Apparatus for Supporting The Blind of Using a Wireless RFID Gloves}

The present invention relates to a device for assisting the visually impaired by using a wireless RFID (Radio Frequency Identification) glove, and receives the information about the attached object from the RFID tag by using a wireless RFID glove, and converts it into a voice signal and outputs the radio signal. Radio Frequency Identification) The present invention relates to a visually impaired assistive device using gloves.

Although the number of visually impaired people is more than 200,000 nationwide, the interests of the visually impaired are not so great, and the development of practical devices to improve the quality of life of the visually impaired is insufficient.

For example, when a blind person eats in a restaurant, a helper first guides the blind person to sit on a chair, which should be pulled toward the body so that the blind person can grab the head of the chair.

In addition, the hand of the visually impaired person should be placed on the table where the cutlery is placed, and the type and location of the food should be shown in a clockwise direction to see what food is placed on the table, and the chopsticks should be used to help identify the location of the dishes. .

At this time, the act of excessively interfere with the helper eating or picking food may displease the visually impaired.

In this case, not only the visually impaired but also the helper can feel uncomfortable, and it is not easy to act as a helper at every meal.

In this example, the inconvenience of the visually impaired people to eat, but the visually impaired people experience a number of other inconveniences, for example, when the visually impaired to take medicine, there is a way to properly check the medicine bottle You will be at risk of getting the wrong medication.

In general, the visually impaired person first recognizes the place where the bottle is placed through the helper and finds the corresponding bottle, but if the bottle is accidentally distracted, there is no way to identify the bottle. There is discomfort that must be received.

In addition, you can not find the products you want in the grocery store or shops, but you must get help from the clerk, but it is not easy to buy the goods with the help of the clerk.

It is an object of the present invention to provide a visually impaired assist device using a wireless RFID glove that allows the user to visually check information on a glove and an adjacent object to which an RFID tag is attached through a glove worn by a visually impaired person.

Like the first wireless communication module 230, the second wireless communication module 310 is selected from among Bluetooth, Wireless Local Area Network, Ultra Wide Band, UWB, and Zigbee. Use any short-range wireless communication means.

The memory 320 stores food content information received by the second wireless communication module 310.

The voice converter 330 converts food content information stored in the memory 320 into a voice signal (Text To Speech: TTS).

That is, the voice conversion unit 330 analyzes the grammatical structure of the food content information and then generates a rhyme like a human reading based on the analyzed grammatical structure, and stores the voice DB according to the generated rhyme. The food content information is converted into a speech signal by collecting the basic units of).

The speaker 340 outputs the voice signal converted by the voice converter 330 to the outside so that the visually impaired person can check the food contents.

The controller 350 controls each component. First, the controller 350 controls the second wireless communication module 310 to receive food content information from the first wireless communication module 230 and stores the received food content information in a memory. Save to 320.

The controller 350 controls the voice converter 330 to convert food content information stored in the memory 320 into a voice signal, and controls the speaker 340 to output the converted voice signal to the outside.

Here, the wireless RFID glove 200 and the voice conversion device 300 are implemented as separate devices, and the food content information read from the wireless RFID glove 200 is transferred to the voice conversion device 300 to convert the voice conversion device 300. Although it is configured to output after converting to a voice signal in the wireless RFID gloves 200 may be implemented by integrating the voice conversion device 300 in the unit. This will be described with reference to FIG. 3.

Figure 3 is a block diagram showing the configuration of another embodiment of the visual aid device using the wireless RFID gloves of the present invention.

Referring to FIG. 3, the apparatus for assisting the visually impaired using the wireless RFID glove of the present invention includes an RFID antenna 410, an RFID reader 420, a memory 430, a voice converter 440, a speaker 450, and a power supply unit. 460, the control unit 470.

 The RFID antenna 410 transmits an interrogation signal to an RFID tag (not shown) when an RFID tag (not shown) attached to each food container is located in a recognition area, and from the RFID tag (not shown). Receive the information stored in the tag chip.

The RFID reader 420 reads the information received by the RFID antenna 410 and checks the food contents contained in the food container to which the RFID tag (not shown) is attached.

The memory 430 stores food content information read by the RFID reader 420.

The voice converter 440 converts food content information stored in the memory 430 into a voice signal (Text To Speech: TTS).

The speaker 450 outputs the voice signal converted by the voice converter 440 to the outside so that the visually impaired person can check the food contents.

The power supply unit 460 supplies power to each of the components. As the power supply unit 460, a small battery such as a cadmium battery is preferably used, but various other types of batteries may be used.

The control unit 470 controls each component. First, when the RFID tag (not shown) is located in the recognition area, the controller 470 sends a question signal and receives information stored in the tag chip of the RFID tag (not shown) in response thereto. The antenna 410 is controlled, and the RFID reader 420 is controlled to read the information received by the RFID antenna 410 to check the food contents.
