| Feature | F-Score | Leaders Mean (±SD) | Followers Mean (±SD) |
|---|---|---|---|
| Looking at | 1.800 | 0.36 ± 0.09 | 0.57 ± 0.13 |
| Looked at_Ratio | 1.700 | 2.43 ± 1.07 | 0.85 ± 0.53 |
| Looked at | 1.300 | 0.72 ± 0.18 | 0.43 ± 0.17 |
| Looked at_multiple | 1.300 | 0.28 ± 0.13 | 0.10 ± 0.08 |
| Mutual gaze | 0.780 | 0.41 ± 0.14 | 0.24 ± 0.12 |
| Mutual gaze_mutiple | 0.450 | 0.26 ± 0.14 | 0.15 ± 0.10 |
| Mutual gaze response time | 0.350 | 0.13 ± 0.06 | 0.19 ± 0.08 |
| Mutual gaze initiation | 0.085 | 0.27 ± 0.08 | 0.24 ± 0.07 |
Features are ranked based on F-scores, higher values indicating higher contribution to the classification. The unit of measurement for the means is the proportion of frames in which the visual behavior occurred (see Table 1).
