INTRODUCTION
User
Interface Design (UI) is nothing so complicated as such .It is just the UI/UX
design and arrangement or the layout of the software or a machine.
OBJECTIVE AND FUNCTIONS
The
main objective of User Interface is to make program, software or machine user
friendly. The User Interface or UI of a device is the look and feel of the
on-screen menu system. How device works, its color scheme, how it responds to
button presses, all of these things is the part of the user interface.
The
user interface of the software deals with the user interface framework. It is
generally the graphics and layouts seen on the screen. Every software has its
own User Interface whether it is a system software or application software,
System software or simply Operating System is the best example to study User
Interface.
HISTORY AND EVOLUTION
(Types)
Earlier
version of operating systems like DOS, MS-DOS, UNIX, etc. uses Command Line
Interface (CLI). CLI was the first ever user interface used. CLI uses command
line input and output which has simple textual look which makes working on CLI difficult.
The user experience on CLI was not so good.
Then
comes our newer version of operating systems like Windows and Linux which
introduced Graphical User Interface (GUI). Everything like color scheme,
layout, mouse button presses are the part of GUI. Operating System keeps on
modifying and improving user experience and interface. Then operating system
for mobile phones launched and use of hardware UI introduced. It covers touch
screen, accelerometer, gyroscope, proximity etc.
How
device works on screen touch, key button press, on changing the altitude of the
device, on moving the device all comes in user interface. Mobile OS are such as
Android, OSX, etc.
The
user wants a good, faster and more efficient user interface.
Now
the question that pops up in one’s mind is How to make a good user
interface?
First
of all, user needs and wills should be kept in mind like intact i.e. what user
exactly wants, etc. The program layout should be simple with minimum
complexion. Unnecessary calculations can be avoided to make efficiency maximum.
The text font size should not be too small or large. Sharp text color like
light text color on light background or dark text color on dark background must
be avoided. Proper coloring of text and objects are done to make text readable
and attractive.
A
good user interface includes a simple and unique design which is comfortable
with user expectation. It contains complete and correct information. Use of
simple and easily understandable meaning, unambiguity, recognizable words. Data
is so displayed that multiple information is distinguished easily and
accurately.
