Purpose and goal
The project´s objective was to examine the potential of sound as a medium for communication during unsupervised AD to support trust, comfort, safe user interaction, acceptance and enjoyment, focused on the following applications. - Using sound to reduce motion sickness - Using sound to increase trust and acceptance - Using sound to improve usability, understanding and learning - Aesthetically pleasing, mood-inducing, enjoyable sonification The project hypothesized that a continuous sound design is more effective compared to traditional chimes, within all application areas.
Expected results and effects
The main is finding that our sonic interaction paradigm can reduce motion sickness and increase trust in AD cars. This solution can potentially become a new customer function that is both effective, acceptable and desirable by users. The project has produced five scientific publications, a functional demonstrator vehicle for sonic interaction, a set of design methods, a related design framework, and initiated a collaboration between research, the gaming business and the automotive business. We have presented the results at a public seminar and by a project movie.
Planned approach and implementation
Evaluation 0 tested the general methodologies and initial framework ideas using recorded video material together with sound design concepts. Evaluation 1 tested the hypothesis that an auditory display could increase trust while still being perceived as acceptable and preferred over having no sound. VR was used for this experiment. Evaluation 2 tested whether anticipatory sound informing participants of upcoming maneuvers could reduce motion sickness. The experiment was carried out in a real vehicle on a test track. The third evaluation was an iterative test, based on Evaluation 1.
