We encounter and process vast amounts of information every day. Consider all the information you come across today - how much of it is actually relevant and useful to you. Most of the information we encounter is noise —that is, irrelevant to our current needs. Rather, information that is relevant and useful to us—that is, information that we are looking for special database or want. Signal-to-noise ratio: In human-computer interaction, the signal-to-noise ratio represents the ratio of relevant information to irrelevant information in the communication process. In a user interface.
The "information" involved in the signal-to-noise ratio can be anything - including textual content, visual elements or motion, and essentially anything the user has to deal with counts as information or noise. To increase the efficiency of communicating information through our designs and help users accomplish their tasks, we want to achieve a special database high signal-to-noise ratio. 01 Information or Noise? Although the definitions of information and noise are simple, in practical design it is not always easy to tell the difference. Not every user has the same goals, so the exact meaning of "information" and "noise" will vary.
Information for one user may be a distraction to another. Therefore, the signal-to-noise ratio of the UI interface may be higher or lower, depending on who is looking at it and what that user is trying to do. United's home page contains elements that may be informative in some cases and noise in others. United's home page is the starting point for some special database different missions. E.g: Book a flight Make a flight reservation Find details about booking flights For users who want to book a new flight, the blue Book Travel box in the middle of the page will be the strongest message - the part most relevant to the user.
