Question 4

8 GOLDEN RULES OF INTERFACE DESIGN (Ben Sheiderman)

Answer 4

1.Strive for consistency: knowing that something is coherent or not is very subjective. When something is incoherent, the user does not use it and looks for
alternatives.

2.Universal Usability Search: Regardless of the user characteristics, the design can be used and regardless of the system and hardware with which one is working, it is universal.

3.Informative feedback sample:When you are designing any element, if the user interacts with it, there must be information.

4.Dialogues for closing action: Every time you end the interaction, the user
must be informed of this end. Ex: “Purchase Made”.

5.Error prevention:Where it is seen that the user tends to make errors, we try to prevent future errors. (Ex: Are you sure you want to delete this file?)

6.Easy stock reversal:Ex. Ctrl + Z,remove units from the shopping cart.

7.Maintenance of control by users: It is important that the user feels that they have control. How do you know this? → Testing.

8.Reduced short-term memory load: That the user does not have to constantly remember information.
