Abstract
Received 14 December 2015; received in revised form 30 January 2016; accepted 1 February 2016ABSTRACT Traditional tactile controls that include push buttons and rotary switches may cause significantvisual and biomechanical distractions if they are located away from the driver’s line of sightand hand position, for example, on the central console. Gestural controls, as an alternative totraditional controls, are natural and can reduce visual distractions; however, their types and num-bers are limited and have no feedback. To overcome the problems, a driver interface combininggestures and visual feedback with a head-up display has been proposed recently. In this paper,we investigated the effect of this type of interface in terms of driving performance measures.Human-in-the-loop experiments were conducted using a driving simulator with the traditionaltactile and the new gesture-based interfaces. The experimental results showed that the new inter-face caused less visual distractions, better gap control between ego and target vehicles, and bet-ter recognition of road conditions comparing to the traditional one.Key Words:Driver distraction, Gesture interface, Head-up display, Human-machine interaction,In-vehicle system
