A design Project with the Fire Brigade as the targeted user group. This system made the user aware of the location of their teammates using people’s sound localization ability. The system played a non intrusive repetitive sound and tweaked the left right balance based upon the location of a colleague relative to the user. This gives Firefighters an inherent feel for where their colleagues are in chaotic situations with poor visibility. This project was carried out in the Seamless Interaction Design squad in the Industrial faculty of the Eindhoven University of Technology.
