Jarnail Chudge, with Microsoft UK, and Chancey take us on a journey where 3d audio could assist us in daily navigation. In concert with Guide Dogs UK, Jarnail provides an overview of the Cities unlocked program and a general description of their approach to aid existing mobility techniques. This fascinating interview contains Chancey s description of the convention demonstration, what cultural differences were observed between users on both sides of the Atlantic and concludes with some idea of what might be learned from the project s findings for practical use in a natural setting.
