Description:FIELD OF THE INVENTION
[001] The present invention relates to the field of augmented reality, and in particular to a method for adjusting the position and size of three dimensional (3D) objects in augmented reality environment for enriching visibility experience.
BACKGROUND OF THE INVENTION
[002] Augmented reality (AR) is an interactive experience that combines the real world and computer-generated three dimensional (3D) content. Further, the augmented reality technology has advanced significantly, it still faces technological limitations that can affect user experience. Issues such as limited field of view (FOV), lower resolution, and latency in AR devices can detract from the immersive experience, causing disorientation or discomfort for users. These limitations also impact the accuracy and realism of AR applications, which are critical for applications in areas like education, healthcare, and professional training. As the technology continues to advance, addressing these limitations will be critical in expanding the applicability and user adoption of AR.
[003] Typically, the ray casting is an image rendering of 3D objects and scenes because a line transforms to a line. So, instead of projecting curved edges and surfaces in the 3D scene to the 2D image plane, transformed lines (rays) are intersected with the object (106)s in the scene. Further, in the ray casting the object is typically positioned at a hit point. Further, the hit point is obtained by the intersection of the extended ray and the scene. Thereby, the object by default placed at the hit point irrespective of the dimensions of the object to be placed in the augmented reality environment.
[004] Sometimes the object is too small or too large resulting hampering visibility of the user when placed on the hit point. But in typical augmented reality devices the placement of the object on the hit point is fixed and the user has no control for positioning the object at the optimum distance in order to maintain visibility and experiencing true or realistic appearance of the object. For example if the object is small like a phone, smart watch etc and being place the object at a point that is far from the camera, such as a small bottle placed 1.5m to 2 m away from the camera. The bottle appear so small that it would not add any value to user experience.
[005] At present, the augmented reality systems face limitations in effectively representing small 3D objects when placed close to the user, often resulting in suboptimal user experiences. Traditional approaches may compromise the user's line of sight or fail to convey the desired proximity effect.
[006] The prior art US10235810B2 titled “ Augmented reality e-commerce for in-store retail” discloses about the augmented reality e-commerce may maximize limited physical space within a store by providing virtual displays of products in predetermined physical spaces. A virtual shelf blueprint that includes positional information for virtual display locations on a virtual shelf may be received. Subsequently, geospatial sensor scans of multiple reference markers in a real-world may be received. The multiple reference markers may correspond to reference points in the virtual shelf blueprint. The virtual shelf may be mapped to the real-world based on the multiple reference markers, in which the mapping may be performed by assigning positional data of the multiple reference markers to the reference points in the virtual shelf blueprint. The virtual shelf may be populated with one or more 3-dimensional (3D) objects that virtually represent at least one real-world product for viewing via an augmented reality device.
[007] Another prior art US11403829B2 titled “Object (106) preview in a mixed reality environment” discloses about images or renderings of items placed (virtually) within a physical space. Further, users can view images or renderings of items placed (virtually) within a physical space. For example, a rendering of an item can be placed within a live camera view of the physical space. A snapshot of the physical space can be captured and the snapshot can be customized, shared, etc. The renderings can be represented as two-dimensional images, e.g., virtual stickers or three-dimensional models of the items. Users can have the ability to view different renderings, move those items around, and develop views of the physical space that may be desirable. The renderings can link to products offered through an electronic marketplace and those products can be consumed. Further, collaborative design is enabled through modeling the physical space and enabling users to view and move around the renderings in a virtual view of the physical space.
[008] The aforesaid prior art are not solving various challenges with respect to positioning of the object in the augmented reality environment as per the user requirement and the size of the object thereby, enhancing visibility of the object.
[009] In order to overcome the challenges associated with the state of art, there is a need for development of a method which is adaptable to position the object in the augmented reality with respect to size of the object in order to improve visibility and to provide uninterrupted line of sight.

[0033] Accordingly, the present invention relates to an augmented reality (AR) system and method for enhancing user experience during the placement of three dimensional (3D) object (106). The augmented reality (AR) system and method is capable of optimizing the display of virtual object (106) in an augmented reality (AR) environments, specifically focusing on object (106) size and distance to the user.
[0034] The present invention introduces a novel method for determining the optimal placement of three dimensional (3D) objects in the augmented reality, taking into account both the size and distance of the object relative to the user. When the size and distance fall below a predefined threshold, the system dynamically selects a stool-based placement strategy. This strategy involves situating the virtual object on a virtual stool, aligning it with the user's line of sight while maintaining the perception of proximity.

If the calculated parameters meet the predefined criteria, the system triggers the stool-based placement mechanism. The virtual stool is strategically positioned to ensure that the 3D object appears close to the user, creating a realistic and immersive visual experience without obstructing the user's line of sight.
[0037] In an embodiment, the processor may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor.

For example, the programming for the processor may be processor executable instructions stored in the memory and the hardware for the processor may comprise a processing resource (for example, one or more processors), to execute such instructions.
[0038] Figure 1 illustrates a flow chart for a method (100) rendering augmented reality e-commerce for optimizing the display and placement of items, comprising following steps-
[0039] At first step, an augmented reality environment is established by casting a ray (104) from an origin point.
[0040] At second step, an object (106) is analyzed, by the processor, for calculating dimension of the object (106).

