Introduction to the man-machine interface design

due to the influence of traditional concepts, for a long period of time, the man-machine interface has not been paid great attention in software development staff, thought that this is purely to please users of low activity, without any practical value. The sole criterion for evaluation of an application software quality high and low, is to see whether it has powerful function, can help users to complete their task successfully.

in recent years, with the rapid development of computer hardware technology, the computer storage capacity, speed and reliability of the technical performance indicators have made obvious progress, computer hardware production capital has fallen sharply, becoming increasingly prevalent in the personal computer. A new generation of computer users, application software of manipulability and software control comfort and so on puts forward higher requirements on application software in addition to the stage to see the software has a strong function, more period see application software can as far as possible to provide a relaxed, happy, feel good control environment. This suggests that the quality of the human-computer interface has become a big topic, friendly HMI touch screen design has become an important part of the application software development.

the design principles of man-machine interface

the stand or fall of man-machine interface design and the designer's experience has a direct relationship, some principles for almost all good man-machine interface design is applicable, generally from the interoperability, information, display, data entered into consideration:

principle 1: in the same user interface, all the menu selection, command entered, data display and other functions should be to maintain the consistency of the style. Style consistent interface can give a person a kind of concise and harmonious aesthetic feeling.

principle 2: to all possible damage, insisted that the user to confirm, such as questions & other; Are you sure & hellip; … 吗? ” Etc. , for the majority of action should be promised to restore ( UNDO) And a tolerant attitude error to the user.

principle 3: the user interface should be able to response to the user's decision to make timely, progress dialog, mobile, and thinking about the efficiency of the biggest may reduce the number of keystrokes, shorten mouse interval, avoid the user to produce the feeling of uncertain.

principle 4: man-machine interface should provide context-sensitive help system, let the user get help in time, as far as possible using short verbs and verb phrases, the command.

principle 5: reasonable and efficient use of the display screen. Show only the information related to the context, allow users to the visual environment maintenance: such as amplification, narrow images; With a window to separate different kinds of information, only shows meaningful error messages, avoid too confusing cause troubles users for data.

principle 6: ensure that information is displayed and feed the data into the way of harmony, to minimize the user into action, hidden hide under current state cannot choose command, allow users to customize entered, type can delete no practical significance in allow users to control the interaction process.

these principles are of man-machine interface design should follow the principle of the most basic, there are many design principles should be considered, such as how to correctly use color, etc.
