Hybrid Event Where Only the Room, Not the Stream, Is Captioned

1.2.4 — Captions (Live)

Scenario

Setting

A ride-hailing app's trip booking screen

What’s wrong

Hybrid events where only the in-room feed is captioned, not the web stream.

Example

A QA pass on a ride-hailing app's trip booking screen turns this up: hybrid events where only the in-room feed is captioned, not the web stream.

Why it matters

Deaf and hard-of-hearing participants in live streams, classes, and meetings. The practical effect on a ride-hailing app's trip booking screen: they can't tell what the image or video is showing.

How to test

For hybrid events, check the web stream specifically (not just the in-room screen): if only in-room viewers get captions, the web stream fails.

How to fix

Readable, reasonably accurate real-time captions must run for the entire live event.

Outcome

That one change on a ride-hailing app's trip booking screen means they get the same information as everyone else.

Who is affected

Deaf and hard-of-hearing participants in live streams, classes, and meetings.
