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.
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?
Example: www.testq.com
