[whatwg] input type=ink proposal

[Charles Pritchard]

Has there been prior discussion about an input type="ink" form element?

This element would simply capture coordinates from a mouse (or touch/pen 
input device),
allowing the user to reset the value of the element at their discretion.

InkML is in last call:
http://www.w3.org/TR/InkML/

We could use <trace> elements as the data container:
http://www.w3.org/TR/InkML/#trace

It's a fairly simple element, there's no particular reason why it 
couldn't be widely supported.

Digital signatures, amongst other things, have been common for quite 
awhile, just not
in the browser.


Use Case:

As part of a web form, a user signs their digital signature to confirm 
acceptance of terms.

Use Case:

While filling out an online profile, a user submits a simple doodle as 
their avatar.

Use Case:

To quickly log into an online system, a user scribbles a password,
which their server tests for fidelity to their prior scribbled input.
