USER INTERFACE DESIGN

In the modern world of software development,it is very essential to have a user interface because this is actually the system to the users.
What users want is for developers to build applications that meet their needs and that are easy to use.Thus,the user interface is so important in application development for several reasons.First of all the more intuitive the user interface the easier it is to use, and the easier it is to use and the less expensive to use it. The better the user interface the easier it is to train people to use it, reducing your training costs. The better your user interface the less help people will need to use it, reducing your support costs. The better your user interface the more your users will like to use it, increasing their satisfaction with the work that you have done.

Many technological innovations rely upon User Interface Design to elevate their technical complexity to a usable product. Technology alone may not win user acceptance and subsequent marketability. The User Experience, or how the user experiences the end product, is the key to acceptance. And that is where User Interface Design enters the design process. While product engineers focus on the technology, usability specialists focus on the user interface. For greatest efficiency and cost effectiveness, this working relationship should be maintained from the start of a project to its rollout.

When applied to computer software, User Interface Design is also known as Human-Computer Interaction or HCI. While people often think of Interface Design in terms of computers, it also refers to many products where the user interacts with controls or displays. Military aircraft, vehicles, airports, audio equipment, and computer peripherals, are a few products that extensively apply User Interface Design.

Optimized User Interface Design requires a systematic approach to the design process. But, to ensure optimum performance, Usability Testing is required. This empirical testing permits naïve users to provide data about what does work as anticipated and what does not work. Only after the resulting repairs are made can a product be deemed to have a user optimized interface.

The importance of good User Interface Design can be the difference between product acceptance and rejection in the marketplace. If end-users feel it is not easy to learn, not easy to use, or too cumbersome, an otherwise excellent product could fail. Good User Interface Design can make a product easy to understand and use, which results in greater user acceptance.



There are several principles that are paramount in designing a good user interface.They are:the structure principle,reuse principle,feedback principle,tolerance principle,simplicity principle and visibility principle.

Considering the structure principle, your design should organize the user interface purposefully, in meaningful and useful ways based on clear, consistent models that are apparent and recognizable to users, putting related things together and separating unrelated things, differentiating dissimilar things and making similar things resemble one another. The structure principle is concerned with your overall user interface architecture.

In the reuse principle,your design should reuse internal and external components and behaviors, maintaining consistency with purpose rather than merely arbitrary consistency, thus reducing the need for users to rethink and remember.

In the feedback principle,your design should keep users informed of actions or interpretations, changes of state or condition, and errors or exceptions that are relevant and of interest to the user through clear, concise, and unambiguous language familiar to users.

In the tolerance principle,your design should be flexible and tolerant, reducing the cost of mistakes and misuse by allowing undoing and redoing, while also preventing errors wherever possible by tolerating varied inputs and sequences and by interpreting all reasonable actions reasonable.

In the simplicity principle,your design should make simple, common tasks simple to do, communicating clearly and simply in the user’s own language, and providing good shortcuts that are meaningfully related to longer procedures.

While in the visibility principle,your design should keep all needed options and materials for a given task visible without distracting the user with extraneous or redundant information. Good designs don’t overwhelm users with too many alternatives or confuse them with unneeded information.

There are certain valuable tips for designing a good user interface in software development.These are consistency,set standards and stick to them,expect your users to make mistakes,use color appropriately,understand the user interface widgets,navigation within a screen,design should be intuitable,don’t create busy user interfaces,group things effectively,word your messages and labels effectively
