An Augmented Reality application for Jewelry Shopping

Developing an augmented reality-based application to place virtual replicas of objects instead of real jewelry in jewelry shops. A virtual object is superimposed on some target that appears to be a real one. The user has to wear a marker (different for the corresponding item), and that particular item will be superimposed onto that. By utilizing ICP calculation, the recreation of 3D items is conceivable. The item will be overseen itself as indicated by the client continuously by utilizing HAAR. Payment integrations, user authentication, and order functionality have been integrated to make this app as competitive as other e-commerce applications.

Whereas, marker-less AR works by scanning the environment. There is no need for a marker or trigger photo, or target marker. Apps with such functionality demand a flat surface like a table or floor for placing the AR element else, the object will look like floating in the air. This Virtual Jewellery Shopping Application works on Marker-based AR. The app scans the marker using a phone camera. This will serve as a marker to show the desired entity. It uses the Vuforia engine to scan markers and place objects.
Vuforia is used for feature extraction because it delivers a robust and precise AR experience in various environments. Each jewelry type has a unique marker. It helps to differentiate among the various jewelry types. SLAM: This makes it feasible for AR applications to Recognize 3D Objects and Scenes, just as to Instantly Track the world and to overlay advanced intelligent increases. SLAM uses EKF Algorithm.

Implementation
The Implementation of the application is a process of seven different steps : 1. User Authentication 2. Generation of the marker 3. Choosing the right article 4. Projecting the article on the marker 5. Adding the selected item in the cart and entering other details. 6. Making a payment using Razorpay 7. Order status functionality 8. Let's discuss these steps one by one : • User Authentication: It is the initial and most essential step of the process.
• To Try out the application and to proceed further, customers have to log in first. Users have to enter the credentials to login into the application.  To try any article on themselves, users need to download the marker first according to their size. A marked image that has almost every size is given in the application only. Marker [1][2] is chosen based on feature points it contains, i.e., Unique features that each image has in the form of edges, spots, or curves that look the same when observed from different angles. For selecting the markers, we have used a tool called Vuforia, which is used for feature extraction from an image and delivers robust and precise Augmented reality experience in various environments [3]. Vuforia gives the star rating out of 5 based on patterns present in the marker. Some of the markers we have used are given below. There is a lot of software available for designing 3D objects, and we have used Maya and Blender 3D for this project. For trying an article, you have to choose that particular item and then wear the requisite marker on that part. Some of the articles in the application are given below:  • Adding the selected item in the cart and entering other details: After selecting the desired articles, users can add them to the cart for ordering. We have added the cart functionality to our application. • Customers can add their products to the cart using the "Add To Cart" button.
Customers can check their chosen items in the cart and can place orders using the same. • Making payments using Razorpay: We have integrated Razorpay into our application for payments. Razorpay allows users to pay virtually. • Customers can place orders and make payments using Razorpay.
Users can make payments using any online method, including net banking, UPI, credit, and debit cards. • Customers can track their orders in real-time.
• All the orders will be displayed in the My Orders section of the application.

