Abstract: The rapid development of Driver Assistance System (DAS) provides drivers with radically enhanced information and functionality. The nature of the current DAS requires a complex human-machine interaction which is distracting and many increase the risk of road accidents. The interaction between the driver and DAS should aid the driving process without interfering with safety and ease the vehicle operation. Speech and audiobased interaction mechanisms employed are not sufficiently robust to deal with the noise present in the interior environment of the vehicle. Furthermore, too many types of driving-related information may burden the driver cognitively. Therefore, the thesis is aimed at solving the interaction issues between the driver and DAS. In order to solve the stated research issues, previous research works need to be studied. It includes the study of various DAS (components and functionalities) (2) cognitive workload measurement techniques and evaluation methods (3) interaction methodology between the driver and DAS (4) auditory design principles, focusing on earcons/auditory icons. The proposed methodology is tested in various experiments to ensure its validity and integrity. These experiments are divided into sections which test: (1) the earcons/auditory icon design principles (pattern recognition and identification) (2) real-time driving simulations, which focus on several driving conditions and situations. The outcome will be an interaction mechanism which can be integrated with any existing DAS that manages the interaction process between the DAS and the driver. The novel contributions of this thesis consider all the components of the Driver Assistance System as a single entity instead of focusing on a certain device or component only. It is because these components will compete for the driver’s attention and requires the driver to response. It also outlines an environment for browsing audio-based information that provides a spatial interface for temporal navigation of audio data, taking advantage of the human ability of simultaneous listening and memory of spatial location. In this approach, the representation of any incoming driving-related information to the driver is based on the cognitive load and availability of the driver itself. Besides that, hybrid earcon/auditory icon design principles suitable for such purpose are developed. These interfaces are investigated in driving simulators in-order to test their durability and robustness. This will ensure the driving-related information from the invehicle telematic system is delivered to the driver without affecting the overall driving process.
