• supportsORT recovered reflected on-screen text from eyeglasses in video calls: The authors' Zoom experiments used a 1080p webcam and found that 25-30 mm text retained over 80% recognition accuracy in most tested environments. Recognition fell sharply below 20 mm; 15 mm text was almost never recognized outside the bright-room, white-screen condition. These results concern prepared reflection tests, not arbitrary screen text.

• supportsORT recovered reflected on-screen text from eyeglasses in video calls: ORT uses preprocessing and scene-text detection/recognition to extract text reflected in eyeglasses from video-conferencing imagery.
