ISO/IEC TS 20071-15:2017对扫描人类直接使用的视觉信息的应用程序的用户界面的各个方面提供了指导，包括: -启动扫描应用程序； -设置用户偏好并配置扫描应用程序； -识别用户当前感兴趣的信息类型； -定位用户感兴趣的视觉对象； -通过扫描视觉对象创建静态图像； -识别视觉对象提供的信息内容； -处理扫描信息并将结果输出给用户。 ISO/IEC TS 20071-15:2017通过解决不同环境中不同用户的用户可访问性需求，提供了更高的可访问性。 ISO/IEC TS 20071-15:2017包含适用于各种设备的指南，包括: -专用于扫描和处理视觉信息的专用设备； -移动设备（如智能手机和平板电脑）； -具有摄像功能的通用计算机； -具有扫描功能的办公机器。 ISO/IEC TS 20071-15:2017包含适用于各种类型软件的指南，包括: -独立扫描应用程序； -应用包括扫描功能； -（扫描）与其他应用程序互操作的应用程序。 ISO/IEC TS 20071-15:2017包含可用于以各种方式输出扫描信息的指南，包括: -音频输出； -视觉输出； -触觉输出； -在执行扫描的应用程序内存储供将来使用的信息； -电子输出（至其他应用、系统或设备，包括直接连接和通过互联网连接的应用、系统或设备）。 ISO/IEC TS 20071-15:2017没有: -适用于不受人类直接控制的全自动扫描； -适用于扫描视觉信息以编辑图像或仅显示图像的应用程序； -为扫描涉及的特定硬件设备的设计提供指导； -就可识别的特定物体或用于识别这些物体的特定软件提供指导； -为识别特定类型对象的软件的内部功能提供指导。 ISO/IEC TS 20071-15:2017旨在供包括用户控制扫描功能的应用程序开发人员使用。它并不期望应用程序包含所有这些功能。它可以用于应用程序提供的那些功能。

ISO/IEC TS 20071-15:2017 provides guidance on various aspects of the user interface of applications that scan visual information that are used directly by humans, including: - initiating the scanning application; - setting user's preferences and configuring the scanning application; - identifying the types of information currently of interest to the user; - locating visual objects of interest to the user; - creating a static image via scanning the visual object; - identifying the information content provided by the visual object; - processing scanned information and outputting the results to the user. ISO/IEC TS 20071-15:2017 provides increased accessibility by addressing the user accessibility needs of diverse users in diverse contexts. ISO/IEC TS 20071-15:2017 contains guidance that can be applied to a variety of devices, including: - specialized devices that are dedicated to scanning and processing visual information; - mobile devices (such as smartphones and tablets); - general purpose computers with camera capabilities; - office machines with scanning functions. ISO/IEC TS 20071-15:2017 contains guidance that can be applied to various types of software, including: - stand-alone scanning applications; - applications including scanning functionalities; - (scanning) applications that interoperate with other applications. ISO/IEC TS 20071-15:2017 contains guidance that can be used for outputting scanned information in various modalities, including: - audio outputs; - visual outputs; - tactile outputs; - storing information for future use within the application performing the scanning; - electronic outputs (to other applications, systems, or devices including those directly connected and those connected via the Internet). ISO/IEC TS 20071-15:2017 does not: - apply to fully automated scanning that is not under direct human control; - apply to applications that scan visual information for editing an image or just displaying it; - provide guidance on the design of specific hardware devices involved in scanning; - provide guidance on the specific objects that can be recognized or the specific software used to recognize these objects; - provide guidance on the internal functioning of software that recognizes specific types of objects. ISO/IEC TS 20071-15:2017 is intended for use by developers of applications that include user controlled scanning functionalities. It does not expect that an application includes all of these functionalities. It can be used for those functionalities that an application does provide.
