The user interface is one of the most important parts of any program because it determines how easily you can make the program do what you want. A powerful program with a poorly designed user interface has little value. Graphical user interfaces that use windows, icons, and pop-up menus have become standard on personal computers.

 User interface design or user interface engineering is the
design of computers, appliances ,machines, mobile,
communication devices, software applications, and websites
with the focus on the user’s experience and interaction. The goal
of user interface design is to make the user's interaction as
simple and efficient as possible, in terms of accomplishing user
goals—what is often called user-centered design.

3.  User Interface Design is beneficial for both software and
hardware. Some of the benefits of having a good User Interface
Design are:
1.Ergonomics: Ergonomically correct user interfaces prevent
industrial injuries and hence absence due to illness.
2. Fewer errors: Intelligently designed user interfaces drastically
reduce the number of errors and their related costs.
3. Productivity / Save Development time: A better user design
allows reduction of the development time spent due to reduced
iterations and rework and overall better productivity.

5. Customer returning: If customers find a site or product usable,
then the possibility that they use this site / product again
improves drastically.

then the possibility that they use this site / product again
improves drastically.
7. Increase user satisfaction: When systems match user needs,
satisfaction often improves dramatically.

5. 8. Increase market share (competitive edge): The importance of
having a competitive edge in usability may be even more
pronounced for e-commerce sites. Such sites commonly drive
away nearly half of repeat business by not making it easy for
visitors to find the information they need.
This is benefits for user interface.

6.  Therefore to achieve that the software must have a great user
interface which lets you do what need to do (e.g. creating a
project and managing a team) intuitively without you even really
thinking about it.
A good user interface usually constitutes the following:
1.Positioning of elements in places the user expects them
2.Good use of color coding
3.Speed and fast page loads
4.Activity indicators
5.Help and tool tips

7.  Web designers and programmers (including myself) have often
tried to be clever when designing the information architecture
(where things go) in web pages. We often fall down the trap of
trying to be too creative and thinking 'lets try something totally
different' so we design things in such a way that might look cool,
but in reality what happens is the user gets lost and has to re-
learn how to work their way around your application or website.
 There is a good reason why search boxes are often in the top
right, and why navigation is tabbed, and why buttons often look
the same. It's because the user expects them to be like that.
 Users will spend a lot of their time using a Mac or PC and will
expect the search to be in the top right with a little magnifying
glass, and will expect a button to look a certain shape and
change color when they hover over it. Because of these
expectations in order to be a good UX designer you need to just
go 'with the grain' and do what is expected. This will lead to
happy users, and hopefully paying customers.

8.  It's important to use color in your interface. Colors send signals
to the user sub-consciously, so therefore you can make use of
this with things like buttons and links.
 For example, a Submit or Signup button works well in green
because green means "Go" and feels safe. If it was red then
users would hesitate before clicking on it because they would
feel like they might be deleting something. Orange also tends to
work well for a Signup button. A good example of a big, clear,
green signup button. is on In Direo.
 Having a rollover state is good too, and this can be done by
either fading the button with opacity or by setting a different
rollover color (e.g. a lighter shade or perhaps grey). This
indicates to the user that they are over the button and will feel
comfortable clicking it.
 If you want to highlight something on a page, for example an
important notice then a light yellow background can really make
something stand out and draw your users attention.

9.  You need speed to save time! Therefore if your application takes
5 seconds every time someone clicks a button to load a page
then that is BAD! If I want to set up a new project then I want to
get it all set up within about 10 seconds. If half that time is spent
loading the page then I will not bother using that application.
 When I built Project Bubble was thinking about this from day
one. For me being able to create a project and add to-dos
straight away was an absolutely essential feature for the app.
Being a paper and pen guy I had to have something that was as
quick (if not quicker) than just getting out my notepad and writing
down my to-dos, so this was all taken in to account when
designing the UI for Project Bubble.

10.  If you are using AJAX to load pages then you must utilize
loading GIFs or your users will not know anything has happened.
It's important for your users to see that something is happening
and they will be patient as long as they can see a loading image.
 I made a transparent loading GIF for this exact purpose, which
you can all download if you want. There are others I use as well
on Project Bubble such as when changing the status between
open and closed projects.

11.  Principle #1: Understand Your Users and Support
Their Goals
 Principle #2: Make Your Interface Easy to Learn and
Enjoyable to Use
 Principle #3: Remain Consistent
 Principle #4: Form a Dialog with Your Users
 Principle #5: Be Problem Free
