, and shape can be adjusted to obtain a desired optical effect when interacting with image thumbnail elements. The present invention also contemplates that the focusing elements are graded refractive index lenses having a graded refractive index. For example, in FIG. 1a shows printed elements (103) of image icons located in an array on one side of the optical spacer (102) and opposite the array (101) of focusing elements. In contrast, in Fig. 1b shows image icon elements (103) as microimage elements (103) that are formed on/in an optical spacer (102), which may optionally be filled (fully or partially) or covered (fill, image). In an alternative embodiment, the image icon elements may be formed in the optical spacer (102), filled (103), and coated, or may be deposited as a separate layer, as shown in FIG. 1s. The focusing elements themselves can be refractive, reflective, or a combination of both. Or, as shown in FIG. 1d, the focusing elements (104) may be pinholes through which image thumbnail elements can be viewed to project an artificially generated image. In FIG. 1e, focusing elements are provided in the form of an array (101) of reflective lenses located below the array (103) of image icon elements in such a way that an observer located next to the image icon elements (103) can view the array of image elements as a projected artificially created image through reflection an array (101) of reflective focusing elements.

[0039] In certain embodiments, the focusing elements described in various embodiments herein are microlenses. In various embodiments in accordance with the present invention, the microlenses are non-spherical or spherical with a polygonal base and are located in multiple areas of hexagonal arrangements. In certain embodiments, the microlenses are arranged in rectangular, triangular, and other geometrically repeating arrangements. In various embodiments, the microlenses have polygonal, circular, or elliptical bases. In some embodiments, the microlenses have polygonal bases with rounded tops. Applicants have found that embodiments that use a hexagonal layout can effectively increase the resolution of artificially generated images formed by focusing elements and microimage elements. Focusing elements considered to be within the scope of the present invention may be convex or concave.

[0040] The micro-optical security devices described herein comprise an image presentation system comprising an array of image icon elements and an array of focusing elements. The image thumbnails and the focusing elements cooperate to produce an artificially generated image when the image thumbnail elements are viewed through an array of focusing elements.

[0041] The image thumbnail elements are organized into an array that is integrated with the image thumbnail layer. These image thumbnail elements may be in the form of an image, or they may be parts of an image. By interacting with the array of focusing elements, these icon elements are enlarged and composed to form a composite image when individual focusing elements are focused on images or parts of images. In some embodiments, the image thumbnail elements form images through relief structures that are integrated with the image thumbnail layer. Thus, integration used in this context includes introducing an embossed structure into the image icon layer, for example by embossing, or includes applying an embossed structure to the image icon layer, for example, by printing or by applying a cover layer to the icon layer. images and embossing this cover layer with a relief structure representing the image or parts of the image.

[0042] The relief structures forming the image icon elements may be of various sizes, including micro-size, nano-size, macro-size, or any combination thereof. While it is contemplated that nano or macro size would be appropriate, in some embodiments, micro image icon elements are also effective. The inventors have found that such preferred embodiments of icon elements have improved production capability compared to alternatives.

[0043] The relief structures that form the image icon elements may be in the form of recesses, posts, or combinations thereof. When such relief structures are depressions, they may be shallow depressions that end somewhere within the thickness of the image thumbnail layer, or they may be cavities that extend through the image thumbnail layer and abut against one other layer.

[0044] Image thumbnail elements may be formed in a variety of ways, including, for example, laser patterning, photolithography, machining, embossing, printing, injection molding, other molding techniques, or any combination thereof.

[0045] The cavities can be coated in a variety of ways, including, for example, electroplating, chemical deposition, vapor deposition (e.g., chemical and/or physical), monomer vapor deposition, spraying, spin coating, coating with roller, other coating methods and any combination thereof.

[0046] In some embodiments in accordance with the present invention, image icon elements interact with an array of focusing elements to provide an artificially generated image.

