| # CMOSE: Comprehensive Multi-Modality Online Student Engagement Dataset with High-Quality Labels |
|
|
| ## Project page is [here](https://jasonwuchi.github.io/CMOSE/) |
|
|
|
|
| ## Video clip name |
| Each video clip is named as videoX_Y_personZ, which means it is the Yth clip of the Zth subject from coaching session X. |
|
|
| ## Openface |
| We extract the second level features from [OpenFace](https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation). The extracted files are stored under "secondfeature/videoX_Y_personZ.csv". These features include: |
|
|
| - **Gaze Direction and Angles** |
| - Three coordinates to describe the gaze direction of left and right eyes respectively |
| - Two scalars to describe the horizontal and vertical gaze angles |
|
|
| - **Head Position** |
| - Three coordinates to describe the location of the head relative to the camera |
|
|
| - **Head Rotation** |
| - Rotation of the head described with pitch, yaw, and roll |
|
|
| - **Facial Action Units (AUs)** |
| - Intensities of 17 AUs represented as scalars |
| - Presence of 18 AUs represented as scalars |
|
|
| ## I3D |
| We use the [I3D Repository](https://github.com/v-iashin/video_features) to extract the I3D vectors. One I3D vector is extracted for each clip. The features are stored in "final_data_1.json". |
|
|
| ## Acoustics |
| We use [ParselMouth](https://github.com/YannickJadoul/Parselmouth) to extract the acoustics features. They are stored in "label_results_w_audio_final.json". We also calculate the high level features such as the percentage of high/low volume, high/low pitch, and std of volume/pitch. These are stored in "new_bert_ac_dict.json". |
| |
| ## Narrations |
| We collect the narrations from the Live Transcript functions in Zoom. They are stored in "label_results_w_audio_final.json". We also extract the bert features from the narrations and store them in "new_bert_ac_dict.json". |
|
|
| ## Data split |
| Split information can be found in "final_data_1.json". Note that "split" should be one of "train", "unlabel", and "test". We use "unlabel" for validation purposes. |
