In this section, we look at the ease of understanding visual codes. It is, however, important to remember that sound codes can be just as useful in many instances as visual codes. One advantage of sound codes is that it is not necessary to be in a par­ticular workplace in order to notice them, and […]

The grammar to be used in this connection must be very simple. It should consist only of: • Nouns • Adjectives • Verbs Nouns should be used to specify different physical objects such as generators, motors, transformers, and switches. The verb is used to give the condition of the noun—for example, on, off, running, open, […]

Semantics specify what the different characters mean. In this case, the semantics are summarised in Figure 3.12. The notion of codes is used here as an overall concept 1. Nonfigurative codes, which consist of several small elements. The indi­vidual elements have no meaning in themselves, but when combined they have common unambiguous meanings. The most […]

Different sorts of traditional symbols are used by humans to convey a particular meaning; for example, the cross represents Christianity for a large proportion of humanity. The alphabet can be used to build up different definitive meanings using various systematic rules. It is important in the construction of an artificial language that all the users […]

In older types of control rooms, every variable was represented by its own instru­ment, regulator, or control device. These were placed together on a panel. Over the years, various ergonomic rules for the design of panels have been produced with the aim of achieving the best possible operational conditions. The development of VDUs and computers […]

• Whether data should be presented in columns or rows depends on what is more natural for the task in question. • Letters are better for identification than numbers. • Numbers should be arranged in as few columns as possible. The design of pictures and the positioning of text within each frame is usually a […]

The following section presents some brief recommendations on the requirements, which should be placed on CRTs, currently the most common form of informa­tion presentation aid in the computer control system. The basic design features of a CRT are that the information shall be visible and easy to read. It is important to choose a suitable […]

A visual display unit is the collective term for information devices designed for several different purposes (for example, for reading off temperature, shaft speed, instruction, information on handbook data). There are many different types of VDUs, of which the most common is the CRT. But there are many other types, such as liquid crystals, plasma […]
