HEARING DEVICE PROVIDING SPOKEN INFORMATION ON SELECTED POINTS OF INTEREST
First Claim
1. A navigation system comprising:
- a hearing device configured to be head worn and having loudspeakers for emission of sound towards ears of a user, and accommodating an inertial measurement unit 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 a geographical position of the system;
a sound generator connected for outputting audio signals to the loudspeakers; and
a processor configured for;
selecting a POI in a forward looking direction of the user based on the determined head yaw, andcontrolling the sound generator to output the audio signals that represent spoken information on the selected POI.
