为使操作人员得到有用的显示器,必须考虑许多参数。直接观察设计师选用的显示器和市埸上的现有设备,能提供一些指导,但是,每逢作出设计决定的时候,还需依据有关的测试数据。本文归纳了一些较为重要的设计参数,介绍了一些有用的测试数据,并说明了测试情况下的一些特点,可以确定一组测试结果是否与特殊的设计问题有关。关于测试特点的讨论,既可用来鉴定现有的测试结果,又可用来设计新的测试程序,旨在提供有关显示设备分系统或系统设计的数据。
In order for the operator to get a useful display, many parameters must be considered. Direct observation of the designer’s choice of display and existing equipment on the market can provide some guidance, however, whenever design decisions are made and based on the relevant test data. This article summarizes some of the more important design parameters, introduces some useful test data, and explains some of the features of the test case to determine whether a set of test results is related to a particular design problem. Discussions about the characteristics of the test can be used both to identify existing test results and to design new test procedures designed to provide data on the design of the display subsystem or system.
