Content Transfer Across Multiple Screens with Combined Eye-Gaze and Touch Interaction -- A Replication Study

TL;DR

This replication study confirms that combined gaze and touch input generally outperforms touch-only input for multi-screen content transfer in VR, with some variations likely due to user experience differences.

Contribution

The study replicates previous findings on multi-screen VR content transfer techniques, highlighting the robustness of combined gaze and touch interaction benefits.

Findings

Combined gaze and touch improves task completion time

Replication confirms usability benefits of combined input

Simulator sickness results vary with user experience

Abstract

In this paper, we describe the results of replicating one of our studies from two years ago which compares two techniques for transferring content across multiple screens in VR. Results from the previous study have shown that a combined gaze and touch input can outperform a bimanual touch-only input in terms of task completion time, simulator sickness, task load and usability. Except for the simulator sickness, these findings could be validated by the replication. The difference with regards to simulator sickness and variations in absolute scores of the other measures could be explained by a different set of user with less VR experience.
