“…Hollerbach et al [5] reported a treadmill-based locomotion interface that used a mechanical tether to center users as they walked or ran on a larger treadmill. In addition to centering the user, the mechanical tether applied inertial forces to give the subject a natural feeling during acceleration and deceleration.…”

“…Locomotion interfaces that attempt to simulate natural walking have been reported previously, but they were expensive for practical implementation (usually because they embodied features not needed for the experiments, such as rapid tilt for rough terrain simulation, split-belt walking, and support for running speeds) [5], were unstable without subject training [6], or did not actually simulate walking [7]. Hollerbach et al [5] reported a treadmill-based locomotion interface that used a mechanical tether to center users as they walked or ran on a larger treadmill.…”

In this work we propose an extension of our laboratory evaluation framework [1] equipped with a virtual environment (VE). In order to simulate ecologically valid walking in the VE, we evaluate biomechanical processes in gait to control the speed of the treadmill that participants in the laboratory are walking on. Our approach allows predicting the actual speed while walking based on hip movement and additionally on step length. In order to validate our approach we present preliminary results from a study comparing different walking tasks in a VE.

“…These interfaces, despite the promising results, are not still in a commercial form, or in some cases (e.g., [6,8,19]) place demands that are impractical for many laboratories such as large space for the device and frequent, specialized maintenance with high costs.…”

Previous studies suggest significant differences between navigating virtual environments in a lifelike walking manner (i.e., using treadmills or walk-in-place techniques) and virtual navigation (i.e., flying while really standing). The latter option, which usually involves hand-centric devices (e.g., joysticks), is the most common in Virtual Reality-based studies, mostly due to low costs, less space and technology demands. However, recently, new interaction devices, originally conceived for videogames have become available offering interesting potentialities for research. This study aimed to explore the potentialities of the Nintendo Wii Balance Board as a navigation interface in a Virtual Environment presented in an immersive Virtual Reality system. Comparing participants' performance while engaged in a simulated emergency egress allows determining the adequacy of such alternative navigation interface on the basis of empirical results. Forty university students participated in this study. Results show that participants were more efficient when performing navigation tasks using the Joystick than with the Balance Board. However there were no significantly differences in the behavioral compliance with exit signs. Therefore, this study suggests that, at least for tasks similar to the studied, the Balance Board have good potentiality to be used as a navigation interface for Virtual Reality systems.
