Abstract
Navigation systems are commonly used in our daily lives. Research has shown that spatial audio presents one opportunity for more effectively communicating to the driver the direction of the next manoeuvre. This thesis project proposes a new feature for the spatialisation of the audio cues triggered by a mobile navigation system by using a virtualised vector-based panning (VVBP) architecture for the encoding and decoding. The prototype developed during this thesis enables the spatialisation using headphones- or speakers-based systems. This study aims to promote a new sound experience to the user, which can be used to increase the safety and performance of driving. Based on an expert review and a user test, the application was tested on different scenarios. The participants selected during these sessions were part of HERE Technologies, which made possible to reach design experts who knew the current application provided by the company beforehand, making easier the comparison with the proposal. This selection could also present a limitation on the study since the users might have a personal bias for seeing new features in a product which have already worked on. Analysis of the results obtained during the testing session demonstrated high satisfaction with the feature by the users and a better understanding of their surroundings. Consequently, this indicates that spatial audio can improve the performance of driving by introducing a new source of information for positioning the next turn or obstacle. Further research is needed to identify other factors that could strengthen the effectiveness of the product.Description
