Diferences in cognitve load between virtual driving in VR and on regular screens

Sammanfattning: A interstep between a regular car and a fully self-driving car is a teleoperated car, where the driver controls the car remotely in situations that the self-driving AI isn't equipped to handle. The cognitive load of regular driving is known, and how long it's safe to drive without taking a rest, but it has not been that well explored when it comes to teleoperated driving. This paper examines which screen set-up would be preferable for the operator to use, comparing the cognitive load while using a driving simulator on a conventional computer screen and a head mounted display. The data that was able to be analyzed points to there not being any noticeable difference between the two in terms of cognitive load, but the participants noted the HMD has several advantages over the conventional screen. Despite this, the majority of the participants preferred the conventional screen due to cybersickness and discomfort from the HMD.
