Augmented reality solutions have become increasingly popular in recent years due to the emergence of mobile devices equipped with advanced sensors and processors. AR technology overlays digital content on top of the real-world environment, creating an interactive experience that enhances users' perception of reality. When discussing AR solutions there are a few frequently used categorizations for classifying the approach of the technology. We will discuss two of those categorizations in this article, the first of which being: marker-based AR and markerless AR. The second categorization outlined relates to visualization and display: Head mounted displays (HMDs) and mobile devices.

Mobile Augmented Reality Solutions

Marker-based AR solutions use a specific visual marker, such as a QR code, to trigger the display of digital content. The marker serves as a reference point that allows the AR software to align the virtual content with the real-world environment. Marker-based AR solutions have been used in various applications, such as advertising, gaming, and education. One of the companies that have implemented marker-based AR is IKEA. IKEA's AR app allows users to place virtual furniture in their homes using their smartphone camera and the IKEA catalog as a marker.

Markerless AR solutions use computer vision algorithms to track the position and orientation of the device's camera in real-time. This approach enables AR solutions to be used in a wider range of applications, such as navigation, maintenance, and training. One of the companies that have implemented markerless AR is Vuforia. Vuforia provides an AR platform that enables developers to create AR experiences without requiring a specific marker. Vuforia's AR platform has been used in various applications, such as product visualization, retail, and entertainment.

Lens Based Augmented Reality Solutions

A second commonly discussed categorization for AR solutions is based on the display technology: head-mounted displays (HMD) and mobile devices. HMDs are wearable devices that provide an immersive AR experience by overlaying digital content directly onto the user's field of view. Mobile devices, on the other hand, use the device's camera and display to overlay digital content onto the real-world environment. One of the well-known companies to have developed HMDs for AR is Microsoft. Microsoft's HoloLens 2 is a wearable device that uses sensors and cameras to track the user's position and overlay holographic images onto the real-world environment. It can be argued that this is the most advanced technology available on the AR market for HMD.

AR solutions cover a wide spectrum of existing and nascent use cases and have applications across various industries, such as manufacturing, healthcare, and education. In the manufacturing industry, AR solutions can be used to provide workers with real-time instructions and guidance, reducing the risk of errors and improving efficiency. In the healthcare industry, AR solutions can be used to provide medical professionals with visualizations of patient data, improving both diagnosis and treatment. In the education industry, AR solutions can be used to provide students with more interactive digital learning experiences, improving both engagement and retention.

Real World Use Cases For Augmented Reality

One of the companies to have implemented AR solutions in the manufacturing industry is Bosch. Bosch's AR solution provides workers with real-time instructions and guidance using HMDs or mobile devices. The solution enables workers to access relevant information (thinkwork instructions and safety guidelines) without needing to stop working or consult a manual. The AR technology allows for faster and more accurate diagnosis and repairs, which in turn can increase workshop efficiency and reduce vehicle downtime in the shop. By displaying the necessary repair instructions and diagnostic data in real-time and in the mechanic's field of vision, the company can also reap the benefits of  reduced errors and improved safety.

Another example can be found with the Philips IntelliSite Pathology Solution. Their approach utilizes AR to improve the efficiency and accuracy of diagnosing diseases such as cancer. The program uses high-resolution digital pathology scanners to create digital images of biopsy samples. These images are then uploaded to the cloud where pathologists can access them from anywhere in the world using AR-enabled devices such as smartphones, tablets, or smart glasses. The AR technology overlays the images with markers and annotations to highlight areas of interest and help pathologists identify abnormalities.The solution allows pathologists to view digital images of biopsy samples in real-time enabling pathologists to make faster and more accurate diagnoses, ultimately improving patient outcomes. 

In the education industry, Google is one of the companies developing and implementing AR solutions. Google's ARCore provides developers with tools to create AR experiences for Android devices. ARCore can be used in various educational applications, such as virtual field trips and interactive learning modules.

AR solutions can also be leveraged in the retail industry to provide customers with an interactive shopping experience. An active example can be found with Snap Inc, the parent company of Snapchat. They announced a partnership with the luxury jewelry company Tiffany & Co. with their collaboration centered around a new augmented reality (AR) experience that allows Snapchat users to virtually try on and purchase Tiffany's products.

The AR experience, called "Tiffany Try-On," utilizes Snapchat's camera and AR technology to overlay 3D models of Tiffany's jewelry onto the user's body, allowing them to see how the pieces would look before making a purchase. Referring back to the beginning of this article, this solution is mobile and marker-less. The partnership with Tiffany is part of Snap's ongoing efforts to integrate AR technology into e-commerce. The company has previously partnered with other brands, such as Nike and Gucci, to create AR try-on experiences for their products.

Overall, the partnership between Snap Inc and Tiffany & Co. represents a significant step forward in the integration of AR technology into the retail industry, particularly for luxury brands. By allowing customers to virtually try on products before making a purchase, AR technology has the potential to increase customer engagement and drive sales for e-commerce retailers.

Augmented reality solutions have already shown their potential to revolutionize many industries, and the future for this space is bright. With the continued development of mobile devices and wearable technology, AR solutions will become more accessible and intuitive, leading to even more widespread adoption. As AR technology becomes more sophisticated, it will become possible to create even more realistic and immersive experiences. Additionally, the integration of AR technology into e-commerce will likely continue to grow, as companies look for new ways to engage customers and increase sales. Overall, the future of augmented reality solutions looks promising, and we should expect to see even more innovative applications and use cases in the coming years.
