Going, Going, Gone: Exploring Intention Communication for Multi-User Locomotion in Virtual Reality

Going, Going, Gone: Exploring Intention Communication for Multi-User Locomotion in Virtual Reality Julian Rasch, Vladislav Dmitrievic Rusakov, Martin Schmitz, Florian Müller CHI 2023: The ACM CHI Conference on Human Factors in Computing Systems Session: VR/AR/XR Play Experiences Exploring virtual worlds together with others adds a social component to the Virtual Reality (VR) experience that increases connectedness. In the physical world, joint locomotion comes naturally through implicit intention communication and subsequent adjustments of the movement patterns. In VR, however, discrete locomotion techniques such as point&teleport come without prior intention communication, hampering the collective experience. Related work proposes fixed groups, with a single person controlling the group movement, resulting in the loss of individual movement capabilities. To close the gap and mediate between these two extremes, we introduce three intention communication methods and explore them with two baseline methods. We contribute the results of a controlled experiment (n=20) investigating these methods from the perspective of a leader and a follower in a dyadic locomotion task. Our results suggest shared visualizations support the understanding of movement intentions, increasing the group feeling while maintaining individual freedom of movement.
