ISO/IEC TR 29138-1:2009确定了残疾人的用户需求集合，供标准开发人员在制定或修订标准时考虑。这些用户需求对于信息技术产品和服务的开发人员以及可访问性的倡导者也是有用的。除了识别用户需求之外，ISO/IEC TR 9138—1:2009还确定了残疾人使用信息技术所带来的问题，这些信息导致了这些用户的需求，并将这些用户需求的关系与标准开发者的可访问性因素进行了对比，以考虑ISO/IEC指南71中所发现的问题: <一> 制定标准时满足老年人和残疾人需求的指南。

ISO/IEC TR 29138-1:2009 identifies a collection of user needs of people with disabilities for standards developers to take into consideration when developing or revising their standards. These user needs are also useful for developers of information technology products and services and for accessibility advocates to consider.

In addition to identifying user needs, ISO/IEC TR 29138-1:2009 identifies problems that people with disabilities experience with information technologies that lead to these user needs and identifies the relationship of these user needs with the accessibility factors for standards developers to consider found in ISO/IEC Guide 71: Guidelines to address the needs of older persons and people with disabilities when developing standards.
