信息技术产品的不同用户拥有不同的能力。有些能力可能永远不会出现在用户身上，因为他们可能生来就没有这些能力。由于教育、成熟、受伤、疾病或年龄的原因，一些能力会随着时间的推移而获得、发展或退化。正如用户可能拥有多种能力的组合一样，他们也可能缺乏多种能力的组合。 ISO/IEC TR 19765:2007介绍了目前用于提供设施和工具的图标和符号，以支持老年和残疾用户对信息技术（IT）产品的需求，并可能构成未来国际标准的基础，该标准将提供图标和符号的推荐集合。 这些图标和符号来自各种来源，包括其他标准、当代软件产品、网站和硬件设备。这些资料来源相互参照，并在参考书目中列出。 ISO/IEC TR 19765:2007中显示的图标和符号按使用方式和方法分类。

Different users of information technology products possess different sets of abilities. Some abilities may not ever be present in a user as they may have been born without them. Some abilities are acquired, developed or deteriorate over time due to education, maturity, injury, illness or age. Just as it is possible that a user possesses a combination of abilities, it is also possible that they may lack a combination of abilities. ISO/IEC TR 19765:2007 presents icons and symbols currently used to provide access to facilities and tools to support the needs of elderly and disabled users of information technology (IT) products, and could form the basis of a future International Standard which would provide a recommended collection of icons and symbols. These icons and symbols have been collected from a variety of sources including other standards, contemporary software products, web sites and hardware devices. These sources are cross-referenced and listed in a bibliography. The icons and symbols presented in ISO/IEC TR 19765:2007 are categorized by modality and method of use.
