The unused UI is just a legend that the key is to be easy to use.

"Don't think that there are many Internet products, you must design a clear UI to win the game. A lot of interaction methods and operation methods are taken for granted now, but we have already passed the 'learn' level more than a decade ago. Take a look at Apple's previous * mouse teaching video as follows) * You will understand. You may not have watched this video, but you may not be born with a mouse. It must have passed the process of imitating others or exploring yourself ."

So what you need to worry about is not how your product can be used at first glance.Make the learning process simple enoughUsers can easily learn how to interact with products.

I suddenly thought of a very popular "zoom gesture" pinch-to-zoom ). In the past, I never wanted to slide my finger on the screen of my cell phone and try to enlarge the picture, not to think about the pictures in the newspaper. In the old impression, the pictures in the mobile phone are fixed in size. But now, we use a scaling gesture to naturally look like a natural skill. It may be because this action is in line with people's operational behaviors. It is easy to learn, easy to remember, and naturally smooth.

I personally think that "Shake" is also a model of interaction. Before that, you never thought about what to do with your cell phone. But it is just a few factors, such as "simple guidance", "fun", and "Easy to remember" that you will not forget it after trying it. Therefore, the UI is not intuitive,The user's learning cost is low enough, the learning process is interesting enough, and the learning result is satisfied enough..

I also want to add that it is best to add "feedback" to guide users in learning, such as voice feedback during phone calls and vibration feedback when they touch the mobile phone keyboard. Only by giving feedback to the user can he know whether his exploration is in the correct direction.
