And the "400 ms response time" node value is named "Doherty Threshold" after WJ Doherty. Although we have long taken it for granted that the system has executive email list a fast response time, the proposal of the "Doherty threshold" was pioneering at that time. Because around the 1970s, the computer research community generally used "the response time of the executive email list system can be 2000 milliseconds (2 seconds)" as the industry standard. Although I can no longer query the scientific research literature of this "2 seconds" old knowledge, but in the PPT of a
European online lecture held by IBM in 2018, we can also see: Therefore, the "Doherty Threshold" can be said to be an indicator that redefines the response executive email list experience in the field of modern human-computer interaction, affecting the visual side, interaction side, experience side, and development side of a standard product. Second, the use of the Doherty threshold We need to be clear that the "Doherty Threshold" is a maximum reference value executive email list for system response time given by IBM. It does not mean that the response time of all machines must be stuck at the node of 400 milliseconds, but the response time. It should be kept within 400ms, try not to exceed 400ms.
So knowing the range value of "within 400 milliseconds", as designers, how do we apply it to our design work, or what design standards will the "Doherty executive email list threshold" affect us? - Take a look at the system action specification of Google's Material Design, which should give you some direction. Point 1: Faster is not always better As designers executive email list and developers, we all hope that the system can respond to user operations as quickly as possible. But it's not necessarily a good thing to blindly pursue speed. Material Design emphasizes the concept of "transition time"
