Convey situation awareness in conditionally automated driving with a haptic seat

Abstract

Conditionally automated driving is rapidly evolving and one of its major issues is the reduction of the driver's attention to her/his environment. After a brief study of interactions increasing situation awareness, and more specifically haptic interactions, this paper proposes the use of vibrations in the seat. Vibrations, with the variation of their location, frequency and amplitude, allow to transmit to the driver various information such as the position of obstacles around her/his vehicle and the state of deterioration of track markings. The results of a first exploratory test are promising on the use of haptic interactions and they pave the way for future experiments.
