User Requirements for Remote Teleoperation-based Interfaces

Abstract

Despite the rapid progress of Autonomous Vehicle (AV) technology, remote human situational assessment continues to be required. Herewith, remote operation is introducing several challenges, as limited perception and difficulty in maintaining Situation Awareness (SA). In this regard, this research provides first-hand SA requirements for remote teleoperation-based interfaces. Complementary to a previous literature review on requirements for Human-Machine Interface for unmanned systems, we conducted two (N = 18, N = 10) user studies. To ascertain the views of the users, we employed two methodologies, in-depth interviews, and traditional statistical analysis to find out specific preferences. We collected a total of 80 statements that we could cluster over 12 categories, presenting a comprehensive overview of SA user requirements. The research is envisioned to be used by others as a tool to help the development of AV teleoperation-based interfaces.
