NoldusViso is a web application and works with the accessibility features of your browser and operating system, such as zoom, high-contrast settings and screen readers. This chapter lists the features NoldusViso adds and the settings you can change.

1. Use NoldusViso with the keyboard

• Press Tab and Shift+Tab to move between controls; the focused control is outlined.

• Use the Skip to main content link, the first stop on every page, to jump past the navigation.

• Dialogs keep the keyboard inside them while open. Escape closes a dialog, a menu or a tooltip.

• After you open another page, the keyboard starts at the page's content.

• Hold Alt+Shift (Ctrl+Shift on macOS) to show the navigation shortcuts, then press the letter shown.

• Hold Space or Enter on the push-to-talk button to talk.

• To move an event on the timeline without dragging, select it in the annotation log (Tab to it, then Enter), move the playhead to the new time, and choose Move to playhead.

• To reorder streams in a composed download without dragging, use the move buttons on each stream.

• Home has an All pages list that links to every page you can open.

2. Turn single-key shortcuts on or off

While coding, single letter, number and symbol keys add events, tasks and subjects. If you use speech input, or press keys by accident, turn them off in User preferences → Single-key shortcuts. Shortcuts that use Ctrl or Alt, and Space, Enter and the arrow keys, keep working.

3. Turn live updates on or off

On Home and Observe, the session list, its recording timers and the upcoming events update on their own. If changing content distracts you, turn this off in User preferences → Live updates. The lists then change only when you select Refresh list or open the page again, and a recording shows Recording instead of a timer. Live video and the timeline keep updating.

4. Adjust the display

• Choose a light or dark theme, or follow your system, in User preferences → Theme.

• Zoom with your browser up to 200%, or use a narrow window: pages reflow without scrolling sideways.

• Text, controls and status colours meet the WCAG AA contrast levels in both themes. Status indicators combine colour with text, an icon or a shape.

• A sound-wave icon on a video tile shows that audio is coming from that source.

5. Use a screen reader

Every page has its own title and a main heading, and pages use landmarks (navigation, main content) so you can jump between areas. Controls have names, and messages such as saved changes and notifications are announced without moving the keyboard focus.

6. Session timing

You are signed out after 8 hours without activity, or 24 hours after signing in. Five minutes before an inactivity sign-out, NoldusViso asks whether to stay signed in; one click keeps you signed in.

7. Recorded media

Video and audio in NoldusViso are recorded by your own cameras and microphones. NoldusViso does not add captions or audio description to them.
