信息技术.用户界面组件的可访问性.第15部分：扫描视觉信息以各种形式显示为文本的指南

[中文适用范围]： 本文件提供了关于应用程序中用户界面的各种方面的指导，这些应用程序直接由人类使用，并扫描视觉信息，包括： — 启动扫描应用程序； — 设置用户的偏好并配置扫描应用程序； — 识别当前对用户感兴趣的信息类型； — 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； — 识别由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。 本文件通过解决不同上下文中多样化用户的可访问性需求，提高了可用性。 本文件包含的指导可以应用于各种设备，包括： — 专门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）； — 具有摄像头功能的一般用途计算机； — 带有扫描功能的办公机器。 本文件包含的指导可以应用于各种类型的软件，包括： — 独立的扫描应用程序； — 包括扫描功能的应用程序； — （扫描）与其他应用程序、系统或设备（直接连接或通过互联网连接） interoperating applications. 本文件可用于以多种方式输出扫描信息，包括： — 音频输出； — 视觉输出； — 触觉输出； — 在执行扫描的应用程序中存储信息以供将来使用。 本文件不包括以下内容： — 不受人类直接控制的全自动扫描； — 用于编辑图像或仅显示图像的扫描应用程序； — 扫描硬件设备的设计指导； — 具体可以识别的对象或识别这些对象所用的具体软件的指导； — 具体类型对象识别软件内部功能的指导。 本文件适用于开发包含用户控制扫描功能的应用程序的开发者。它并不期望一个应用程序包含所有这些功能。它可以用于那些确实提供的功能。 [外文原描述]： 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.
