General Accessibility Guidelines
在社交媒体平台上有不同的可访问性选项. University 帐户必须确保最大程度地访问社交帖子. The following guidelines should be used when posting.
Authoring Content
Write in plain language. Remember that viewers won't necessarily know what acronyms 代表，或有科学背景，理解技术术语或 jargon. 如果你在说话，考虑一下你会如何表达你的帖子可能会有所帮助 to a 14 year old high school student. Some viewers might be!
Alternative Text
大多数社交媒体平台允许你将文字“替换”为图片来描述内容 图像，图形和图表的人使用辅助技术，如屏幕 readers.
在社交媒体上发布帖子时，考虑一下没有附件的帖子会是什么样子 image. 用户接收到的信息是否与图像接收到的信息相同 visible?
纯粹的装饰性图片，不会给帖子增加信息，也不需要 be described in alt tags. However, such images should be provided with null (or empty) alt text (alt="")，以便辅助技术(如屏幕阅读器)可以忽略它们.
Video captioning
为了便于访问，发布到社交媒体上的视频应该总是包含字幕. 这些可以是“封闭标题”(可以打开和关闭)，或“开放标题”。 (text embedded in the frames of the video that can't be removed).
Youtube, Facebook, Zoom和越来越多的其他平台现在提供自动 captioning, which is performed by computer AI. Automatically generated captions range in accuracy from about 70% to roughly 90%. These captions are a good start, but for 完全符合要求，它们应该由人工编辑，以提高准确性.
没有口语内容的视频应该包含“音频描述”，这是一种口语 为那些看不到视频的人描述视频视觉元素的轨道. If 这是不可能的，那么在帖子中描述视频内容的文本可以 be helpful. 例如:“视频描述:网赌平台纽科姆校区的航拍镜头， 包括亨廷顿野生森林、阿迪朗达克解说中心和阿迪朗达克公园 Ecological Center."
现场或实时字幕不能由计算机提供，只能执行 by a human. Typically, live captioning services are provided by a paid service.
Animated GIFs
gif动画需要暂停(Facebook, Twitter和越来越多的其他网站) social media platforms now provide this as built–in functionality). They should not 闪光或闪烁的速度快到足以成为癫痫的潜在诱因(少于3 flashes/flickers per second).
此外，要小心包含条纹或格子的图案 than 5 light/dark pairs going in any direction.
不应该依赖gif动画来传达无法获得的信息 otherwise in the post. Consider what the post would look like without the GIF. Can viewers still understand everything you want them to?
Emojis/Emoticons
图形表情符号通常带有嵌入式描述，所以文本到语音屏幕 readers will describe them. When using multiple emojis, leave spaces between them and use them judiciously.
当使用基于文本的表情符号时，例如:D，文本转语音屏幕阅读器无法使用 understand them. They will describe the symbols individually (such as 'semi-colon D').
Both of these are best used sparingly. When using emojis or emoticons, consider how 如果观看者正在使用屏幕阅读器或正在使用屏幕阅读器，他们就会感知到您的内容 otherwise unable to see the image.
Hashtags
对于包含多个单词的标签，每个单词都应该大写(这是 sometimes known as ‘CamelCase’). Capitalizing each word lets text-to-speech screen readers understand how to read the hashtag. For example: instead of #allinthistogether, 屏幕阅读器会尝试将其处理为单个单词，使用# allinthistotogether. 大写字母允许屏幕阅读器识别一个单词的结尾和 beginning of the next. This is also easier on people who have low vision or visual processing issues.
Decorative Text
在社交媒体上使用装饰性文字和符号有时很流行. For example: ©olor instead of color.
在此之前，请记住，每个符号都是由计算机处理的 its own meaning. A computer will not read © as 'C' the way a human eye can. A viewer 使用文本转语音屏幕阅读器将难以理解这些内容.