[0047] The control template elements are integrated with the image icon element array such that when in-phase arrangement, the target images are turned off and the reward image is turned on. The control template may be of any shape or size desired and positioned such that at a given alignment phase, the device allows the viewer to see the target image, and at another set of preset alignment phases, the device allows the observer to see a set of reward images. This is illustrated in FIG. 3, in which artificially generated images (310), which are targeting images, are viewed from the viewpoint rotated by 10 degrees and separated by a separation distance d. In this illustrative example, a separation distance of less than d will allow the viewer to see the reward images. Since the security device is oriented to the viewpoint with a rotation of 15 degrees, the target images approach a separation distance of less than d, resulting in the inclusion (revealing) of the reward image (320), while the target images (310', 310” ) are off. A similar effect is observed when the targeting images (340', 340") begin to overlap from the 80 degree viewpoint in such a way that from the 77 degree viewpoint they overlap sufficiently for this particular design to produce an image rewards and the reward image (350') is turned on and the targeting images (340', 340”) are turned off.

[0048] The control template as illustrated in FIG. 2a-2d may exist in-phase and/or out-of-phase, depending on the design of the image icon element pattern in the image icon element array. In the illustrative example shown in FIG. 2a, thumbnail images 1 (201) and thumbnail images 2 (202) are components of the image thumbnail element array. In this illustrative example, the components are superimposed on each other. This particular overlap has areas where positions 201 and 202 are in phase or otherwise overlap (204). In some embodiments, the degree to which the overlap is considered in-phase is a design choice. The control template element array (203) can then be further added to the icon element array and superimposed such that it is also in-phase with the previous two components (206). In accordance with some embodiments, this ensures that the control pattern that modulates the appearance of the reward image is in-phase with the image's icon elements such that when the image's icon elements are close enough together, the control pattern will detect the reward image at a particular location. . In the illustrative example shown in Fig. 2a, an award image is generated when "pictogram images 1 (201)" which provide parallax image 1 and "pictogram images 2 (202)" are in-phase with each other for part of their length, and also in-phase with the "windows" of the control template (203). In addition, as shown in this illustrative example, in the region (205), when the thumbnail images (201) and (202) are out of phase with each other, no reward image is visible. Similarly, in the region (204), the thumbnail images (201) and (202) are in phase with each other, as well as with the elements of the control template (203), revealing the reward image. In addition, the control template may be integrated as part of an image icon element array, thus functioning to include an award image. Thus, the control template may itself be filled or coated (FIG. 2c) with a contrast material via an array of cavities, or may be a window (FIG. 2b) through which image icon elements used to project a set of reward images are viewed.

[0049] FIG. 2b illustrates an embodiment in which the reward image is composed of a parallax image (213) that is visible in a predetermined alignment phase through the control pattern "windows" (213). The interaction between the control template (213) and the icon layer elements (225) is illustrated by a line (215). In certain areas, for example, in the area (217), the elements of the control template (213) create empty spaces in the icon layer, while the icon is not visible through the control template. Similarly, in certain areas, such as area (219), the control pattern (213) provides high visibility of the icon layer, for example, providing visibility of a significant number of one or more ink-filled depressions. As shown in the non-limiting example illustrated in FIG. 2b, the icon layer (221) contains two or more sets of icon images, which may be differently in-phase with each other and control template elements (e.g., as shown in area (225)), or be out of phase with each other and elements. control template (for example, as shown in area (223)).

[0050] FIG. 2c further illustrates the operation of the control template (237) in accordance with some embodiments. In various embodiments in accordance with the present invention, the control pattern (237) is not an ink-filled recess, but an element pattern that excludes one or more other patterns (e.g., icon layer pattern (235)), allowing reward image data to be visible through " windows" or "holes" of the control template (237). In the illustrative example shown in FIG. 2c, this exception is illustrated with row (230).

[0051] In one illustrative embodiment, shown in FIG. 2d, a printed element (240) such as a star acts as a target image, so that when another target image provided by the image projection system aligns with the printed star as shown in the area (245), the control pattern (241) and projected the artificially generated images are in-phase, thereby leading to the identification of the reward image. Similarly, when the control pattern (241) and the projected artificially generated image are out of phase (eg, as shown in area (247)), the reward image is not visible.

