We propose to enhance utility of Advance Driver Assistance Systems (ADAS) with an interface that creates luminous signals able to be handled by peripheral vision while driving. The system, called Lighting Peripheral Display (LPD), consists of a box illuminated by LEDs whose light is reflected onto the windscreen. The shapes of the box are designed so that reflections can easily match the problems signaled by the ADAS. Surface, colors and movements are modulated to graduate urgency and to discriminate between the different assistance systems. A user test has been done on a driving simulator to compare a cluster with and without LPD. Both subjective and objective data (oculometry, vehicle parameters) were collected. They show that driving performance and comfort are enhanced by LPD. Reaction time is reduced for the most frequent warnings; perceived utility of ADAS is increased. However, driver's eyes tend to look at LPD instead of the cluster; peripheral vision utilization is thus not validated but, as ocular path is smaller with LPD, it helps the driver to keep his vision on the road.
