Walking in a cube: novel metaphors for safely navigating large virtual environments in restricted real workspaces

Area of Science:

• Virtual Reality (VR) and Human-Computer Interaction (HCI)
• Immersive Technologies and User Experience

Background:

• Immersive virtual reality (VR) systems offer realistic experiences but face locomotion limitations due to restricted physical spaces.
• Current VR locomotion methods often restrict user movement, hindering natural interaction and increasing the risk of boundary collisions.

Purpose of the Study:

• To develop and evaluate novel VR locomotion techniques addressing safety, increased physical walking, and enjoyable interaction.
• To compare the effectiveness of new techniques against traditional controller-based locomotion.

Main Methods:

• Proposed three novel locomotion techniques: Virtual Companion, extended Magic Barrier Tape, and Constrained Wand.
• Conducted a user study involving travel-to-target and path-following tasks to evaluate the techniques.
• Collected data on user safety, physical walking engagement, and subjective experience (fun, ecological interaction).

Main Results:

• Traditional controller interfaces with novel warning techniques may be best for speed and accuracy.
• Extended Magic Barrier Tape and Constrained Wand techniques promote greater physical walking.
• The Virtual Companion paradigm scored highest on fun and ecological interaction criteria.

Conclusions:

• Novel locomotion techniques can effectively enhance VR experiences by balancing safety, physical activity, and user enjoyment.
• The choice of locomotion technique should be tailored to specific user goals, whether prioritizing speed, physical engagement, or immersive interaction.