[0042] At fourth step, the object (106) is placed at the optimum position (108, 110, 112).
[0043] At fifth step, height of a virtual box (114) is calculated with respect to the placement of the object (106) on the ray (104).
[0044] At sixth step, the virtual box (114) is added at a base of the object (106).
[0045] At seventh step, the position of the object (106) is adjusted as per the user requirement.
[0046] In an embodiment, the device is placed at a position where the augmented reality environment required to be developed. Further, the processor activates the image capturing unit on command of the user. Further, the image capturing unit extend the ray (104) in order to generate the augmented reality environment. Further, the ray (104) is originated from an origin point. Further, the origin point is selected by one or more ways. Further, the one or more ways may include but not limited to user selected, dynamic selected and static selected. Further, the dynamic selected and static selected origin point is selected by the processor. Further, the processor execute the instruction for the origin point selection.
[0047] Further, the processor analyses dimension of the object (106) to be place in the augmented reality environment. Further, based on the dimension of the object (106) the processor positioned the object (106) in order to maintain visibility and line of sight from the user. Further, the processor placed the object (106) at optimum location from the user in the augmented reality environment. Further, the position of the object (106) may be adjusted but the size of the object (106) may be reamined same as original size. Further, the device include but not limited to mobile phone, laptop, personal computers, tablet. Further, the object (106) may be extensively placed around the arc, as shown in figure 2.
[0048] Further, the virtual box (114) is placed at the bottom of the object (106) to eradicate the hanging object (106) experience of the user. Further, the virtual box (114) may include but not limited to a square, rectangular, cylindrical and triangular shape. Further, the shape and size of the virtual box (114) may be adjusted to fulfill the purpose of the cross selling. Further, the size of the virtual box (114) may adjusted as per the object height from the base surface. Further, the base surface may include but not limited to a wall and a ground.
[0049] Further, the processor estimate the dimension of the object (106) to be placed in the augmented reality environment. Further, the processor calculate the optimum distance for placing the object (106) in the augmented reality environment by utilizing field of view of the image capturing unit, as shown in figure 3. Further, the processor calculates the optimum distance distance using equation (1) and equation (2).
val maxOf = Diagonal_width / 2
val minimum Distance = max Of / tan(Math.to Radians (camera Horizonal Fov))
[0050] Figure 4 illustrates the object (106) placed at the optimum position including the first position (108). Further, the first position (108) may be an ideal position.
[0051] Further, the object (106) is placed at the optimum position including a first position (108), a second position (110) and a third position (112) based on the optimum distance including a first distance calculated through the equation (1) and (2). Further, the processor calculates the height of the virtual box (114) to be placed below the object (106). Further, the processor calculates the height of the virtual box (114) with respect to the optimum position including a first position (108) of the object (106) which is placed in the augmented reality environment. Further, the user may adjust the position of the object (106), on the ray (104), as per the requirement.
[0052] Figure 5 illustrates the object (106) placed at the second position (110) in the augmented reality environment. Further, the second position (110) is closer to the device (202). Further, the user may commands the processor to move the object (106) in the second position (110) in case the user wants to see the object (106) closer than the first position (108). Further, the processor repositioned the object (106) to the second position (110). Further, the processor calculates the height of the virtual box (114) as per the second position (110). Further, the height of the virtual box (114) increased than the virtual box (114) placed at the first and the third position (108, 112).
[0053] Further, the virtual box (114) is added at the base of the object (106) positioned at the second position (110). Further, the dimension of the object (106) does not change and remains as the original dimension thereby, enhancing user’s experience.
[0054] Figure 6 illustrates the object (106) placed at the third position (112) in the augmented reality environment. Further, the third position (112) is farther to the device (202). Further, the user commands the processor to move the object (106) in the third position (112). Further, the object (106) is placed on the third position (112) when the user wants to see the object (106) farther from the first position (108). Further, the processor repositioned the object (106) to the third position (112). Further, the processor calculates the height of the virtual box (114) as per the third position (112). Further, the height of the virtual box (114) decreased to keep the object (106) scale intact and at the line of sight.
[0055] Also, in figure 5 and figure 6 in combination illustrates the user actions involve the observation of the product from varying distances, rather than the ideal distance. For instance, in figure 4, although the object is positioned at the optimal distance, users may still desire to assess the product from closer or farther perspectives. Further, the user may explore adjustments to accommodate proximity and distance along the ray (104). While the size of the object remains constant, the height of the stool may be adjusted relative to the distance from the ground and the object's position along the axis and/or ray.
[0056] Further, the virtual box (114) is added at the base of the object (106) positioned at the third position (112). Further, the dimension of the object (106) does not change and remains as the original dimension thereby, enhancing user’s experience.
[0057] Further, the processor compare the calculated distance with a distance of the hit point. In case, the calculated distance is greater than the distance of the hit point than the processor placed the object (106) at the hit point, as shown in figure 7. Further, the ray (104) is extended to intersect with opposing surface on the 3D reconstruction and intersect with the opposing surface. Further, the intersection point is known as the hit point. As an extended functionality, as per the user analysis and adopt dynamically the way FSN/SKU’s or objects are placed that are of smaller size.
