23、the International Electrotechnical Commission) form the specialized system 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 part
24、icular fields of technical activity. ISO and IEC technical committees collaborate 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 esta
25、blished a joint technical committee, ISO/IEC JTC 1. International Standards 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 techn
26、ical committee are circulated to national bodies for voting. Publication 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 an
27、d IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24751-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 36, Information technology for learning, education, and training.

40、 droits rservs viiIntroduction ISO/IEC 24751 is intended to facilitate the matching of individual user needs and preferences with educational digital resources that meet those needs and preferences. It is intended to address mismatches between personal needs and preferences caused by any number of c
41、ircumstances, including requirements related to client devices, environments, language proficiency or abilities. The terms and definitions within ISO/IEC 24751 are not judgmental but functional; the purpose is not to point out flaws in educational digital resources with respect to accessibility and
42、adaptability, but to facilitate the discovery and use of the most appropriate content components for each user. In ISO/IEC 24751, it is recognized that learners experience a disability when there is a mismatch between the learners needs (or preferences) and the education or learning experience deliv
43、ered. Disability is therefore not viewed as a personal trait but as a consequence of the relationship between a learner and a learning environment or resource delivery system. An individual who is blind is not disabled when the lesson is delivered in audio, but an individual who does not have the ne
44、cessary background knowledge to understand the lesson, or an individual who is listening to the lesson in a noisy environment, is disabled. Given this reframing, a learning environment is accessible when learner needs can be addressed or matched (through adaptation, re-aggregation or substitution of
45、 digital learning resources). Accessibility is determined by the flexibility of the learning environment (with respect to presentation, control methods, structure, access mode, and learner supports, for example) and the availability of adequate alternative-but-equivalent content and activities. The
46、needs and preferences of a user may arise from the users context or environment, the technical requirements of the users device, the tools available (e.g. assistive technologies such as Braille devices, voice recognition systems, alternative keyboards, etc.), the users background, or a disability in
47、 the traditional sense. Accessible systems adjust the user interface or configuration of the learning environment, locate needed resources and adjust the resources to match the characteristics of the resources to the needs and preferences of a user. This part of ISO/IEC 24751 provides a common frame
48、work for additional parts. These additional parts provide two complementary sets of information: a) the description of a learners accessibility needs and preferences, including 1) how digital resources are to be displayed and structured, 2) how digital resources are to be controlled and operated, and 3) what supplementary or alternative digital resources are to be supplied; b) the description of the characteristics of the resource that affect how it can be perceived, understood or interacted with by a user, including 1) what sensory modalities are used in the resource, 2) the ways
