Abstract
The present invention is a locator device for the visually impaired including a transmitter and a dual sensing system having a receiver with earphones which are attached to opposite sides of a unit worn on the user's head. The sensing system is capable of determining a direction and distance of the signal, and capable of producing first and second audible notifiers in each of the earphones. The notifier produced in each earphone is different and is associated with the direction and distance of the transmitted signal. When the notifier produced in each earphone is the same, the user is directly in front of the desired object to be located.
