SignalRoom 0.1.0 Beta 1

SignalRoom 0.1.0 Beta 1

SignalRoom gives presenters a second-screen view of visible audience cues in
Zoom Gallery View. It separates highly engaged, following, confused, and
attention-drift signals and turns the room state into a glanceable presenter
response.

Included

• Local Windows inference using the frozen SignalRoom Live v20 model
• Validated gallery_person_relative_v1 presenter policy
• Selected primary_hand_1440_q82 compute profile
• Up to 49 participants rendered on one visible Zoom gallery page
• Local session timeline and summary
• Installer and portable package for 64-bit Windows 10 and Windows 11

Privacy

• No microphone access
• No retained meeting video
• No upload of meeting frames or reports to a SignalRoom cloud service
• No participant identity profiles
• Research recording and development controls are disabled

Evidence

On one frozen three-person Zoom holdout with recording-level phase labels, the
selected policy reached person-level macro-F1 0.751 and accuracy 0.778.
Room-level presenter-action macro-F1 was 0.851.

Across eight final paired replay trials, the selected compute profile preserved
presenter outputs exactly and reduced backend analysis time by a source-mean
11.41%, with a 95% bootstrap interval of 8.11% to 14.71%.

These results are local research evidence, not a universal classroom accuracy
claim.
