Scribble Your Way Through Traffic

Abstract

Scribble is a haptic Human Machine Interface (HMI) that utilizes a drawing interaction to steer a semi-autonomous vehicle. The interface uses a display and a haptic pointing device that enables the driver to draw a path which represents the vehicle's future trajectory. The objective of Scribble is to blur the lines between who is in control and proposes a more 'muddy' form of interaction where higher decision making is performed by the human operator, whilst the machine manages more mundane driving tasks such as lane keeping and managing speed. We present a fully interactive desktop-based demo that includes a 3D simulation environment for highway driving. The interface has been tested in an elaborate simulation study in collaboration with the Mercedes-Benz Advanced Digital Design team at Daimler AG, Sindelfingen, Germany. The contents of this document describe: the Scribble concept, system setup, demo setup, and contribution.
