Top 10 UI Design Principles Every UI Designer Should Know
UI design or User interface is a huge part of graphic design. Before you create any mobile application, website or any kind of software you have to create a full design on which programmer will work. This is just like an architect design a structure and finalizes the model before they really build it. That being said there is a small difference between UI Designer and UI Developer. UI designer just designs the interface but an UI Developer is a combination of programming, psychology, and creative design. So, there are some rules which every UI designer should follow. This article gives you a brief on most essential UI Principles.
1. REFLECTIVITY of SYSTEM STATUS
A good system should always keep its user informed about the recent activities on the system. The system should give some proper feedback within a realistic time. For example:
Facebook, Youtube, Twitter gives its users a proper notification feedback. Your mobile gives you a feedback when the battery is low. These are some user-friendly UI.
2. RELATION BETWEEN SYSTEM and THE REAL WORLD
A good system should have the functionality and flexibility to choose from different languages and it must speak the users' language. It must get the words, phrase, and concept rights about the particular language rather than just some system-oriented relations. If a user can use any software, website, device in his/her own language and can relate to the system then it's a great UI.
3. SELF-DETERMINATION and USER CONTROL
User sometimes chooses some system functions by mistake and then there is a need for ''emergency exit''. A good UI system should have these kinds of function something like "undo and redo ".This is an essential part of e-commerce website UI.
4. RELIABILITY and CRITERIA
A user should get a clear idea about the interface. If users wonder whether different words, actions or state mean the same thing or not then it is not a good UI design. For example, we can say that facebook emotion options are the perfect example. When you like something on facebook you saw the like icon and realize it means like. That's a good UI.
There are two kinds of error: slips & mistakes. Slips happen when user try to do one thing but ended up doing another thing. A Very common example is ''typing mistake''. Mistakes happen when user try to accomplish a wrong goal but fulfill the right steps.for example, if a user tries to book a flight but chooses the wrong date. For this kind of problem, a good UI can offer suggestions to the user.
6. ACKNOWLEDGEMENT & RECALL
If a user has to remember every information in order to use the interface then it's not a good UI. A good UI always reduce the user's memory load. Instructions for use the system should be visible and should be easily retrievable when needed. For example, there can be a section in UI which shows the previously visited items.
7. PRODUCTIVITY of USE
Great UI is always understandable by both new and old users.If the experienced and inexperienced user understands the UI easily then there will be an increase of interactions on the system.
8. ARTISTIC and SIMPLE DESIGN
A simple and minimalistic design is always great. A great design should not contain any kind of unnecessary information or design. Every single piece of unnecessary information and design makes the UI more complex.In order to create a great UI design try to make it as simple as possible.
9. RECOGNIZE and RECOVER from ERRORS
Error messages should be expressed in plain languages.It should exactly specify the problem and then suggest a solution.
If a system can be used without any documentation then it's a great design. That being said it is necessary to provide help file and documentation. This documentation should be well-organized and easily searchable.
So, These are the main principles of UI design. If you want to create a great UI design you have to keep these principles in mind.
