　　The weather system of Racing Plan sets the weather conditions in the course of the competition in a complicated way. Generally speaking, it can be divided into as many as 14 kinds of weather, such as sunny, cloudy, foggy, cloudy, rainy and stormy, and players can set different weather conditions for different stages of the whole competition. Perhaps the last stage of the competition is still foggy, and the next stage is clear Wan Li, or thunderstorms. Players should never think that the so-called weather system is just a decoration, which is dispensable-in fact, in thunderstorm, storm and rain, the number of game frames will be only half of that in sunny days, while in foggy days, the number of game frames will be increased.

　　

　　Wandering stars

　　

　　On sunny days, the number of game frames is 89.

　　

　　Wandering stars

　　

　　The number of game frames in rainy days is 45, which is only half of that in sunny days.

　　

　　If a player thinks that his configuration can race smoothly in sunny days and he is careless about competing with others, perhaps the frame will be greatly dropped because of the sudden change of weather, and the game will become extremely stuck, thus losing the chance of winning the game. If you want to firmly grasp the victory in your hands, and see how Xiaobian can help you.

　　Ultrasonic fingerprint recognition is widely used in high-end smartphones, tablets, and devices requiring high security levels, making it suitable for users prioritizing security and precise recognition.

　　

　　Optical Fingerprint Recognition

　　

　　Working Principle

　　

　　Optical fingerprint recognition technology uses light to illuminate the fingerprint surface and captures an image of the fingerprint through a camera. When a user places their finger on the sensor, the sensor shines a light on the finger to obtain an optical image of the fingerprint. The system analyzes the feature points in the image to recognize and match the fingerprint.

　　

　　Advantages

　　

　　1.Lower Cost: Optical fingerprint sensors are relatively inexpensive, with mature manufacturing processes, making them widely used in mid-range and budget smartphones.

　　

　　2.Simplicity and Usability: Optical recognition technology is familiar to users and easy to operate, providing a relatively good user experience.

　　

　　Disadvantages

　　

　　1.Environmentally Sensitive: Optical sensors are highly sensitive to oils, dirt, and dryness on the fingerprint surface, which may lead to recognition failures and affect usability.

　　

　　2.Lower Security: Optical recognition primarily relies on surface images, making it susceptible to spoofing by fake fingerprints made from materials like gel or glue, posing security risks.

　　

　　Application Scenarios

　　

　　Optical fingerprint recognition is widely used in mid-range smartphones, portable devices, and scenarios where security requirements are relatively lower, making it suitable for everyday consumer use.

　　

　　Future Development Trends

　　

　　As technology continues to advance, fingerprint recognition is also evolving. In the future, ultrasonic fingerprint recognition may become more prevalent, with costs expected to decrease, allowing it to enter more mid-range devices. At the same time, optical fingerprint recognition is continuously improving, potentially incorporating more security measures, such as enhanced live detection and multimodal biometrics (combining with facial recognition, etc.).

　　

　　Moreover, with the development of artificial intelligence and machine learning technologies, the accuracy and efficiency of fingerprint recognition may further improve, providing users with a safer and more convenient experience.

　　

　　Conclusion

　　

　　Both ultrasonic and optical fingerprint recognition have unique advantages and disadvantages. Users should weigh their needs, budgets, and application scenarios when making a choice. If you prioritize higher security and accuracy, ultrasonic fingerprint recognition may be the better option; however, if you are more concerned about cost and everyday usability, optical fingerprint recognition is a reasonable choice. Understanding the differences between these two technologies can help you make a more informed decision when purchasing a smartphone.