[0052] As used herein, the term "artificially generated image" refers to an image that is artificially enlarged by an array of focusing elements in two ways. Thus, the focusing elements, when used to view an image icon element array, increase the apparent size of the microimages or portions thereof depicted by the image icon element relief structures. Furthermore, when the image thumbnail element array is viewed through the focusing element array, portions of the image thumbnail element array that are in focus at any given viewing angle are optically combined to form at least one artificially generated image.

[0053] The size of the artificially enlarged image in various embodiments may be modulated by the interaction or selection of a number of factors. For example, as described herein, each of the image thumbnail element array and the focus element array may be individually arranged such that a repeating image thumbnail element pattern, or sets of image thumbnail elements, or a repeating focus element pattern, or a set of focus elements are repeated under selected angle. This selected angle is referred to herein as the skew axis, and this skew axis will run at a certain angle, referred to herein as the skew angle. The amount of artificial magnification may be increased or decreased depending on the degree of crossing of the cross axis of the focusing element array and the cross axis of the image thumbnail array. For example, when both the focusing element array and the image thumbnail array have an identical pattern, slightly shifting their skew axis such that the focusing element array's cross angle is slightly larger or smaller than the image thumbnail array's cross angle can produce a set of artificially generated images that are enlarged versions of the image thumbnail elements, but rotated approximately plus or minus 90 degrees relative to the image thumbnails.

[0054] At least one of the targeting images in accordance with some embodiments of the present invention is an artificially generated image projected by an image projection system; in particular, this artificially generated image is projected by the image thumbnail elements when at least parts of the image thumbnail elements are viewed through at least parts of the focusing element array. Accordingly, the image projection system comprises at least one array of focusing elements; at least one array of image icon elements; and at least one array of control template elements.

[0055] In accordance with various embodiments, targeting images of the security device include at least one artificially generated image projected by an image projection system. For simplicity, this targeting image will be referred to as the main artificial image. In a preferred embodiment, this targeting image provides a dynamic optical effect, also referred to herein as a dynamic effect, whereby this targeting image appears to change location, change color, change size, or change shape as the viewing angle changes. Other targeting images may be selected from an optical coordinate, an optical image, a natural image, or another artificially generated image.

[0056] The targeting images are coordinated such that their appearance is modulated at a given alignment phase. For example, in one embodiment, when the distance between the target images is shortened by changing the viewing angles so that they are very close or they overlap in one or more predetermined alignment phases, at least one of the target images disappears; preferably the whole set. Alternatively, when the color or shape of one of the target images is changed by changing the viewing angles such that a color/shape match occurs in a predetermined alignment phase, then at least one of the target images disappears. In certain embodiments, the entire set of targeting images disappears. In various embodiments, a sufficient number from the set of target images disappears such that the reward image is not obscured by the aligned target images. When the size between the target images is adjusted up or down by changing the viewing angles such that the predetermined size is observed in the predetermined alignment phase, then at least one of the target images disappears; preferably the whole set.

[0057] Targeting images can take on any shape, size, color, or combination thereof. Images referred to in this context include text, numbers, symbols, images, or any combination thereof.

[0058] In some embodiments, targeting images are coordinated to have a spatial interaction that coincides with reward image detection.

[0059] The reward images referred to herein may also take on any shape, size, color, or combination thereof. In addition, reward images are revealed when target images interact spatially as described above. In various embodiments, the entire reward image remains hidden from all viewing angles except for the predetermined alignment phase(s). In some embodiments, only part of the reward image is hidden such that only complementary parts of the reward image are revealed in a given alignment phase.

[0060] The reward image referred to in the context of the present invention includes artificially created images, such as a main artificially created image, or an optical image, or a natural image, such as a printed image. In some embodiments, a reward image that is also a basic artificial image may be effective as a reward image because such images also provide a dynamic effect that further engages the viewer. In some embodiments, the reward image may be a static image that remains hidden until the target images interact in a predetermined manner, such as through spatial interaction, shape interaction, color interaction, size interaction, or any combination thereof.
