Summary

An API for web applications to make use of advanced handwriting recognition
services (e.g. those on operating systems) to recognize text from
handwriting drawings (inks) in real time. In this context, handwriting
drawing means the temporal and positional information used to describe a
human handwriting process.

Risks

Interoperability and Compatibility

Different browsers (and operating systems) will expose different underlying
implementations and produce different outputs given the same input. We
think this is acceptable given the implementation is machine-learning
based, and it is not feasible or desirable to precisely specify the
expected output for a given input in a standard. In the past, we have taken
this approach for the Web Speech and Shape Detection APIs.

Debuggability

N/A. Existing DevTools tooling works for this feature.


Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_platform_tests.md>
?

No. Full coverage relies on platform-specific implementation. WPT only
tests failure cases.
