What is digital human
Digital human is a visual digital virtual human integrating many world leading artificial intelligence technologies such as character image simulation, character voice cloning, natural language processing, knowledge graph analysis, etc. He can have accurate interactive dialogue with real people anytime and anywhere by copying and simulating characters, cloning characters’ voices and speech synthesis.
What are the application scenarios of digital humans?
1. Virtual Brand IP
Enterprise virtual brand IP is a kind of commercial application of virtual digital human. The desire for virtual people is more about transforming the simple shopping relationship between brands and consumers into a social relationship. But most brands still face the need to figure out the more immediate and effective value of virtual people to the enterprise. Although the current enterprise has the consciousness of IP construction, but generally do not have the ability of IP construction. Compared with the mature brand system overseas, the brand building level of Chinese enterprises is still in the early stage. And brand IP is a systems engineering. To make virtual human personality, it requires not only the investment of face, but also the pursuit of more perfect technical level, interactive experience, and professional knowledge structure. So, it takes a lot of artificial intelligence behind a virtual human to sustain it.
Traditional enterprises should be the place where digital human produce the greatest application value in the future. After all, only when they go deep into the enterprise application can they realize the massive transformation of value. Although many enterprises have realized their own digital human at present, but most of them are still in the way of virtual IP, the real implementation of the enterprise’s specific application is very few, the most difficult is still to find the right application scenario. We think enterprise digital human customer service should be one of the most valuable scenarios for digital human implementation in the enterprise. Using “live, smart” digital human to answer users’ questions will bring customers a friendlier and more interesting experience than AI hotlines. However, this not only has high requirements for the image of digital human, but also has higher requirements for customer service AI.
Games are the home of digital human. After all, the source of digital Man technology comes from games (Unity and Unreal game engines are the main drivers for digital Man). As it matures in games, it spills over into other industries and application scenarios. Much of the production of images and animations, as well as the rendering of images, was developed because of games. Of course, a lot of digital human technology companies are also a lot of game development enterprises. Of all kinds of games, RPG games in particular (the role-playing genre) are the most similar to the current digital man. Role-playing games are also the largest market in terms of revenue. AR and VR games based on 3D virtual devices are pushing the game-based applications of digital human to a broader position.
Advantages of Digital Human
1. Authenticity: The most important value of virtual people is to provide users with a more real way to interact. Through the deep integration of AI technologies such as computer vision, speech recognition and natural language processing, it fully simulates the real and sensible dialogue and interaction between people to achieve the effect of “understanding, seeing and speaking”.
2. High efficiency: From the perspective of interactive efficiency, with the help of screen carriers such as large screens of mobile phones, virtual digital human can not only present multimedia information that voice and text robots cannot display, such as charts and texts, so that information transmission is more abundant and accurate; Output online and offline interaction or operation content with high frequency; Efficient integration of identity recognition, gesture recognition, emotion recognition and other interactive tasks.
3. Sensibility: The visualized real image gives digital human unique emotional attributes, and the service temperature and visual emotional benefits brought by the real image help to establish a humanistic emotional bond. Especially for the elderly alone, left-behind children and other groups in need of companionship; Or a virtual idol or virtual IP that can build emotional bonds.
Challenges of Digital Human
1. Modeling: Long Production Cycle
At present, the efficiency of digital human production is still relatively low. If the current mainstream process is followed, every digital human is manufactured by manual modeling or by scanning reconstruction, the production cycle is long and the cost is difficult to reduce. The construction of an open platform that supports high degree of freedom virtual human image tools and gathers a large number of digital model assets will become an essential link to lower the production threshold and reduce the initial investment.
On the open platform, users can quickly generate customized digital human images through the face-pinch system, body shape system, makeup system, material system and other systems. The infinite expansion of digital model assets can also realize the creation of character models, clothes and scenes at low cost, so as to improve the production efficiency of digital human, reduce the production cost, and promote the digital human for multiple application scenarios to become a popular service.
2. Drive: High Technical Cost
The commonly used motion capture schemes are divided into optical and inertia. With the further development of technology, the motion capture technology will be iterated towards a more intelligent and convenient direction. The continuous upgrade of software algorithm can realize AI-based visual motion capture, which does not rely on high-cost equipment. Real-time expression and full-body motion capture can be realized only by relying on monocular camera. More intelligent algorithms and algorithms with advanced repair and simulation capabilities will greatly reduce the difficulty of digital human-driven technology and become one of the core competitiveness of digital human enterprises.
Rendering: Great Challenge to Terminal
Digital human from 2D to 3D to hyper-real, picture quality from 1080P to 4K to 8K, highly realistic ultra-high quality performance of virtual humans have brought geometric growth in rendering, and the demand for real-time interaction requires terminal devices to complete huge calculations within millisecond response time, which undoubtedly brings great challenges to user terminal performance.
Therefore, putting the entire virtual human rendering process on the cloud and letting the terminal device only serve as a display device is an effective solution to lower the threshold for the popularization of digital humans. With the separation of computing and display, whether it is a super-realistic digital human with fine texture hair or 8K, 16K high-quality digital human, it can be applied to mobile phones, lightweight VR, and low-computing display screens, promoting the application of digital human Full landing.
