Chrome Extension v0.3.8 (superseded by v0.3.9)

Chrome extension, beta. Real-time British Sign Language overlay for any page.

If you are already on v0.3.7, you do not need to update

This is a housekeeping release. Comparing this build against v0.3.7 file by
file, 208 of the 209 files are byte-identical. The one change is a metadata
file that nothing reads at runtime, so the extension behaves exactly as v0.3.7
did. Updating is harmless, but it will not change anything you can see.

Install

1. Download signlytic-extension.zip below and unzip it.
2. Open chrome://extensions, turn on Developer mode (top right).
3. Click Load unpacked and select the unzipped folder.

What changed in 0.3.8

data/signs/index.json carried metadata that was wrong in every field. It
claimed zero bundled signs against 192 real ones, and its cdnBase pointed at
a raw GitHub path that is not published and returned 404. Nothing reads the
file, so this was a misleading signpost rather than a fault, but it now
reports the real figures and the endpoint the overlay actually uses.

Confirmed in this release, unchanged since 0.3.7

The microphone restart limiter was exercised against a real abort storm in a
browser, rather than only reasoned about. On repeated aborts it backs off at
500, 1000, 1500 and 2000 ms, stops after five attempts, reports "Speech
recognition keeps aborting", and leaves no pending timer behind. A successful
result clears the counter, so a burst of transient aborts does not disable the
microphone for the rest of the session. Denied microphone permission is
reported once and never retried.

The 3D avatar is fetched through the Signlytic website at runtime rather than
from a file attached to a release.

Avatar assets

The 3D character rig is built on third-party assets licensed for use in this
project but not for redistribution. They are not attached to releases and
not in the source tree. The 2D skeleton renderer needs no model and works
offline.
