ISO/IEC 24779系列标准侧重于与数据采集主体的通信。 本文件包含一组象形图、图标和符号，以帮助公众理解使用收集和/或评估面部图像的电子系统的概念和程序。操作员可以使用本文件，并可能使用其他符号和信息。这组象形图、图标和符号旨在: -识别生物识别传感器的类型； -提供与面部图像采集相关的支持说明。 为了提供这一功能，一组象形图、图标和符号包括方向象形图、图标和符号以及动作或反馈象形图、图标和符号。面部图像象形图、图标和符号包括: -面部图像采集； -单身人士； -没有帽子； -没有太阳镜； -中性表达； -竖起头发； -查看方向。 尽管这些象形图、图标和符号是单独呈现的，但这些象形图、图标和符号旨在结合起来，以充分说明面部图像捕获交互。 例如，在海关或移民环境中，由单个象形图、图标和符号构成的程序可以表示为: -乘客排队时的一系列海报； -生物特征识别亭中的一系列过渡帧； -乘客排队时的动画视频或一系列过渡帧； -供乘客排队阅读的指导传单。

The ISO/IEC 24779 series of standards focuses on communication with the data capture subject. This document contains a set of pictograms, icons and symbols to help the general public understand the concepts and procedures for using electronic systems that collect and/or evaluate facial images. Operators can use this document, with the possibility of using additional symbols and information. This set of pictograms, icons and symbols is designed to be used to: — identify the type of biometric sensor; — provide supporting instructions related to facial image collection. To provide this functionality, the set of pictograms, icons and symbols includes both directional pictograms, icons and symbols and action or feedback pictograms, icons and symbols. The facial image pictograms, icons and symbols include: — facial image capture; — single person; — no hat; — no sunglasses; — neutral expression; — hair up; — view direction. Although the pictograms, icons and symbols are presented individually, the pictograms, icons and symbols are intended to be combined to fully illustrate the facial image capture interaction. For example, in a customs or immigration environment, procedures constructed from the individual pictograms, icons and symbols could be presented as: — a series of posters while passengers are in the queue; — a series of transitional frames in a biometric booth; — an animated video or series of transitional frames while passengers are in the queue; — instructional leaflets for passengers to read in the queue.
