ISO/IEC 9995 specifies various characteristics of keyboards used by ITE e.g.
a) personal computers, Workstations, computer terminals, VDTs (visual display terminals), typewriters, etc, having an alphanumeric keyboard;
b) calculators, telephones and automated teller machines having a numeric keypad.
The keyboard defined in ISO/IEC 9995 is the conventional linear keyboard, which is physically divided into sections and the sections into zones within which the keys are laid out.
In this part of ISO/IEC 9995, the sections of the keyboard are identified and the general shape and relative piacement of the sections are specified. Spacing of keys and physical characteristics are covered in this part of ISO/IEC 9995 as are the principles goveming the piacement of characters and symbols on keys.
This part of ISO/IEC 9995 specifies a key numbering system which applies to all types of numeric, alphanumeric and composite keyboards of ITE.
This part of ISO/IEC 9995 specifies the principles governing the piacement of characters and symbols on keys used on all types of numeric, alphanumeric and composite keyboards of ITE. Although the keyboard defined by ISO/IEC 9995 may be used for different languages, the specifications are written as applying to Latin languages with a character path from left to right and a line progression from top to bottom.
The primary layout within the alphanumeric zone is established in most countries by a national standard or by national usage. Allocation guidelines are provided in ISO/IEC 9995-2. Complementary layouts are specified in ISO/IEC 9995-3.
This part of ISO/IEC 9995 defines characteristics related to interface 1 in figure 1.
ISO/IEC 9995 specifies the allocation of functions (graphic characters and/or control functions) to keys. The graphic characters and the control functions have been given common names intended to be familiar to the users of a keyboard. In general, keyboards are not expected to generate coded control functions, but the operation of a control function key may cause a number of coded control functions to appear in data interchange to achieve the desired effect.
The effects of those keys that affect keyboard states are specified in other parts of ISO/IEC 9995.
