Virtual reality (VR) has the potential to fully immerse users in digital worlds. But how can we integrate natural walking into VR when the virtual environment is much larger than the physical space available? This challenge, known as the "locomotion problem," has led to the development of redirected walking (RDW) controllers. While offering solutions, this technology also comes with challenges. PhD research by Charlotte Croucher combines innovative ideas to enhance the user experience.
In many VR applications, the virtual world far exceeds the size of the physical space. RDW controllers address this by subtly guiding users, allowing them to move safely without collisions in the real world. However, there are limitations, such as simulator sickness, increased mental workload, and computational inefficiencies that can detract from the experience.
A new approach
PhD candidate Charlotte Croucher has developed the LoCoMoTe framework and dashboard to bridge machine learning-driven simulations and live-user experiments in redirected walking (RDW) research. This innovative tool fosters collaboration and open science, helping researchers design simulations that account for human movement behaviors like stumbling.
The role of virtual environment design
The design of the virtual world itself plays a key role in influencing walking behavior. Using interactive cues, such as prominent objects, has proven to be an effective way to subtly guide users in a desired direction.
Experiments also showed that these cues not only work effectively but also enhance the overall user experience. Strategically placed objects increased user interest and enjoyment without compromising immersion or autonomy.
The future of natural movement in VR
Charlotte Croucher’s research highlights the importance of smart virtual environment design and offers new insights for improving RDW controllers. The combination of simulations and live testing provides a solid foundation for further innovation, bringing us closer to seamless and natural movement in VR.
