# 2. Graphical Display Requirements in Autonomous Driving Systems

With the rapid development of autonomous driving technology, graphical display plays an important role in autonomous driving systems. In this chapter, we will discuss the graphical display requirements in autonomous driving systems, including real-time requirements, presentation of driver information, and interface friendliness and operability.

### Real-time Requirements

In autonomous driving systems, graphical display must have very high real-time performance to ensure that drivers can obtain key information such as vehicle status and road conditions in a timely manner. This requires the display to respond quickly to the data transmitted by the system and to update the displayed content in a timely manner to keep in sync with the actual driving scenario.

### Presentation of Driver Information

To ensure that drivers can accurately understand the information conveyed by the system, graphical display needs to be clear and straightforward. Drivers may need to see various information such as the current speed of the vehicle, navigation information, and the status of surrounding vehicles. Therefore, graphical display needs to have sufficient resolution and color depth to present all types of information clearly.

### Interface Friendliness and Operability

The graphical interface of an autonomous driving system needs to have good friendliness and operability to allow drivers to easily obtain the required information and perform operations. The interface design should be simple and clear, and interactive operations should be intuitive and convenient, avoiding overly complex and cumbersome operation processes, thereby enhancing the driving experience and safety of the drivers.