AR Technology Today
Some of the applications of AR in different industries are : A. Education: B. When new technologies are made, tries are consistently made to evolve them for educational and informative settings. Augmented reality is no particular case, and for more than ten years, AR headway has endeavored in various diverse instructive applications. These preliminaries have shown that AR can be more helpful and simple for understudies to learn and comprehend the ideas without any problem in explicit conditions.
With AR, homeroom training can be remarkable and more intuitive. AR can empower instructors to show virtual ideas and add gaming components to offer course reading material help. This will empower students to learn quicker and remember data. Some examples of such applications are: • An AR application, called "Dinosaur 4D+", with many cheat sheets empowers clients to see 3D dinosaurs looking over the card. With this, students can see the activities of dinosaurs and use application highlights to pivot, zoom, and the sky's the limit from there. Plus, the application additionally gives some data about every dinosaur. • The "Element 4D" AR application is another good illustration of Augmented Reality in schooling, making learning science fun. The application empowers users to track down the nuclear weight, compound components, the response between two synthetics, and their names by basically putting two paper 3D squares for an extraordinary component block. • Another appreciated illustration of AR/VR in training is "Google Expeditions", which empowers users to see 3D items in the homeroom, for example, volcanoes, storms, and even DNA. This application gives more than 100 AR campaigns that incorporate the historical backdrop of innovation, the moon landing, and then some more. Augmented Reality is an optimal development for setting virtual information superimposed over the current reality. As such, it will, in general, be used to handle conceivably the fundamental issues in design i.e., you can see whatever hasn't been assembled at this point [7], [8], [9].
For the most part, creators used an extent of different devices to show their clients what their constructions will take after, including 2D plans, genuine models, 3D renderings, wise walkthroughs, and vivified flythroughs. In any case, there are various insufficiencies with these systems. For example, 2D plans can show the arrangement of a design comprehensively, however at this point and again, the client encounters trouble imagining what the construction would look like from the 2D drawing. Genuine models, 3D renderings, and insightful fly-throughs help the client get what the construction looks like; in any case, they are a diminished scope interpretation of the first space. These may not reflect a sensible appreciation of what the design will take after full-size on the first region. Increased Reality can be used to see full-sized 3D virtual models of future designs on the destinations where they will be manufactured. This allows those propelled by design to appreciate what it will look like. Moreover, the application could be used as an orchestrating gadget, putting a couple of types of comparative construction on the site and allowing the client to give input about the particular arrangement decisions.  [6], AR has been utilized successfully in PR and advertising drives for movie, TV, and other media special missions. Regularly, these have included printed realistic or genuine item acknowledgment where the product distinguishes a unique image using a webcam or phone camera. G. Examples of such applications are: H.
• REAL STRIKE: This is a mainstream shooting AR game that is accessible just on iOS. The users get a genuine shooting experience in this game and record their battles and make their recordings. A pool has been dirtied by atomic waste, and a gathering of vermin is not far off, so players need to prevent them from contaminating the earth. Clients utilize their telephone to filter the imprint. The game offers night and warm vision goggles to get an excellent view to finish your central goal, even in the evening.
Received: October 26, 2020 Accepted: July 01, 2021 70 There was a steep decline in searches for Virtual Reality. Then, at that point, in 2009, the hunt pace of Augmented Reality rose, passing the Virtual Reality look and turned out to be twice as famous continuously.
This was mainly because of the main three factors: 1. Flash-based AR 2. AR compatible Smartphones 3. Adoption of AR in global marketing campaigns. [5] All these factors altogether drove billions of people to have had the AR technology experience. In June 2013, VR again ignored AR since Oculus Rift and other modest HMDs showed up with Virtual Reality. In 2008, the Flash platform gave rise to Flash-based AR, when Adobe added camera support to its popularity. The ARToolKit library was ported to Flash, creating FLARToolKit by a pair of Sqoosha and Nyala. This was the first time, within their web browsers, people could have an AR experience. This led to a large number of web-based AR applications. The rise of smartphones was the second important factor.
Because of slow graphics power, slow processing, and limited sensors, it was challenging to develop. Still, the iPhone launch in 2007, with a fast processor for real-time computer vision tracking and powerful 3D graphics, provided a platform that was easy to develop. In October 2008, the first Android phone provided a significant boost to mobile AR. Qualcomm's Vuforia19, ARToolKitand authoring tools like BuildAR20 make it non-programmers possible to create AR experiences. 42.9 million people are willing to use VR, and 68.7 million people can use AR at least once per month.

Conclusion
The application that we've developed brings about a fresh approach towards augmented reality. It accredits the buyer to scrutinize the product to a greater extent. The foremost step is to log in with the user credentials, which guarantees identity security. Coming to the spellbinding feature of our application, the size-based marker generation process. After generating the marker, the user can bounce to the available articles categories, including watches, rings, and earrings. After choosing the article, the customer will be able to browse the designs available, and that's where augmented reality comes into projection. To access the try-on feature, the users will have to project the marker on the desired part, which will result in the projection of the desired article.
Along with that comes the 'Add to cart feature, where the user can directly add the article(s) into their cart while the item is being projected. Eventually, users are directed to the Razorpay payment gateway. Customers have also been provided with the competence to track their orders' status in the 'My Orders' section of the application.
