With the continuous advancement of technologies such as AI intelligence, autonomous navigation, and transparent screen display, as well as users’ expectations for “anthropomorphic” and “immersive” interactive experiences, a new type of interactive terminal, the “mobile AI digital human,” is accelerating towards large-scale commercial application.

In various exhibition halls and pavilions, retail guidance, teaching and government affairs, and even in home scenarios, mobile AI digital humans build a more authentic and warm human-machine relationship through “active service + vivid interaction,” and have become an important tool for improving service efficiency and user experience.

A multi-media solution provider has joined hands with Touchfly, hoping to create a mobile AI digital human interactive screen applied to digital exhibition halls, which can replace manual labor to realize functions such as content presentation, venue guiding, and voice interaction.

This device not only needs to run AI algorithms to drive the simulation and display of digital humans, but also needs to achieve functions such as automatic obstacle avoidance, path planning, and user perception through the collection of data from sensors such as radar, depth cameras, cameras, and microphones. Therefore, strict requirements are put forward for the performance of the core control motherboard:

• The operation of AI algorithms requires a high-performance CPU and NPU acceleration.
• A refresh rate of 4K/60Hz or above is required to ensure that there is no delay in the picture.
• It supports CAN/RS485 bus communication, as well as multi-expansion capabilities of PCIe and USB.
• It can adapt to complex environments such as high and low temperatures, vibrations, and electromagnetic interference.

After meticulous model selection, the customer has chosen the Touchfly CX-3588 motherboard as the control core of the mobile AI digital human. With its powerful computing power architecture and industrial-grade design, it helps the customer create a smarter, more reliable, and more flexible AI digital human terminal.

Surging computing power, full-scenario AI acceleration

The Touchfly CX – 3588 is equipped with the Rockchip® RK3588 high – performance processor. It features an octa – core architecture of 4×A76 + 4×A55, with a main frequency of up to 2.4 GHz. Meanwhile, it has a 6 TOPS NPU and a Mali-G610 GPU working in tandem, along with a maximum of 32GB high-speed RAM. It can easily handle complex tasks such as SLAM navigation, AI inference, visual processing, and 4K digital human dynamic rendering, ensuring smooth interaction responses for digital humans.

Abundant Expansion, Flexible Function Adaptation

The CX-3588 is equipped with a variety of independent display interfaces, including LVDS, eDP, HDMI2.1, and MIPI. The HDMI supports video output up to 8K/60Hz, and the Mipi Camera supports the data transmission of a 13-megapixel high-definition camera, which can quickly capture users’ images and achieve a more precise interactive experience.

At the same time, the CX-3588 motherboard is equipped with a rich set of I/O interface functions, including 2 Gigabit Ethernet ports, 6 USB ports, 5 serial ports (RS232/RS485/TTL), 1 CAN port, and 6 GPIO input/output ports, supporting the access of sensor clusters such as cameras, microphones, and motor drivers. It has built-in mini PCIe and M.2 interfaces for expanding 4G/5G or WiFi6/bluetooth modules, ensuring data synchronization and cloud-based collaboration, and enhancing the intelligence level of AI digital humans.

Industrial Protection, Ensuring Safe and Reliable Application

The CX-3588 can operate in a wide temperature range from -20°C to 70°C and a wide voltage range of DC 12V-36V. It has passed reliability tests such as vibration resistance, interference resistance, and anti-static (±8Kv~±15Kv) tests. A three-proof coating is added to the surface of the PCB for protection, enabling it to stably cope with various complex industrial scenarios.

With the rapid development of large AI models such as Deepseek, ChatGPT, it has become a trend for mobile AI digital humans to access generative large language models, which will further enhance the natural language interaction and expression capabilities of digital humans.

In response to this change, Touchfly has actively deployed the industrial + AI application model. With a high-performance computing power platform, excellent hardware performance, and energy efficiency, it can help customers implement intelligent applications at a relatively low cost and enhance their market competitiveness.
