Methodology

Experienced vision-impaired users tested the remaining eight video players on the following combinations of screen reader / operating system and browser:

A series of tests were undertaken including whether the player’s controls were labelled, button status was announced appropriately and fast-forwarding and rewinding was available to the screen reader user. A video player was deemed to include a show-stopper if the video could not be played– not a failure of WCAG2, but deemed a significant failure. Only one video was excluded at the end of this round of testing: Panopto.
