An interface allows users to interact with and communicate with a system. It is an essential part of software design as it determines how users access and utilize the system's features. A poorly designed interface can prevent users from being able to use the system. The interface design process involves analysis, prototyping, evaluation, and implementation. Key principles for interface design include making the interface familiar to users, consistent, minimizing surprises, allowing for error recovery, providing guidance, and accommodating diversity among users.

1. Interface Design
JahanZaib Afzal

2. Interface
“ An Interface is a way that enable the
user to interact and communicate with the
system”
Connect with any system we are using an
interface.
If a user want to use the functionality of the
system then it must be interact with the interface.
For-example
Window 8 Desktop
We interact our laptops,pc,,mobliles, tabs..etc with
the help of desktop.

3. Interface Design
Interface design is an
essential part of the overall software design
process. If a software is to achieve its full
potential, so it is essential its interface should
be designed expectations of the users. So
interface design is critical process but its
depend upon the requirement of the user.
A poorly designed user interface means that
user will unable to access the feature of the
system.

Design Prototype
Interface Evaluation
Implement Interface

7. Interface Design Principles
1. User Familiarity
2. Consistency
3. Minimal Surprise
4. Recoverability
5. User Guidance
6. User Diversity

8.  User Familiarity
The interface should use terms and
concepts drawn from the experience of the people who will
make most use of the system.
 Consistency
The interface should be consistent in that
wherever possible, comparable operations should be
activated in the same way.
 Minimal Surprise
User should never be surprised by
the behavior of a system.

9.  Recoverability
The interface should include mechanisms
to allow user to recover from errors.
 User Guidance
The interface should provide
meaningful feedback when errors occur and provide
context-sensitive user help facilities.
 User Diversity
The interface should provide
appropriate interaction facilities for different types of system
users.
