Abstract

This paper investigates how perceivable haptic feedback patterns are using an actuated surface on a steering wheel. Six solenoids were embedded along the surface of the wheel, creating three bumps under each palm. The solenoids can be used to create a range of different tactile patterns. As a result of the design recommendation by Gallace et al. [Gallace2006a] maximally four of the six solenoids were actuated simultaneously, resulting in 57 patterns to test. A simulated driving study was conducted to investigate (1) the optimal number of actuated solenoids and (2) the most perceivable haptic patterns. A relationship between number of actuated solenoids and pattern identification rate was established. Perception accuracy drops above three active solenoids. Haptic patterns mirrored symmetrically on both hands were perceived more accurately. Practical applications for displaying tactile messages on the steering wheel are e.g. dead angles, upcoming road conditions, navigation information (i.e. conveying information discretely to the driver).
