Interactivity UI Assignment

Principle Of Simplicity

The simplicity principle deals with turning complex tasks from time consuming and difficult, to quick, simple and easy.

Logic Express

11) Follow The Contrast Rule
10) Use colour appropriately
6) Navigation within a screen is important

Principle of Structure

The structure principle makes sure the UI is organized properly and is familiar and can be understood by the user.

Microsoft Powerpoint

5) Navagation

12) Align fields properly

1) Consistency

Principle of Visibility

The principle of visibility ensures that everything on the UI is set up in such a way so that everything is easy to locate, it is not perplexing  and that it keeps the attention of the user without making them flabbergasted.

5. Navigation between major user interface items is important
If

6. Navigation within a screen is important

14. Justify data appropriately

Feedback Principle

Related Techniques:

13. Expect your users to make mistakes

15. Your design should be intuitable

16. Don’t create busy user interfaces

Feedback is very important because it reassures the user that the software reacts to what they’re doing. (ex. If a website posts a message that your password is incorrect)

Facebook is an example of the feedback principle because it expects users to make mistakes (allows users to delete comments, unlike likes, change passwords, etc.) It’s not a busy interface, everything is well layed out and easy to nagivate.

Tolerance Principle

Related Techniques:

15. Your design should be intuitable

13. Expect your users to make mistakes

4. Explain the rules

Tolerance principle is very important because it allows the user to undo and redo their actions and make mistakes, and the software can handle it and adjust. It allows the design to be flexible and tolerant.

Microsoft word is an example because it allows the users to undo and redo their actions and is very flexible and tolerant (allowing the user to create whatever design they want on their paper) and allowing recommendations. (Paperclip Letter writing helper)

The Reuse Principle

Related Techniques:

7. Word your messages and labels effectively

10. Use color appropriately

17. Group things effectively

The resuse principle is important because it should be simple for the user to navigate throughout the interface with it being easy to remember. The functionality should be considered more than the actual design of the website.

Theberrics.com is a perfect example of a site that demonstrates the reuse principle. It’s a website where they post skateboarding videos. It’s got the latest and most relevant videos posted on the “Daily ops” page (home page) with the “Features” button with all the different types of videos in categories with the latest ones at the top of the page. So the user doesn’t have to remember what video to search for, just the category. The functionality of this site was thought about more than the design, there’s no fancy borders or type, it’s just a black background with the necessary ads and social network connections with the latest videos posted directly in the centre with all of them in categories.
