EchoMind Blog - What is a digital human

What is a digital human, what is its future outlook?

In today's technologically advanced world, lifelike digital humans have become an emerging field of great interest. As a digital virtual image that is close to the human form, created based on computer graphics (CG) technology and artificial intelligence technology, digital humans can provide people with more convenient, efficient, and personalized services. At the same time, the emergence of digital humans can also promote the development of the virtual economy, providing more opportunities for digital content innovation and digital consumption.

What are digital humans?

Digital humans are digitized human figures created using digital technology that closely resemble human images. From a narrow perspective, digital humans are the product of the integration of information science and life science, using the methods of information science to virtually simulate the form and function of the human body at different levels. From a broad perspective, digital humans refer to the penetration of digital technology at various levels and stages of human anatomy, physics, physiology, and intelligence.

The core technologies of digital humans include computer graphics, motion capture, image rendering, and artificial intelligence.

Computer graphics can simulate the appearance, posture, and expressions of humans, giving digital humans realistic visual effects.

Motion capture technology converts the movements and expressions of real people into digital signals, which can drive the movements and expressions of digital human models, making them similar to or more expressive than real people.

Image rendering is used to reproduce the visual effects of the real world in a digital environment, which requires precise calculations for lighting, color, material, etc., to create lifelike images.

Artificial intelligence gives digital humans a "soul," enabling them to have intelligent interactive capabilities, which is also the key technology for users to feel more personalized digital humans.

What types of digital humans are there?

With the continuous iteration of technology, the production efficiency and intelligence level of digital humans are also continuously improving, and their application scope is constantly expanding. According to the classification of business scenarios, there are mainly four types:

First, virtual agents

Virtual agents, through natural language processing and machine learning technologies, can provide automated and intelligent information consultation and services for enterprises and customers. Virtual agents are commonly used in various fields, such as customer service, education and training, financial consulting, etc.

Digital humans can serve as a form of virtual agents, especially in the field of customer service. Through digital technology, digital humans can provide uninterrupted customer service 24 hours a day and can understand and answer customer questions through natural language processing technology. In addition, digital humans can also provide more personalized services by analyzing customer data and feedback.

Second, virtual assistants

Virtual assistants are an advanced form of chatbots that handle more complex interactions in a conversational manner. The main function of value-added services is to use advanced artificial intelligence, natural language processing, and machine learning to recognize voice commands. Service providers can use other platforms, for example, to access users' calendars and emails to schedule meetings, send emails, buy concert tickets, or book hotels.

Additionally, the use of digital assistants has great potential in industries such as healthcare and retail. For medical professionals, digital assistants can help improve training and procedures. Doctors can perform surgery in a realistic simulated environment, where they can undergo hundreds of simulations to ensure the best results before performing surgery in real life. In the retail industry, AI digital assistants can enhance customer service by providing a more personalized experience.

To achieve this, digital assistants need to have a good understanding of language communication. This is key to helping people interact and converse better with digital assistants so that they can complete the tasks they need.

Third, virtual idols

Virtual idols are an application of digital humans that are usually active on social media networks and have influence and dissemination power. Virtual idols can be fictional virtual characters or digital representations of real people. Compared to ordinary digital humans, virtual idols pay more attention to image and performance and usually require professional planning and production teams to create.

Fourth, virtual customer service

Virtual customer service is also created through digital technology, but it is mainly used in the field of customer service. Virtual customer service is usually deployed on corporate official websites, online customer service systems, intelligent customer service, and other platforms to interact with users in real-time through text, voice, video, etc., to assist users in solving problems and obtaining information.

Fifth, virtual companions

Virtual companions provide emotional support and establish personal relationships with users. Researchers believe that this developing technology has had the greatest impact on elderly care by reducing loneliness and helping people stay at home longer. In addition to reminding people when to take medication or see a doctor, virtual companions will also be able to converse and show empathy.

However, it should be noted that the development of digital humans also faces some challenges. First, the creation of digital humans requires high costs and technical support, and only a few professional companies can invest a large amount of money and technology in research and development. Second, the behavior and performance of digital humans still have limitations and deficiencies, such as the lack of real human emotions and consciousness, and the inability to fully simulate the behavior and language of real humans. In addition, the popularity and acceptance of digital humans also need to be further improved. Although digital humans have made certain progress, more technological advances and practical applications are needed to make them more natural, real, and useful.

Therefore, in order to make digital humans more lifelike, further technological innovation and research are needed to continuously improve their intelligence level and behavioral performance.

In conclusion:

In summary, as an emerging field, digital humans are full of opportunities and face challenges. But it is certain that with continuous technological innovation, digital humans will continue to mature and become an indispensable part of people's lives and work.
