The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs. The goal of this interaction is effective operation and control of the machine on the user's end, and feedback from the machine, which aids the operator in making operational decisions. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

Information technology -- User interfaces -- Accessibility of personal computer hardware

ISO/IEC 29136:2012 provides requirements and recommendations for the accessibility of personal computer hardware, to be used when planning, developing, designing and distributing these computers. While it does not cover the behaviour of, or requirements for, assistive technologies, it does address connectivity of assistive technologies as an integrated component of interactive systems. Some requirements or recommendations in ISO/IEC 29136:2012 require software support; however, requirements and recommendations that solely focus on software are not included in ISO/IEC 29136:2012.

Information technology -- User interfaces -- Accessible user interface for accessibility settings

People with disabilities (e.g. visual, hearing, physical) can experience difficulties in accessing computers and other information/communication technology (ICT) devices. Accessible user interfaces, as defined in ISO/IEC 24786:2009, can help them to operate computers if they are able to adjust accessibility settings prior to use. If this is not possible, some people will not be able to access these devices without help from another party.

Information technology -- Individualized adaptability and accessibility in e-learning, education and training -- Part 2: "Access for all" personal needs and preferences for digital delivery

ISO/IEC 24751-2:2008 provides a common information model for describing the learner or user needs and preferences when accessing digitally delivered resources or services. This description is one side of a pair of descriptions used in matching user needs and preferences with education delivery (as described in ISO/IEC 24751-1).

Information technology -- Individualized adaptability and accessibility in e-learning, education and training -- Part 1: Framework and reference model

ISO/IEC 24751 is intended to meet the needs of learners with disabilities and anyone in a disabling context. ISO/IEC 24751-1:2008 provides a common framework to describe and specify learner needs and preferences on the one hand and the corresponding description of the digital learning resources on the other hand, so that individual learner preferences and needs can be matched with the appropriate user interface tools and digital learning resources.

Information technology -- Individualized adaptability and accessibility in e-learning, education and training -- Part 3: "Access for all" digital resource description

ISO/IEC 24751-3:2008 provides a common language for describing digital learning resources to facilitate matching of those resources to learners' accessibility needs and preferences (as defined in ISO/IEC 24751-2). This description is one side of a pair of descriptions used in matching user needs and preferences with education delivery (as described in ISO/IEC 24751-1).

Information technology -- User interface component accessibility -- Part 11: Guidance for alternative text for images

ISO/IEC TS 20071-11:2012 applies to all static images that are used in any type of electronic document. It also applies to individual images within a slide show of electronic images. ISO/IEC TS 20071-11:2012 does not apply to moving images (e.g. movies).

Information technology for learning, education and training -- Language accessibility and human interface equivalencies (HIEs) in e-learning applications -- Part 1: Framework and reference model for semantic interoperability

ISO/IEC 20016-1:2014 states the principles, rules and metadata elements for specifying language accessibility and Human Interface Equivalents (HIEs) in e-learning environments. It is structured to be able to support the requirements of applicable jurisdictional domains and in particular that of the UN Convention on the Rights of Persons with Disabilities.

Information technology -- Guidelines for the design of icons and symbols accessible to all users, including the elderly and persons with disabilities

ISO/IEC TR 19766:2007 provides recommendations relating to the design of icons to support accessibility by the elderly and people with disabilities. These recommendations assist accessible implementation of all icons for users. While these recommendations were developed to meet the needs of the elderly and people with disabilities, they can also provide greater accessibility to a wider range of users in a variety of different contexts.
