Re: Canvas based signature block

Hi Corrine,

Have you had a look at DocuSign? They don't require a hand-written signature and, in fact, provide you with fonts that emulate a signature. We've assessed their platform and found them very accessible.

SC 2.1.1 Keyboard has one exception, however: "except where the underlying function requires input that depends on the path of the user's movement and not just the endpoints." But I feel like signing a document is a critical function and absolutely needs to work. Check out DocuSign. If that doesn't work for you, there's not a lot you can do with <canvas>. You can provide text alternatives, add actionable elements to it, make it work with the keyboard, but I don't know how a user could make a signature without typing.

I hope this helps!

Subject: [WebAIM] Canvas based signature block

We use Qualtrics and have a survey which requires a signature block. The signature block is a canvas element and requires visual interaction.

What are some alternatives that others have used in place of this inaccessible option?
