Canvas or WebGL App With No Keyboard Command Layer

2.1.1 — Keyboard

Scenario

Setting

An online spreadsheet's toolbar

What’s wrong

Canvas/WebGL (3D graphics code) apps with no keyboard command layer.

Example

<div onclick="submitForm()">Submit</div>

Why it matters

Blind users, people with motor disabilities, and anyone operating the interface without a pointer.

How to test

Tab to canvas/WebGL app controls: if there's no keyboard command layer at all for its functionality, it fails.

How to fix

Add a keyboard command layer for canvas/WebGL (3D graphics code) functionality (or an equivalent UI).

<button onclick="submitForm()">Submit</button>

A native button is focusable and triggers on Enter/Space automatically; a div needs all of that added by hand.

Outcome

On an online spreadsheet's toolbar, this barrier is gone for blind users, people with motor disabilities — they get the same result as anyone else here.

Who is affected

Blind users, people with motor disabilities, and anyone operating the interface without a pointer.
