A personal navigation system with a hearing device

A personal navigation system is disclosed, comprising a hearing device configured to be head worn and having loudspeakers for emission of sound towards the ears of a user and accommodating an inertial measurement unit positioned for determining head yaw, when the user wears the hearing device in its intended operational position on the user's head, a GPS unit for determining the geographical position of the user, a sound generator connected for outputting audio signals to the loudspeakers, a pair of filters with a Head-Related Transfer Function connected in parallel between the sound generator and the loudspeakers for generation of a binaural acoustic sound signal emitted towards the eardrums of the user and perceived by the user as coming from a sound source positioned in a direction corresponding to the respective Head-Related Transfer Function, and a processor configured for determining a direction towards a desired geographical destination with relation to the determined geographical position and head yaw of the user, controlling the sound generator to output audio signals, and selecting a Head-Related Transfer function for the pair of filters corresponding to the determined direction towards the desired geographical destination so that the user hears sound arriving from the determined direction.
