The document discusses principles of interactive design including consistency, visibility, learnability, predictability, and feedback. Consistency keeps elements consistent to give users familiarity, visibility guides users through tasks and actions, learnability measures how effectively users can use a product, predictability makes users confident in what they can accomplish, and feedback answers questions about status and outcomes. Examples of websites that demonstrate these principles are provided.

Design

2.Visability
3.Learnability
4.Predictability

2. Consistency
 Differences in design can draw attention but also
distract the users from the message you are trying
to communicate.
 Keeping elements consistent give users the feeling
of authenicity.
Example: www.facebook.com

3. Visability
Good visibility, according to David Hogue's principles,
 Lead the user through an interaction
 Guide them through a series of tasks
 Indicate what possible actions are available to
them
 Communicate the context of the situation.
Example: www. Nike.com

4. Learnability
The learnability of a product can be measured in the following ways:
 Effectiveness
 Efficiency
 Satisfaction
 Errors
Example: www. wix.com

5. Predictability
 makes people feel good about what they're using,
 what they're doing and what they'll be able to
accomplish.
Example: www. zillow.com

6. Feedback
Feedback answers questions :
 Location: Where am I?
 Current Status: What's happening-and is it still
happening?
 Future Status: What will happen next?
 Outcomes& Results: What just happened?
