Poster: Comparing vibro-tactile feedback modes for collision proximity feedback in USAR virtual robot teleoperation

Although multi-sensorial interfaces have been shown to improve user experience in different settings in Virtual Reality, these interfaces are not yet fully explored in urban search-and-rescue robot teleoperation. This paper presents a study on the performance effects of adding different types of vibro-tactile collision proximity feedback to a virtual robot´s interface during a search task in a virtual environment. Results indicate that the addition of vibro-tactile feedback causes positive performance effects, especially for the intensity variation mode. Nevertheless, it also has a comfort impact for prolonged use.
