Direction guidance providing device for e.g. visually impaired person, has microprocessor that provides output signal calculated from direction and position information of user, and obstacle position information, to user earphone

摘要

The device has a microprocessor to receive a signal indicating position information of a user from a GPS module and direction information of the user from a compass. Ultrasonic sensors (3) sense obstacles and their positions. The microprocessor provides an output signal calculated from direction and position information of a user, and position information of obstacles using default and steady algorithms, to the user earphone.
