This article will act as a guide to understand the language a User sees across BrainStation, and how it responds to their browser, choices, and available content.

The Four Surfaces:

The displayed language of BrainStation is decided separately in four places. The first two move together; the last two are independent of them.

• LMS Dashboard:
  • This includes menus, tabs, reports, and buttons across BrainStation.
• Course Player Interface:
  • This includes the course player, navigation, labels, and module names.
• Video Transcripts & Captions:
  • This would be the transcript text and on-screen captions for a course. This language is chosen by the User from the transcript drop-down.
• Knowledge Checks (KC):
  • These are the interactive quizzes in Bigger Brains courses. The displayed language for these follows the chosen transcript language.

Supported Languages:

Transcript and caption availability is independent of this list, it depends on which caption tracks are available for each course.

How Displayed Language is Decided:

The LMS Dashboard and Course Player Interface walk a priority list top to bottom, and used the first language found.

1. A Saved Choice:
   1. This is the language the User previously selected.
2. The Browser Language:
   1. This is used on a first visit from a User when nothing is saved yet.
3. English:
   1. This is the final fallback if the detected language isn't supported by the surface.

The Video Transcripts, Captions, and Knowledge Checks (KC) walk a separate priority list.

1. The User's Saved Transcript Choice:
   1. This language choice is kept from lesson to lesson.
2. The Interface Language:
   1. This is used as the default the very first time, before any transcript choice is made.
3. English:
   1. This is used if the saved transcript choice or interface language are not available as a caption track.

What Follows the Browser & What Doesn't:

Once a User has made choices, here is what each surface tracks.

Example: 

Following a Spanish-speaking User through three moments will show how these pieces fit together.

Fallbacks & Edge Cases: 

What happens when a language isn't fully available?

Unsupported Interface Language:

If the browser reports a language a surface doesn't support, that surface defaults to English.

Missing Transcript or Knowledge Check Translation:

The transcript drop-down only lists languages a given video actually has caption tracks for. If a specific Knowledge Check has no version in the chosen language, the displayed language defaults to English.
