SOUND DESIGN FOR DEMONSTRATOR

Sound Design for Demonstrator is a collaborative project between RISE Interactive (formerly called Interactive Institute) and Scania CV AB. The project aims to develop information sounds to be used in a demonstrator for future heavy trucks in order to increase traffic safety. The work has focused especially on the design of an auditory display to assist drivers in lane changing situations. Several research studies have been carried out as part of the user-centered design process. These studies have been conducted during both simulated and real-world driving, and have evaluated both warning efficiency and driver acceptance.

The resulting auditory display has a novel design, and makes use of intuitive 3D sound combined with subtle manipulations of the vehicles turn indicator signal. The display have has proven to have high acceptance among commercial drivers and is to be implemented in the demonstrator as part of the new innovative HMI.

Moreover, RISE Interactive are conducting research to explore new possibilities to inform drivers using sound. These examinations, which are funded by Swedish ICT, form an additional scientific complement to the development process conducted together with Scania CV AB.

Research on graded warnings

The auditory warning signals below were used in the study presented in the reseach paper ”Graded auditory warnings during in-vehicle use: Using sound to guide drivers without additional noise”. The paper is accepted for publication at the conference Automotive User Interfaces and Interactive Vehicular Applications 2012, October 17-19 2012. 

The study explored the usefulness of three alternative strategies to notify drivers in early stages of a threatening situation using sound: 1. panning the radio sound from the driver’s position (equal sound level in both ears) to one side; 2. reducing the sound level of the radio; and 3. a mild auditory warning signal (i.e., an added sound). In all three conditions the early warnings are followed by a late warning (intrusive sound), if the drivers don’t respond to them. Below, you can download and listen to the mild warning sound and the late warning sound used in the experiment.
