2.3 Wizard (WIZARD) Principles of Use

The processing process for some parts of the application is fixed, the user must enter the operation information in the order specified, and the wizard should be used to make the necessary reference to the user's operation, but the wizard must be used in a fixed process and the processing process should be no less than 3 processing steps.

2.4 System Response Time

The system response time includes two aspects: the time length and the variability of time. User response time should be moderate, system response time is too long, users will feel uneasy and frustrated, and response time is too short sometimes cause users to speed up the operation of the rhythm, resulting in errors. The variability of system response time refers to the deviation from the average response time. Even if the response time is relatively long, low response time variability can also help users establish a stable rhythm. Therefore, in the system response time adhere to the following principles:

Interface design of response time length

0-10 second mouse display to become an hourglass

10-18 seconds by micro-help to show process progress

More than 18 seconds to display the processing window, or show the progress bar

The completion of a lengthy processing should be given a warning message

Variability interface design for response time

The user does not feel not to consider

Users feel a little bit of help providing variability instructions

Easy to be big and time absolute difference Big Show variability hint

2.5 User Assistance facilities

Common help facilities are available in two ways: integrated and additional. The integrated Help facility was initially designed in software, which is contextual, and allows users to directly select topics related to the actions they want to perform. By integrating help facilities, you can shorten the time that users get help, and increase the friendliness of the interface. Additional help facilities are added after the system is built. It is usually a weaker online help than the query capability.
