Evaluation of a Vibrotactile Device For Outdoor and Public Transport Pedestrian Navigation Using Virtual Reality

Abstract : It can be difficult to find your way in public transport, especially when the journey combines indoor and outdoor trans-portation. We designed an innovative vibrotactile device dedicated to guide a pedestrian in public transport. This multi-modal interface can be used to guide a pedestrian in unknown public transport. The device can be used by visually impaired person. The device has been tested during two main phases. The first step was to test the device using virtual reality while the second step test was to test the device in a real environment. This paper presents the first part of the evaluation of the device. We have developed a virtual reality scenario to assess the objective and subjective utility of the device. The results showed that the device could properly guide users. We also evaluated the usefulness of a warning vibration preceding a message. It was found that the vibration seems to introduce confusion to the pattern recognition by the user.
