14、em for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees co

15、llaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standa

16、rds are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication

17、 as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such pate

ISO/IEC 13066 consists of the following parts, under the general title Information technology Interoperability with assistive technology (AT): Part 1: Requ

19、irements and recommendations for interoperability The following parts are under preparation: Part 2: Windows accessibility API Technical Report Part 3: I-Accessible-2 accessibility API Technical Report BS ISO/IEC 13066-1:2011 ISO/IEC 13066-1:2011(E) ISO/IEC 2011 All rights reserved vIntroduction Int

20、eroperability involves the ability to use assistive technology (AT) to add to or augment existing components of information technology (IT) systems. Interoperability between AT and IT is best facilitated via the use of standardized, public interfaces for all IT components. This part of ISO/IEC 13066

21、 provides a basis for designing and evaluating interoperability between IT and AT. It formalizes the layered architecture of hardware-to-hardware, hardware-to-software, and software-to- software connections that have long been implicit in the IT definitions of ISO/IEC JTC 1. It also recognizes the c

22、entral role that accessibility application programming interfaces (accessibility APIs) play in aiding this interoperability. This part of ISO/IEC 13066 identifies a variety of APIs that are described further in other parts of ISO/IEC 13066. These APIs can be used as frameworks to support ITAT intero

24、C 13066 defines the responsibilities of different information technology (IT) and assistive technology (AT) functional units in supporting interoperability. It recognizes that AT can be provided both as functional units that are installed or otherwise connected to a system or can be utilized by bein

25、g provided as a service which is accessed via communications connections. It bases these responsibilities on fundamental IT definitions of major types of functional units. It focuses on the utilization of standard, public interfaces for functional units and on the provision of accessible documentati

26、on of their capabilities. This part of ISO/IEC13066 recognizes that IT is implemented both in conventional computer systems and as a major component of other systems within the wider scope of information and communications technology (ICT). This part of ISO/IEC 13066 recognizes the fundamental role

27、of operating systems and application programming interfaces (APIs), in managing interoperability, and in providing guidance to developers of other functional units. It also recognizes that different operating systems will have their own standardized methods of supporting interoperability. This part

28、of ISO/IEC 13066 does not define or require specific technology, commands, APIs, or hardware interfaces. It defers to other existing standards and supports the development of new standards in these areas. It identifies a variety of common accessibility APIs that are further described in other parts

29、of ISO/IEC 13066. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 accessibility API set of programming interfaces designed specifically to provide accessibility services NOTE An accessibility API is a special instance of an API. 2.2 accessibi

30、lity services services provided by an operating system or other platform software, commonly in the form of APIs (application programming interfaces) that are used by software to expose information about the user interface and events to assistive technologies and that provide two-way communication wi

31、th assistive technologies, including exposing information about objects and events NOTE Accessibility services might provide additional information used by assistive technologies, e.g. about operating system status.
