Dataset Converter

To manipulate and convert datasets to our format to use with Monitor Sample of https://github.com/nokiatech/omaf. There are two types of converters;

• The Hamilton Quaternion to Euler Angles
• Gaze and Head motion dataset to Euler Angles and separate gaze data

From the unit Hamilton Quaternion to Euler Angles Converter

Convert Head Motions from the Hamilton Quaternion to Euler Angles. 360-Degree Video Head Movement Dataset: https://dl.acm.org/do/10.1145/3193701

Usage

Place results folder to the project root. The output will be written to heads folder. Format;

• quaternion-to-euler.py
• results
  • uid_id
    • test_id
      • VideoName
        • HeadMotionLogs.txt
• heads
  • VideoName_uid

Output

There are head motions for different videos. Format: videoName_userID Example: diving_0, diving_1, etc

Note that some users did not test some videos. So, some head motion files can be missing. For instance; rhino_0, rhino_3, rhino_5, rhino_8, ... rhino_2, rhino_4, rhino_5, rhino_6, rhino_7, ... are missing

EH Task Dataset Converter

The data is 8 columns: timestamp, frame, head_x, heady, gaze_x_unit, gaze_y_unit, gaze_x, gaze_y. The script splits the head and gaze data to separate files. EHTask: Recognizing User Tasks from Eye and Head Movements in Immersive Virtual Reality: https://ieeexplore.ieee.org/document/9664291

Usage

Place RawData folder to the project root. The output will be written to eh_heads, gaze_unit, gaze_coor folders. Format;

• eh-dataset.py
• RawData
  • User_X_Video_Y_Task_Z.txt
• eh_heads
  • User_X_Video_Y_Task_Z
• gaze
  • unit
    • User_X_Video_Y_Task_Z
  • coor
    • User_X_Video_Y_Task_Z
