Abstract

A device and related method are provided for assisting visually impaired persons obtain verbal information from consumer product bar codes. The devices includes a scanner unit, a processing unit, a power unit and a voice synthesizer. The method involves the person scanning the bar code of the product with the scanner unit to provide a first signal which is communicated to the processing unit for locating, retrieving and outputting product information corresponding to the bar code in a form for the voice synthesizer to generate a verbal output to convey the information to the person. The bar code may be raised to assist the visually impaired person in locating the exact location of the bar code to facilitate scanning thereof. The device and the method provide the visually impaired person with a level of information that about the product that is not normally obtained without the assistance of another person.

Claims

1. A device for providing visually impaired persons with verbal output of bar coded consumer product information on a consumer product, said device comprising:

(a) a scanner unit for providing a first signal in response to bar code information on a consumer product scanned by said scanner unit,

(b) a computer processing unit connected to said scanner unit for receiving said first signal, locating consumer product information corresponding to said bar code, and generating a second signal,

(c) a voice synthesizer connected to said computer processing unit to receive said second signal, said voice synthesizer being for general a verbal output of said consumer product information containing spoken language information corresponding to said bar code.

2. The device of claim 1 wherein said scanner unit is carried by a ring structure suitable for being worn on a persons finger.

3. The device of claim 1 wherein said computer processing unit and said voice synthesizer are carried on a belt suitable for being worn by a person.

4. The device of claim 2 wherein said ring has a tone generator attached thereto for generating a first tone upon a successful scanning of the bar code and for generating a second tone upon unsuccessful scanning of the bar code.

5. A system for assisting a visually impaired person in obtaining aural product information about a consumer product, said system comprising:

(a) a consumer product having a container, said container having a bar code thereon,

(b) a scanner unit for scanning said bar code and providing a first signal in response to bar code information scanned by said scanner unit,

(c) computer processing unit connected to said scanner unit for receiving said first signal, locating consumer product information corresponding to said scanned bar code, and generating a second signal, and

(d) a voice synthesizer connected to said computer processing unit to receive said second signal, said voice synthesizer being for general an audible output containing spoken language product information corresponding to said bar code.

6. The system of claim 5 wherein said bar code is in the form of raised print on a surface of said container, said print having an elevation of between 0.05 mil and 2 mil above said surface.

7. The system of claim 5 wherein said scanning unit is carried on a ring structure and said voice synthesizer and said computer processing unit are carried on a belt.

8. A method for assisting the visually impaired obtain consumer product information from a bar code on a consumer product, said method comprising:

(a) providing a device comprising (i) a scanner unit for providing a first signal in response to bar code information scanned by said scanner unit, (ii) a computer processing unit connected to said scanner unit for receiving said first signal, locating consumer product information corresponding to said bar code, and generating a second signal, and (iii) a voice synthesizer connected to said computer processing unit to receive said second signal, said voice synthesizer being for generating a verbal output containing spoken language information corresponding to said bar code,

(b) scanning a bar code from a consumer product with said scanning unit,

(c) listening to verbal output of said product information from said voice synthesizer.

9. The method of claim 8, further comprising providing an electronic storage element containing product information or other relevant data corresponding to said bar code.

10. The method of claim 8, wherein said device comprise a ring for carrying said scanner unit, and comprises a belt for carrying said computer processing unit and said voice synthesizer.
