Open data set for: Intermittent control and retinal optic flow when maintaining a curvilinear path

https://doi.org/10.5878/vjkp-z436
The data set contains the post-processed data used for the analysis of the paper. The post-processed data is derived from points of view rendered images (as seen by the research participants), their gazing behavior, and vehicular data when the research participants are driving in a double-lane S-shaped drive track on a texture-rich asphalt virtual reality. The post-processed data consists of ballistic control correction strength (acted on the steering wheel), retinal optic flow spatial angular mean, naive optic spatial angular mean, vehicular heading deviation, and vehicular lateral displacement. Statistical analysis data using correlation measures is also included. The data set also includes short demo videos showcasing the experimental trials as the research participants would have experienced, post-processing of visual data, and retinal optic flow. The raw data set containing some sensitive personal data may be requested through the closed data set catalog entry (2024-471).

Data format/​data structure:

Data collection Laboratory experiment

Mode of collection:

Laboratory experiment

Description of the mode of collection:

All devices are connected to a personal computer with computer graphics rendering capabilities, via the serial bus, and ethernet. All incoming data is serialized and harmonized within OpenDLV powered by libcluon. The graphics rendering pipeline is carried out through OpenVR with Vulkan API interfacing to OpenDLV. The vast majority of the raw data is serialized and saved within OpenDLV in rec-files. Graphics rendering data is saved via binary files to be post-rendered at a later point to unpack the data.

Instrument

Name:

HTC Vive Pro 1

Description of the instrument:

Virtual reality equipment consists of head-mounted displays and base stations. Measures head kinematics and provides visual image rendering to the wearer. Image of size 1440 x 1600 pixel resolution per eye at 90 Hertz with a 98-degree field of view. The head mount device connects directly to the graphics card of the rendering computer and serial-bus. The base stations connect wirelessly to the system.

Name:

HTC Vive Binocular Add-on (eye tracking system)

Description of the instrument:

HTC Vive Binocular Add-on from Pupil Labs, an eye-tracking system addon for HTC Vive 1. Provides gaze- and eye-modeling data. The device communicates via a serial bus, interfaced with their Pupil software.

Name:

SensoWheel (steering wheel)

Description of the instrument:

A steering wheel system from Sensodrive with force feedback capabilities with a mounted torque sensor. The system communicates via CAN-bus.

Name:

Logitech G27 pedals

Description of the instrument:

A pedal system, from Logitech G27 set, from Logitech repurposed for the experiment. The pedal actuators provide analog voltage levels.

Name:

LabJack T4

Description of the instrument:

A low-level measurement device handling analog to digital signal processing in this experiment. This is used to measure the pedal signal system from Logitech G27 and the torque from the SensoWheel.
