Operating the Media Player with a Screen Reader
Our current choice of media players, JW FLV Media Player, has many accessibility features, including support for closed captions and closed audio description. It also provides alternate text for control buttons. However, the labels on these buttons can be confusing or misleading. The following is a list of buttons in the Flash media player that are announced by screen readers, and their actual function. Additional objects announced by screen readers (e.g., graphics without labels) have no informative or functional purpose.
| Image of button | Label spoken by screen readers | Function |
|---|---|---|
|
Pause button | Plays or pauses the video (a toggle) |
|
Previous button | Stops the video and returns to the beginning |
|
Full screen button | Shows video in full screen mode (requires mouse click) |
|
Captions button | Toggles captions on and off (requires mouse click) |
|
Audio description button | Toggles audio description on and off (available only on select videos) |
|
Mute button | Increases or decreases Volume (requires a mouse) |
Increasing Font Size
Most browsers provide the ability to increase font size or magnify the content of the browser window with a single keystroke. DO-IT Video Search was carefully created with sensitivity to users' diverse visual needs, and was tested in a variety of browsers with a variety of font sizes and zoom levels to ensure that content scales well and provides a usable experience even when enlarged.
For steps on enlarging the content within various browsers, consult the W3C's page How to Change Text or Colors.
Using the Built-in Access Keys
Shortcut keys are provided for the large font media player control buttons so that they can be easily activated regardless of your current area of focus on the web page. These shortcut keys are defined using the HTML accesskey element, which is implemented differently across different browsers. To activate any of the buttons, use the assigned key (shown in the first table) in combination with the keys appropriate for your browser (shown in the second table). Note that occasionally these assigned key combinations may conflict with key combinations used by browsers, plug-ins, or assistive technologies.
| Button | Access Key |
