- Visibility – Know state of device and actions available
- Feedback – Sending information back to the user about what action has been done and what has been accomplished
- Constraints – Restricting the possible user actions that can be performed
- Consistency – Design interfaces to have similar operations and use similar elements for achieving similar tasks
- Affordance – Attribute of an object that allows people to know how to use it

HCI Design Principles
- Know your user
– This can be hard when your user group is very general
- Reduce cognitive load
– This concerns designing so that users don’t have to remember large amounts of detail
- Engineering for errors
– Engineering for errors includes forcing a user to prevent him or her from making an error or at least make it more difficult
- Maintain consistency and clarity
– You can maintain consistency by using standard operations and representations and from using appropriate metaphors that help to build and maintain a user’s mental model of the system
User Experience
- Satisfying
- Enjoyable
- Fun
- Entertaining
- Helpful
- Motivating
- Aesthetically pleasing
- Supportive of creativity
- Rewarding
- Emotionally fulfilling
Usability
can be broken down into the following goals:
- Effectiveness – How accurately and completely users can
accomplish tasks
- Efficiency – How quickly users can complete tasks
- Safety – Avoid dangerous situations caused by interaction with
technology
- Utility – Provide enough functionality for users to accomplish
necessary tasks
- Learnability – How easy is it to learn to use technology
- Memorability – How easy is it to remember how to use a
technology once you have learned how to use it
