Digital twin technology has the power to revolutionize how individuals, manufacturers, and systems generate and test new products and ideas. Even as scholars and industries work on creating one cohesive definition of what a digital twin is and what it can do, the concept is revolutionizing how organizations can test products and understand how their equipment, facilities, or their business’s organizational structures work. With such understanding, organizations can create increasingly optimized processes and products.
With use cases ranging from product prototypes to talking-head video generation, the possibilities are vast. We’ll define what a digital twin is and explore the many types and benefits of this technology.
What is a Digital Twin?
A digital twin is a digital representation of objects, people, or processes, whether real or intended. Digital twins utilize real-time data, simulation, machine learning, and reasoning to simulate real situations, demonstrating possible outcomes so organizations can make better decisions.
Digital twins transform industries and businesses by providing a holistic understanding of objects or systems quickly and effectively, optimizing decision-making, processes, and more. They utilize both historical and real-time data to represent their models in the past, present, and (predicted) future, allowing for more effective predictive capabilities and streamlined planning processes.
Digital twin models are often broken down into two categories:
- Representational models that use data (historical and live) to represent entities and processes
- Computational simulation models, which are executable models of processes consisting of data and algorithms to create virtual representations.
Digital twin models can take the form of mathematical equations, databases, spreadsheets, or 3D models.
How Does Digital Twin Technology Work?
Digital twin technology uses data gathered from sensors placed on real-world objects or assets to replicate those assets in a digital environment. A digital twin utilizes technologies like AI and the Internet of Things to gather and transmit data and to create the digital model of the asset.
With digital twins of products, businesses can study the lifecycle of an asset; with that data, organizations can understand their strengths and weaknesses from product testing all the way to real-world performance. With digital twins of humans, like those Tavus creates, users can replicate their image and movements to automate video generation, allowing for personalization and saving the time, effort, and money required to record in real life.
Who Invented Digital Twins?
Dr. Michael Grieves first applied the concept of digital twin technology to manufacturing and formally announced the concept of digital twin software in 2002. The original concept was proposed by David Gelernter in his 1991 book Mirror Worlds. However, the central idea of a digital twin as a means of studying objects appeared decades prior. During NASA’s space exploration missions in the 1960s, the agency pioneered the concept of digital twin technology when they used exact replications of each spacecraft for earth-bound study and simulation.
In 2010, NASA’s John Vickers introduced the term “digital twin” in relation to Grieves’ technology.
Benefits of Digital Twins
The benefits digital twins provide differ depending on what industry uses them and the purpose of each use case. We’ll explore some of the top benefits of using digital twins.
Expedited testing & development
Digital twins provide companies with the ability to test digital replicas of potential products before those products even exist in reality. Whether they’re building products or facilities, organizations can use the digital replica to observe failures or weaknesses and address them before moving into production.
Without the time-consuming need to build models for initial testing and to create new models based on observed weaknesses, testing and development processes accelerate. As a result, products get to the market faster and organizations have more time freed up for greater innovation.
Improved performance & reduced downtime
The real-time insights provided by digital twin testing allow organizations to optimize the performance of facilities, equipment, and more without delays. If problems are solved as they happen, systems reach optimal performance and reduce the once-inevitable delays of regular maintenance.
Greater sustainability
Manufacturers often use digital twins to improve not only their production processes but their sustainability, as well.
Several manufacturers have discovered this benefit inadvertently, discovering their increased sustainability after utilizing digital twin technology for other primary benefits. LG Electronics, for example, discovered that incorporating digital twin technology in their Changwon, Korea, factory not only improved productivity by 17% and product quality by 70% but also reduced the factory’s energy consumption by 30%.
The ability to observe products and systems both before going live and in real time (post-production) allows organizations to identify areas of inefficiency and waste. This real-time observation helps organizations prevent waste before it happens.
Types of Digital Twins
Digital twins come in various forms; let’s explore some of the most common types of digital twins.
People
Human digital twins come in different forms and are used for varying functions. One such possibility is the ability for individuals to create their own personal digital twin through AI face generators like Tavus. With just a short video of you speaking, Tavus AI can create a replica of your face, matching your face, voice, expressions, and movements. People-type digital twins support personalized marketing, onboarding, and more at scale while also helping organizations avoid the often labor-intensive work of video recording with real-life humans.
