The thesis cooperating with Tec-Innovation investigates potential approaches to acoustic information transmission, being used to support the locomotion of blind and visually impaired people, with regard to creating substantial communication between product and user, to reduce the risk of cognitive overload resulting in a higher acceptance of the users.
The developed system is developed based on the findings of co-design and resulted in a framework setup and guidelines for future development. The system mainly consists of active and passive acoustic signals, where active signals influence the walking behavior (Abnormal and emergency: hazards that can cause injury and guidance) and passive signals (Notice: objects of interest) are used to provide the user with more specific information about the surrounding. The acoustic feedback was conducted with auditory icons and earcons.
