Improved Redirection with Distractors: A Large-Scale-Real-Walking Locomotion Interface and its Effect on Navigation...

Area of Science:

• Human-Computer Interaction
• Virtual Reality
• Navigation Systems

Background:

• Virtual environment (VE) navigation presents challenges compared to real-world mobility.
• Existing locomotion interfaces often require predefined paths or are limited by physical tracking space.
• Effective navigation is crucial for immersive and functional VE experiences.

Purpose of the Study:

• To introduce and evaluate a novel locomotion interface, Improved Redirection with Distractors (IRD).
• To compare the navigational performance of IRD against the established 'really walking' interface.
• To determine if IRD enables effective navigation in virtual environments exceeding physical tracking boundaries.

Main Methods:

• Development of the Improved Redirection with Distractors (IRD) locomotion interface.
• User study design to measure navigational ability in virtual environments.
• Comparative analysis of user performance between IRD and 'really walking' conditions.

Main Results:

• Users employing IRD successfully navigated virtual environments larger than the tracked space.
• IRD facilitated target pointing and map completion tasks comparable to 'really walking'.
• No significant difference in navigational ability was found between IRD and 'really walking' users.

Conclusions:

• Improved Redirection with Distractors (IRD) is a viable interface for large-scale VE navigation.
• IRD overcomes limitations of tracked space without compromising user navigational performance.
• This technology enhances the potential for expansive and interactive virtual experiences.
