The COVID-19 pandemic has accelerated the adoption of digital technologies at a faster speed than we could have imagined. As business undergoes change, companies are realizing the power of technology to unify dispersed, global talent. Virtual learning and telehealth are also becoming more advanced and could deliver benefits throughout the world.

Because new technologies are developing so quickly, it's difficult to predict exactly what the future internet will look like, but there's no doubt that the latest iteration of the web will transform nearly every part of our economy and society. 

As organizations look to take advantage of virtual worlds and the opportunities they present, they can explore these virtual worlds inside the studio, in the real world, and in the context of their businesses, providing a range of benefits that include: 

• Working alongside the designers and architects of virtual worlds, learning the new generation of creative tools, and simulation technologies that enable Unlimited Realities. 

• Creating hyper-realistic, physically-accurate digital twins that simulate natural environments, physical structures, industrial operations, transportation networks, including the humans and robots and AI agents working inside them, to accelerate design and planning cycles for all business paradigms. 

• Building shared virtual experiences that convene audiences for collaborative work, recreation, or education through AR/VR or mixed reality. 

• Exploring virtual world economies where transactions in digital currencies and assets will power an explosion of virtual services, experiences, and goods. 

• Enabling virtual world strategies that maximize positive impact on the planet, advancing client’s environment, social and corporate governance initiatives.

- Digital Content and Technologies

Our world has countless images and videos from the built-in cameras of our mobile devices alone. But while images can include photos and videos, it can also mean data from thermal or infrared sensors and other sources. Along with a tremendous amount of visual data (more than 3 billion images are shared online every day), the computing power required to analyze the data is now accessible and more affordable. 

This is a trivial problem for a human, even young children. We require at least the same capabilities from computers in order to unlock our images and videos.  

• A person can describe the content of a photograph they have seen once.
• A person can summarize a video that they have only seen once.
• A person can recognize a face that they have only seen once before. 

Sharing engaging and immersive visual content such as photos, videos, 360-degree and real-time augmented experiences is at the heart of staying connected and building community. 

Developing and refining advanced real-time computational photography and image understanding techniques that allow us to enhance our images and video, track and enhance faces, bodies and the 3D world, and capture and share the 3D world with high fidelity.

Research scientists and engineers span a myriad of disciplines including computer vision, computer graphics, computational photography, machine learning, interaction technologies and mobile development to unlock the commercial potential of virtual worlds.

- Computer Vision Technology

For many decades, people dreamed of creating machines with the characteristics of human intelligence, those that can think and act like humans. One of the most fascinating ideas was to give computers the ability to “see” and interpret the world around them. The fiction of yesterday has become the fact of today. 

Thanks to advancements in AI and computational power, computer vision (CV) technology has taken a huge leap toward integration in our daily lives.

CV is the field of computer science that focuses on creating digital systems that can process, analyze, and make sense of visual data (images or videos) in the same way that humans do. 

The concept of CV is based on teaching computers to process an image at a pixel level and understand it. Technically, machines attempt to retrieve visual information, handle it, and interpret results through special software algorithms. 

CV is an AI field that uses deep learning models and digital images to help machines understand and interpret the visual world. 

CV uses common tasks such as: 

• Image classification
• Object detection and localization
• Image segmentation

CV has many applications, including:

• Healthcare: CV can help automate tasks such as detecting cancerous moles in skin images or finding symptoms in x-ray and MRI scans. It can also detect neurological and musculoskeletal illnesses such as approaching strokes, balance issues, and gait issues.
• Manufacturing: CV can monitor manufacturing machinery for maintenance purposes and can also be used to monitor product quality and packaging on a production line.
• Self-driving cars: CV can help self-driving cars.
