*** General introduction ***
This dataset contains data collected during a Virtual Reality experiments at Delft University of Technology. The experiments took place 15 May 2024 until 2 June 2024. 
This dataset is being made public both to act as supplementary data for publications and in order for other researchers to use this data in their own work.

If someone wants to use the data, ensure to cite the corresponding author (A. van Beek) and the following publication:

*** Description of the data in this data set ***
The dataset is separated into three separated files: 'passingpoints_total', 'step_data' and 'traj_clean'. 
The first file represents the moments in time that participants passed on of the two counting lines. 
The second file records the moments in time that one of the feet of the pedestrians touches the floor during the real-life and virtual reality experiment.
The third file records the coordintates of the head of the participant during the VR experiments. 

The full description of the experiment can be found in the Publication. In essence, participants were asked to walk on a circuit in real-life, and in a virtual environment
while wearing a HMD. While wearing the HMD, the light color of the environment was changed multiple times to determine whether the participants movement dynamics would change.

Description of columns in data set 'passingpoints_total:
* 'personid': identifier for each unique participant.
* 'crosssection_id': Unique identifier for each cross-section at which the moment of passing was recorded.
* 'direction': movement direction of the individual.
* 'time_seconds': the timestamp, recorded in seconds since the start of the experiment.

Description of columns in data set 'step_data:
* 'personid': identifier for each unique participant.
* 'experiment_type': Identifier for each experiment. 0 = real-life experiment, 1 = VR experiment.
* 'leg_count': The count of the number of straight legs the participant has walked. Leg 1 is the first leg the participant is walking. 
* 'stepduration': Timeperiod between two consequtive feet touching the floor.
* 'steplength': Length in meters of 1 participant step.

Description of columns in data set 'traj_clean':
* 'personid': identifier for each unique participant.
* 'scenario': identifier for the VR scenario, in this case always scenario 7.
* 'timecode': time since start VR experiment in HH:MM:SS.FFFFFF
* 'time_seconds': time recorded in seconds since the start of the VR experiment (IS NOT the same time as time_seconds in passingpoint_total).
* 'X': X coordinate in meters.
* 'Y': Y coordinate in meters.
