Understanding and thinking about the concept of flat design

Now the concept of flat design has been deeply rooted in the hearts of the people, but what is flat design? I am afraid that the benevolent sees benevolence, and the wise sees wisdom. Everyone has different opinions, because different positions have different understandings of flat design, but the real flat design is mainly analyzed based on the following three dimensions:
first, simplicity and efficiency. The design of the mobile terminal is based on micro-tasks. Micro-tasks are tasks that need to be solved and completed quickly, so users have a short time and high efficiency when using them, so that the user experience will be very good. If the user cannot complete the task in a short period of time, the user will immediately lose patience and go to another product to solve the problem. Therefore, a flat design must have a simple interface layout and efficient user operation.
Second, the optimization of the level. This is explained from the level of interaction. According to the flattening concept of Windows iphone, it is best to use the interaction concept of Metro UI to design products, which is to put the functions and controls that users need as much as possible in one On the plane, it does not require too many layers for users to search. If users are constantly searching, users will lose patience, and this kind of experience is also very bad. Therefore, we must avoid dividing into many levels, and try to let users quickly find the functions they want to operate in one plane.
Third, openness and compatibility. The mobile Internet is an open platform. Therefore, we try our best to think with an open and inclusive mentality when designing. What we need to do is a small and beautiful product with micro-tasks, so that this product can be quickly Products embedded in other platforms need to be compatible with different platforms and different devices, and the design of mobile Internet products must be considered in a relatively large pattern.
The above three aspects of interpretation are just to show the connotation and essence of flattening from three different dimensions. Specifically, with the continuous development and improvement of the Internet product design concept, the meaning of flattening will become more and more abundant.