Another application of people-type digital twins is the use of AI technology to replicate the personalities and characteristics of real people and use those replicas to predict and observe human behavior and interactions. Even healthcare is using digital twins to revitalize the industry through the development of “smart” healthcare. By creating human replicas, digital twin technology may allow for improved health management through the technology’s predictive capabilities.
Product or Prototype
Digital twin technology allows for the creation of virtual products or prototype replicas. These digital replicas help manufacturers explore how a potential product works and determine strengths and weaknesses before the product is even created. Prototype digital twins streamline the process of manufacturing, from product development to end-user interaction.
Processes
Process twins provide a digital representation of the components and workings (or processes) of a physical or digital object. The digital process twin can reproduce how facilities or objects operate and determine how to create optimized functioning. These replicas provide comprehensive looks at new and existing products through the continuous collecting and organizing of data from sources like suppliers, raw materials, and final products. Process twins help monitor process variables, manufacturing time, and more.
Systems
Systems twins use digital twin technology to examine how assets work together. Organizations use these twins to explore how well their systems work and what enhancements they can make to improve performance.
One large-scale example of systems twins is the Earth System Digital Twins (ESDT) efforts of NASA. The agency uses digital twin technology to develop models for diverse Earth and human activity to allow for continuous observation and data, allowing for more comprehensive representations and predictions. These models are aimed to support decision-making about how to support Earth systems and to provide actionable information for current and future endeavors.

Learn More About Digital Twins
Let’s learn a little more about what, exactly, digital twins are and answer some frequently asked questions.
Digital twins vs simulations
Digital twins and simulations are similar in that they are both virtual simulations based on models. Simulations, however, are usually used for design or offline optimization, where designers input changes to the simulations to observe possible scenarios. Digital twins instead create larger-scale, complex virtual environments and provide wider application possibilities.
Real-time integration is another key feature of digital twins as opposed to simulations; while digital twin technology allows for real-time data to update the virtual model, simulations can only use predefined data sets. Alongside the real-time data, users can interact with the digital twin model, whereas simulations only allow interaction before the simulation occurs (through the setting of variables).
With a lack of real-time data and changes, simulations’ utility is often limited to specific scenarios. Digital twins instead maintain continuous relationships with their physical counterparts, allowing continual monitoring and analysis.
Although simulations are often used for predictive analysis, their lack of real-time data integration prevents continual updates in analysis. Digital twins can help organizations make quick and efficient decisions whenever the model shows changes.
Are digital twins AI?
Digital twins, which were fully realized in 2002, haven’t always used AI technology. However, the growing integration of digital twins and artificial intelligence has revolutionized the possibilities of this technology.
AI gives digital twin technology more sophisticated predictive abilities and more intelligent automation, making digital twin technology a more proactive tool due to its new ability to learn from real-world assets continually. Thanks to AI, these improved capabilities allow for increased optimization based on digital twin models and analyses.
AI has also streamlined the experience of working with digital twins, since AI can understand voice commands and gestures and anticipate your next move. Architects and engineers, for example, can control their building or engine models with gestures or voice commands, creating a more seamless interactive process.
Is digital twin the same as virtual reality?
Digital twin and virtual reality (VR) technology are actually two distinct technologies. Digital twin technology replicates objects, people, processes, or systems in the digital space, providing a model for users to observe and from which they gain valuable analysis and insight.
Virtual reality is instead a completely immersive simulated environment, in which the user feels as if they are actually existing in and moving through a simulated world. VR also requires a specialized headset or other hardware to allow users entry into the simulation. Once they “enter” the simulation, they can interact with objects rather than simply observing.
Some industries, however, have seen the potential of combining digital twin and VR technologies. Digital twin technology would provide the real-time models and capabilities for analysis and continuous monitoring, while VR can provide an immersive experience of the model to help stakeholders fully understand the data and simulations.
What is digital twin software?
Digital twin software is a computer program that allows users to create digital twin simulations based on their data and their organization’s predictive or analytical needs.
Software is the set of programs, data, or instructions that instruct a computer what to do and how to do it. In the case of digital twin software, the programs, data, and instructions allow developers to create their virtual models using the predefined program controls. This allows them to use digital twin technology without needing to understand the hardware that makes it possible.
