Point & Portal: A New Action at a Distance Technique For Virtual Reality

This paper introduces Point & Portal, a novel Virtual Reality (VR) interaction technique, inspired by Point & Teleport. This new technique enables users to configure portals using pointing actions, and supports seamless action at a distance and navigation without requiring line of sight. By supporting multiple portals, Point & Portalenables users to create dynamic portal configurations to manage multiple remote tasks. Additionally, this paper introduces Relative Portal Positioning for reliable portal interactions, and the concept of maintaining Level Portals. In a comparative user study, Point & Portal demonstrated significant advantages over the traditional Point & Teleport technique to bring interaction devices within-arm's reach. In the presence of obstacles, Point & Portal exhibited faster speed, lower cognitive load and was preferred by participants. Overall, participants required less physical movement, pointing actions, and reported higher involvement and "good" usability.
