Abstract

Autonomous vehicle (AV) technology has brought a shift in the traditional role of the driver. This paper applies a user-centred design approach to designing a new AV interior to better support drivers. Three empirical studies were conducted, involving a total of 92 drivers (with 44 in Study 1, 12 in Study 2, and 36 in Study 3) to explore user needs and requirements in an AV. In Study 1, safety and comfort, together with a variety of non-driving activities, were identified as the principal concerns about future autonomous vehicles. Based on these findings, Study 2 proposes a new rotatable seating position for AVs, with an in-vehicle information display to facilitate users' activities and situational awareness while driving. Study 3 consists of a series of laboratory simulator evaluation studies, and this indicated that drivers in the proposed design condition had better situational awareness in an AV when dealing with take-over situations. Such findings suggest the possibility of applying rear-facing seats in autonomous vehicles to support in-vehicle non-driving activities. Some specific implications of designs to enhance a driver's situational awareness have also been suggested.
