Contribution of vibrational modalities for navigation in virtual environments

subject

description

The virtual environment navigation may induces the simulator sickness depending on conditions and user’s profile. The potential virtual reality multimodality may provide solutions to these problems while improving the sense of presence. In this context, the objective of this research is to determine what is the impact of vibrational modalities for navigation in virtual environments on the simulation.A taxonomy of navigation methods is proposed. It results in 4 types, specific egocentric, specific exocentric, abstract egocentric and abstract exocentric. First we simulate rumble strip vibrations during a driving simulation. The experimentation exposed that these vibrations make driver more aware about the environment and his driving safer. We also develop 3 vibratory modalities, proprioceptive vibrations, footstep vibrations and continuous vibrations. Experimentations show that vibrations help to reduce simulator sickness and to increase the sense of presence depending on the used navigation method in the simulation. Last we develop and evaluate 2 vibration languages for guidance, Pushing pattern and Compas pattern. The evaluation exposes that Compass pattern is better in guiding the user.
