Accessibility statement

AbacusPlay should work for every child and grown-up, whatever their eyes, hands or devices. Here is what we do and what we still need to fix.

Our goal

We aim for WCAG 2.2 level AA on every page: lessons, practice, tests, games and the online abacus.

The abacus without a mouse

• Press Tab to reach the abacus, then use the left and right arrows to pick a rod, the up and down arrows to add or take away one, or a digit key to set that rod.
• The number on the abacus is given to screen readers in the abacus’s label, and lesson questions and answers are announced as they change.
• On the finger abacus, the up and down arrows change the number, Page Up and Page Down by ten.

Not by colour alone

The value of a bead is printed on it as dots (five on a top die, one on a bottom die) as well as shown by its colour, and the number of each rod can be shown underneath in a bubble.

Other features that help

• Every spoken line also appears as text beside the guide. Voices start only after the welcome pop-up (its switch turns them off), and the speaker button at the top turns them off at any time.
• If your device asks for reduced motion, the dice slide without hops and the celebration labels stay still.
• Buttons are large, games work on touch screens with a big number pad, and nothing in a children’s game is timed so tightly that it cannot be finished.

Known limitations

The talking clips of PlayBuddy and PlayType have captions but no audio description yet, and Bead Balloons needs sight to read the beads; a version that reads the number aloud on request is planned.

Tell us about a barrier
