Feedback

17
Q

simple and useful explanation of how something works

22
Q

Users spatial correspondence between the layout of the controls and the devices being controlled to determine how to use them (arrow buttons on a claw machine)

System should always keep users informed about what is going on, through appropriate feedback within reasonable time

A

Visibility of System Status

27
Q

Follows real-world conventions, making info appear in a natural and logical manner

A

Match Between Systems and the Real World

28
Q

Users often choose system functions by mistake and will need a clearly marked “emergency exit” to leave the unwanted state without having to go through an extended dialogue

A

User Control and Freedom

29
Q

Support undo and redo

A

User Control and Freedom

30
Q

Users should not have to wonder whether different words, situations or actions mean the same thing

A

Consistency and Standards

31
Q

Follow platform conventions

A

Consistency and Standards

32
Q

Minimize the user’s memory load by making objects, actions and options visible

A

Recognition Rather than Recall

33
Q

Accelerators (unseen by the novice user) may often speed up the interaction for the expert user such that the system can cater to both type of users

A

Flexibility and Efficiency of Use

34
Q

Allow users to tailor frequent actions

A

Flexibility and Efficiency of Use

35
Q

Dialog shouldn’t contain info that’s irrelevant or rarely needed
