1. An object identification device combined with a millimeter-wave passive image system and global positioning system (GPS) for the blind, comprising:
- a millimeter-wave passive image wireless circuit (31) that consists of a patch antenna array, a low-noise amplifier and a phase shifter required for the millimeter image system to transmit/receive the millimeter-wave for the detection of millimeter-wave image signals;
a control unit that consists of an array antenna beam forming unit (321) for the beam forming of the millimeter-wave, a signal process unit (322) to analyze millimeter wave images, a GPS antenna (35) to receive position signals from a satellite and a GPS control unit (322) to control signals received from the GPS antenna;
an operation unit (33) that consists of an object identification unit (331) and a position navigation unit (332) to constitute the information about the ambient situation by using signal-processed data; and
an audio process unit (34) that consists of a voice process unit (341) for voice transformation using the millimeter image information and position information and a audio generation unit (342) to generate the transformed voice.

Abstract
This invention relates to an object identification device, for the blind, that identifies objects such as walls and cars by detecting the ambient environment through a 94-GHz millimeter-wave image system mounted on the eyeglass and inform the situation to the user by transforming the identified signals to the voice or sound.
This invention is designed to not only help the blind in walking but also provide the function to find the person who has a device realizing this invention.
