Alt Text: What to Write

nngroup.com/articles/write-alt

Did you know that you should end your alt text with a period?

"End alt text with a period, even if it isn’t a full sentence. The period ensures that the screen reader pauses after reading the alt text."

Nielsen Norman GroupAlt Text: What to WriteImages are decorative, functional, or informative. Skip alt text for decorative. Describe the action for functional. Convey the message for informative.

@cybeardjm This is a good tip, thank you!

I was already doing this, but didn't know it was useful.

@cybeardjm This is absolutely powerful helpful guidance. I am improving my alt-text practice all the time.

@cybeardjm a few dozen more posts like this and I might be marginally competent at making alt text. Next post on the topic, are there any goofy keys I shouldn’t use because it freaks out a screen reader? Any other weird things like how it paces the words or will it do a funny accent if something is in the wrong bracket/parenthesis?

@Buthowhighishigh Am not able to answer, but @stefan might have leads to answer this.
I'd say, the KISS method is the best way: Keep It Simple, Stupid! It works all the time ;-)
But, sure, outside of English, what about special characters (e.g. I know many/most/all emojis should be avoided)?

@stefan @cybeardjm @Buthowhighishigh

maybe slightly OT, but I was told once that using those (ノಠ益ಠ) 🄵🄰🄽🄲🅈 𝓤𝓣𝓕 𝓯𝓸𝓷𝓽 𝓰𝓮𝓷𝓮𝓻𝓪𝓽𝓸𝓻𝓼🎀 ★·.·`¯´·.✴ for your username can be a right old PITA for screen reader users.

@axwax @stefan @Buthowhighishigh Indeed - not sure if many use them for alt descriptions though...

@SofaKingHigh I can tell you what not to use in alt-text.

For one, don't put line breaks into your alt-texts. It doesn't matter whether Mastodon renders them. A lot of things in the Fediverse that aren't Mastodon don't render them.

Besides, don't use the quotation marks on your keyboard. They may irritate certain frontends from rendering them as " to ending the alt-text prematurely because they take the first quotation mark in an alt-text for the end of the alt-text.

@cybeardjm how about screen readers actually improve their screen reading experience instead? This is a rubbish "api". What am I missing? Why is _not_ making a pause when reading alt text the default?

@dominykas @cybeardjm It isn't a topic I know in much detail but I had the same reaction. If a pause after the alt text is always desirable, could the software just do that?

@cybeardjm i have been lazy about this, thank you for the knowledge drop =)

@cybeardjm I did not know and have now been taught! Cheers

@cybeardjm much simpler for the screen reader, which 'knows' it is reading alt text to just pause at the end by default.
