使人/系统界面对话真正易懂确实是80年代的一个挑战。使系统用户友好需要的不仅仅是在人/系统界面中添加英语。人/系统界面可以使用很多新功能，比如颜色、图形、触摸屏、特殊键盘、光笔、语音识别和语音合成。现在有智能终端、哑终端和各种类型的专用显示器。这些功能的存在并不意味着人/系统界面得到了改善。 只有在适当的情况下进行适当的应用，才能使系统更加友好。驱动这些不同设备的软件架构有机会产生更大的改进。正确的软件体系结构将为操作员提供更快的响应，以及更好、更有意义的显示，并将更快地对操作员的操作做出反应。必须从一开始就理解并将接口人员的需求设计到计算机中。将计算机辅助指令等功能结合在一起，计算机实际上会教操作员如何工作，这是使系统非常友好的一步。 长输入形式或短输入形式之间的选择，计算机会提示操作员，或者操作员可以自由地只键入必须键入的内容，从而增强界面的实用性。系统中可以设计输入数据诊断和纠错软件，以破译操作员可能犯下的错误，并自动纠正这些错误。事实上，我们可以做很多事情。引文:德克萨斯州休斯顿ASHRAE学报第88卷第1部分研讨会

Making the man/system interface dialogue truly understandable is indeed a challenge of the 80's. Making the system user friendly takes more than just adding the English language to the man/system interface. There are many, many new features the man/system interface can use such as color, graphics, touch screens, special keyboards, light pens, voice recognition, and voice synthesis. There are now smart terminals, dumb terminals, and specialized displays of all types. The existence of these features does not conclude that the man/system interface is improved. Only proper application in a proper situation will make the system more user friendly. The software architecture which drives these different devices has ap opportunity to yield an even greater improvement. The proper software architecture will give quicker response to the operator, as well as better and more meaningful displays, and will react to the operators' actions much more quickly. The needs of the interfacing human must be understood and engineered into the computer from the beginning. Incorporating such features as computer-aided instructions, where the computer actually teaches operators how to do their job, is a step in making the system very friendly. The option between long input form or short form where the computer prompts the operator, or the operator has the freedom to only type exactly what has to be typed, enhances the utility of the interface. Input data diagnostics and error correcting software can be designed into the system in order to decipher the errors that the operator may have made, and to make the correction of these errors automatically. Indeed, much can be done.
