Measuring inferred gaze direction to support analysis of people in a meeting

作者：

Highlights：

• Robust capture of gaze direction based on a single depth-based sensor placed overhead.

• Achieved a head detection performance of 99.6% and a positive gaze detection of 97.3%.

• Detection of common fixation point from intersection of individual gazes.

• Supports analysis of the interaction of a group of participants.

• Validated on manually-measured ground truth data.
