| LearnerIn the classroom- Edward is a 15-year-old blind high school student.
- Edward is in a classroom with other students.
- As part of demonstrating an idea, the instructor of the class plays a video for the class to watch. The video is on the web, and the instructor goes to the website to stream it in real-time (that is, the video is not offline).
- The video is composed primarily moving images and diagrams with little narration, and does not have caption or subtitle alternatives.
- Edward needs this video described to him while most of his classmates do not.
Floe's role: At home- Maria is a 22-year-old university student with uncorrectable blurry vision.
- Text needs to be larger for her, preferably in high contrast, and image with fine details need to either be enlargeable with details maintained, or have some text alternative.
- Maris is at home, working on an assignment which requires some research online.
- Maria uses Google to start her research.
- Like many users, she scans for a promising sounding link, and clicks through several before finding something appropriate.
- More problematically, she spends additional time following promising links but ultimately filtering past them because of their usability (e.g., too many images without good resolution or alternatives, or non-adjustable contrast)
