Comparative Analysis of 3D Steering Tasks

This research article presents a comparative analysis of two 3D steering tasks, the Ring-and-Wire and Ball-and-Tunnel tasks, within the context of Human-Computer Interaction (HCI). The study aims to investigate the performance differences between these tasks through a within-subjects user study involving 18 participants. The findings indicate that the Ring-and-Wire task significantly outperformed the Ball-and-Tunnel task, showing lower task completion time, higher throughput, and faster average speed. Participants also reported a preference for the Ring-and-Wire task and experienced a lower workload. The study highlights the visual ambiguities present in the Ball-and-Tunnel task, particularly near the tunnel's rear surface, which complicates spatial perception. The authors recommend careful selection of 3D steering tasks for future experiments, as the two tasks are not interchangeable. This work contributes to the understanding of steering behaviors in immersive environments and provides practical implications for the design of XR applications and steering law studies.
