In the Android Design website, not only the specific elements of application design are described, but also the basic principles of Android whatsapp database application design are specified. There are 17 of these principles in three categories: Enchant, Simplify, Surprise (Enchant, Simplify, and Amaze). What are the considerations behind these principles? At this year's I/O conference, two designers talked about the psychology of Android's design principles. This is reported on the Co.Design website. Based on extensive whatsapp database user research, the two designers collaborated to write the design principles. They say that emotion is an important reference factor for the Android team when it comes to UX design. The design team followed the idea of ​​psychologist Barbara L. Fredrickson: To fight one negative emotion, you need three positive emotions.

Taking this as a reference, when considering a problem, the design team will judge the pros and cons of a solution based on the design principles. They used the analogy of two jars, one for positive emotions and the other for whatsapp database negative emotions. A good plan fills the jar of positive emotions and empties the jar of negative emotions. For example, when designing the Android home screen, how to let users know that they have reached the last screen? The design team can choose to do nothing. Doing so would undermine two design principles and create two negative emotions. Another option whatsapp database is to pop up a line of text on the screen telling the user that the last screen has been reached, but this would still violate The "it's not my fault" principle, as the pop-up notification is like telling the user that something is wrong, and also violates another principle, "only bother me when it matters".

The final solution of the design team is that when the user reaches the last screen, if they continue to flip, the screen will tilt to whatsapp database the side and change color. With animations like this, the user realizes that they have reached the last screen. This follows four design principles that add four positive emotions, including surprising people in a special way, sporadic encouragement, using pictures instead of words, and tricks that can be used elsewhere. It is conceivable that in the specific design process, it is impossible for the whatsapp database design team to rigidly apply the principles. However, through this example, we can see that the Android design team attaches great importance to user emotions. Today, mobile products have penetrated into our lives, and the tiny design details in the products can often affect our mood.
