Semi-autonomous driving is rapidly evolving and one of its major issues is the reduction of the driver's attention to his/her environment. After a brief study of current interactions increasing this situational awareness, and more particularly haptic interactions, this article proposes the use of vibrations in the seat. Vibrations, due to their location and variations in frequency and amplitude, make it possible to convey different information to the driver such as the position of obstacles around his/her vehicle as well as the state of deterioration of the road markings. The results of initial exploratory tests are promising on the use of haptic interactions. They make it possible to set up the design and procedure for future experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
