Structure Principle
Navigation within a screen is important
Group things effectively
Align fields effectively

Lock on to the most user's interface structure base on how well it run. 

One of the good example of the structure principle will be FireFox. All  the information and data have been caregorise into sub buttons so due to this, It doesn’t take the information being browsed away. Everything also join in the top and it won't  take must of the interface, in the end the focus is more on the website being viewed.
                                                                  
                                                                                            Simplicity Principle

Your design should be intuitable

Word your messages and labels effectively

Main user interface navigation between projects is very important to design into the most simple operation and communication.
 

 Simplicity Principle tag each game interactions. Let players know how to access and play the game. The player can also visually move around and find out how the game works.

Visibility Principle

Don't create busy user interfaces

Use color appropriately

Follow the contrast rule

                                 Design does not spread and pull attention away from the mainmessage.

                      Interface is clean, not distracting in any way the user organization.IT user colors appropriate to let users know if it is available or can not contact. Interface is not active or debris. every contact is in alphabetical setting, there is no red herring market. Skype has habitualness visibility into their design principles.
                                                                                            
                                                                                                    Feedback Principle

Word your messages and labels effectively

Hold the line

Expect users to make mistakes

Clearly communicate information and change user error.

Base on the feedback principleWhen any change was made a  red flag pop up, will, letting the user know the program has update or change.When the player is idle for a certain period of time, the League of Legends will, brought a warning window. Immediately notify the players of the game made any changes and errors code find.

Tolerance Principle

Expect users to make mistakes

Look at other applications with a grain of salt

Navigation between major user interface items is important

                               the reduction of error and having the interface to become very flexile and wild will be first step.

The tolerance principle base on being flexile  when error  are made by the user. Microsoft Word 2010 will be a good example of this point. It hold a tools of built inside the program by that it allows user to find changes made also if user not happy with the changes, user can just undo them. Microsoft know  that all human being make mistakes and always want   try to fix the changes.

Reuse Principle
Consistency
Set standards
Explain the rules

Designed to focus, on how  to reduce the need to re-learn and how to use the interface consistency and integration of behavior.

The game Left of Dead 2 has use principle of reuse, because  most people already know that a first-person shooter(FPS)'s method of reuse principles. Such as typical WASD keys to move the character, and  the left mouse button is fire your weapon, it is consistent. There is no need to re-learn how to play FPS games is the principle of re-integration.
