GUD WIP: Gait-Understanding-Driven Walking-In-Place
Proceedings. IEEE Virtual Reality Conference
|January 27, 2015
Summary
We developed a Gait-Understanding-Driven Walking-In-Place (GUD WIP) model for virtual locomotion. GUD WIP generates more realistic and responsive virtual walking speeds compared to current systems.
Area of Science:
- Human-Computer Interaction
- Virtual Reality
- Biomechanics
Background:
- Exploring large virtual worlds requires effective locomotion techniques.
- Current Walking-In-Place (WIP) systems often lack realistic speed control and responsiveness.
- Bridging the gap between real-world walking and virtual movement is crucial for immersion.
Purpose of the Study:
- To introduce a novel model for generating virtual locomotion speeds from WIP inputs.
- To enhance realism and responsiveness in virtual walking by incorporating biomechanical principles.
- To compare the proposed model against existing WIP systems.
Main Methods:
- Developed the Gait-Understanding-Driven Walking-In-Place (GUD WIP) model based on gait principles.
- Implemented the GUD WIP model to generate virtual locomotion speeds from user's walking-in-place input.
- Conducted a user study comparing GUD WIP, Real Walking, and Low-Latency, Continuous-Motion (LLCM) WIP.
Main Results:
- GUD WIP speeds more closely match real walking speeds and respond better to step frequency variations.
- GUD WIP exhibits significantly less within-step fluctuation compared to LLCM-WIP.
- User study confirmed GUD WIP's consistent speed response to step frequency, unlike LLCM-WIP.
Conclusions:
- The GUD WIP model offers a more biomechanically accurate and responsive virtual locomotion experience.
- GUD WIP provides smoother and more consistent virtual walking speeds, improving upon current WIP technologies.
- This approach enhances user interaction and immersion in large-scale virtual environments.
