Empirical Evaluation of Multi-Modal Touch Detection in Over-the-Shoulder Video Surveillance
An empirical evaluation of a multi-modal touch detector using MediaPipe, HSV skin filtering, motion differencing, and Canny edges finds low F1 scores on staged video and excessive false positives on real videos, concluding the approach does not enable reliable keystroke reconstruction outside contro
