Web user experience analysis the seven laws of interactive design

[core prompt] "unless there is a better choice, you follow the standard". What are the rules of law in interactive design that have been accepted as standards,

?

Alan Cooper: follow a standard unless you have a better choice.

as the interaction design of father Alan · Cooper is best known for the phrase "unless there is perhaps a better choice, otherwise it will follow the standard", in the field of interaction design has a lot of laws of time after verification has been recognized as the standard, then you know what way?

1. Fitts Law /

(Fitts’ law) Fitts Law

 

Law: from a starting position to a final target time is determined by two parameters, the distance to the target and the target size (D and W in the picture above), the mathematical formula for T = a + B log2 (D/W+1).

it is 1954 Paul. Fitz first proposed and used to predict the time required from any point to the center of the target location of the mathematical model in human-computer interaction (HCI) and the influence of the design field is the most extensive and profound. The change in the new Windows 8 from the start menu to the start screen can also be seen as an application of the law.

Fitts Law enlightenment:

buttons and so on, you can click the object, you need a reasonable size.

The edges and corners of the

screen are ideal for placing elements such as menus, bars, and buttons, because corners are great targets, and they are infinitely high or infinitely wide, and you can’t pass them over with a mouse. That is, no matter how far you move, the mouse will eventually stop at the edge of the screen and position it on the button or menu.

The

appears in the control menu (right-click menu) next to the object the user is working on. It can be opened faster than a drop-down menu or toolbar, because you don’t have to move to another location on the screen.
