Description

Smart cane and guidance system for blind people using the same {Guide device for blind people using electronic stick and smartphone}

The present invention relates to a smart wand and a guide system for the visually impaired using the same, and in more detail, a smart wand and a smart wand are configured to wirelessly communicate, and the smart wand has a GPS for providing the user's current location information and guides the same to the user. A smart wand and visually impaired persons configured to be detachable by separating the smart wand into a stick body and a head by installing guidance means such as vibration or voice to receive directions to the destination alone using only a smart wand. It relates to the guidance system.

In general, visually impaired people rely on blind dogs or walking sticks to recognize the braille blocks installed on the floor to overcome visual obstacles, thereby going out to the outdoors.

That is, when visually impaired people walk along a braille block guidance line made of a plurality of braille blocks, they walk by touching the edge component of each braille block several times with a cane or by recognizing it through the feeling of the sole of the foot.

However, it takes a lot of time for the visually impaired to walk by recognizing the braille block only with their senses through the cane or the sole of the foot, and there is a problem that stress is generated according to the movement situation due to the damage of the braille block .

Accordingly, recently, a device has been proposed that photographs the surroundings of a visually impaired person with a camera, analyzes the photographing information, and provides walking information corresponding to a braille block by voice.

However, the above-described walking information guidance system for the visually impaired is to provide only the walking direction by voice based on the braille block formed on the floor surface photographed by a camera. Since it does not provide information about the visually impaired, there is a little risk for the blind to walk freely.
