Abstract

Embodiments herein provide/acquire a document in electronic form (e.g., by receiving, copying, retrieving from storage, scanning combined with optical character recognition, etc.) and receive user input regarding visual impairment. In response to one or more levels of user visual impairment, embodiments herein automatically change (for example, immediately after scanning text) an appearance of the document, without requiring any user input, other than the visual impairment input. More specifically, when changing the appearance of the document, embodiments herein can increase the size of characters in the document, change the contrast or coloring of the text and/or background, and provide text-to-speech conversion of the document, thereby (in one embodiment) producing audio output of the text-to-speech conversion in coordination with a corresponding portion of the document being displayed. When changing the appearance of the document, embodiments herein also reformat the document (e.g., around graphic elements) to accommodate the increased size of the characters.

Claims

1. A method comprising:

providing a document in electronic form;

receiving user input regarding visual impairment; and

in response to one or more levels of visual impairment, automatically changing an appearance of said document,

wherein said changing of said appearance of said document comprises increasing a size of characters in said document.

2. The method in claim 1, wherein said levels of visual impairment comprise one of a predetermined scale, and an optical refraction measurement of said user.

3. The method in claim 1, wherein said changing of said appearance of said document further comprises reformatting said document to accommodate an increased size of said characters.

4. The method in claim 1, wherein said providing of said document comprises scanning said document and performing optical character recognition on scanned documents.

5. The method in claim 1, wherein said changing of said appearance of said document varies depending upon a level of visual impairment of said user.

6. The method in claim 1, further comprising storing a visual impairment level of a first user and automatically performing said changing of said appearance of all documents requested by said first user.

7. A method comprising:

providing a document in electronic form;

receiving user input regarding visual impairment; and

in response to one or more levels of visual impairment, automatically changing an appearance of said document,

wherein said changing of said appearance of said document comprises;

increasing a size of characters in said document;

providing text-to-speech conversion of said document; and

producing audio output of said text-to-speech conversion in coordination with a corresponding portion of said document being displayed.

8. The method in claim 7, wherein said levels of visual impairment comprise one of a predetermined scale, and an optical refraction measurement of said user.

9. The method in claim 7, wherein said changing of said appearance of said document further comprises reformatting said document to accommodate an increased size of said characters.

10. The method in claim 7, wherein said providing of said document comprises scanning said document and performing optical character recognition on scanned documents.

11. The method in claim 7, wherein said changing of said appearance of said document varies depending upon a level of visual impairment of said user.

12. The method in claim 7, further comprising storing a visual impairment level of a first user and automatically performing said changing of said appearance of all documents requested by said first user.

13. A system comprising:

a storage device adapted to store a document in electronic form;

a graphic user interface operatively connected to said storage device, wherein said graphic user interface is adapted to receive user input regarding visual impairment; and

a processor operatively connected to said graphic user interface, wherein said processor is adapted to, in response to one or more levels of visual impairment, automatically change an appearance of said document by increasing a size of characters in said document.

14. The system in claim 13, wherein said levels of visual impairment comprise one of a predetermined scale, and an optical refraction measurement of said user.

15. The system in claim 13, wherein said processor is further adapted to reformat said document to accommodate an increased size of said characters.

16. The system in claim 13, further comprising a scanner operatively connected to said storage device, wherein said scanner is adapted to scan said document, wherein said processor is further adapted to perform optical character recognition on scanned documents.

17. The system in claim 13, wherein said processor is adapted to change said appearance of said document in different ways depending upon a level of visual impairment of said user.

18. The system in claim 13, wherein said storage device is further adapted to store a visual impairment level of a first user and said processor is further adapted to automatically perform said changing of said appearance of all documents requested by said first user.

19. A system comprising:

a storage device adapted to store a document in electronic form;

a graphic user interface operatively connected to said storage device, wherein said graphic user interface is adapted to receive user input regarding visual impairment; and

a processor operatively connected to said graphic user interface, wherein said processor is adapted to, in response to one or more levels of visual impairment, automatically change an appearance of said document by increasing a size of characters in said document;

a text-to-speech converter operatively connected to said processor, wherein said text-to-speech converter is adapted to convert text in said document into spoken words; and

an audio output operatively connected to said text-to-speech converter, wherein said audio output is adapted to, under control of said processor, output said spoken words of said document in coordination with a corresponding portion of said document being displayed.

20. The system in claim 19, wherein said levels of visual impairment comprise one of a predetermined scale, and an optical refraction measurement of said user.

21. The system in claim 19, wherein said processor is further adapted to reformat said document to accommodate an increased size of said characters.

22. The system in claim 19, further comprising a scanner operatively connected to said storage device, wherein said scanner is adapted to scan said document, wherein said processor is further adapted to perform optical character recognition on scanned documents.

23. The system in claim 19, wherein said processor is adapted to change said appearance of said document in different ways depending upon a level of visual impairment of said user.

24. The system in claim 19, wherein said storage device is further adapted to store a visual impairment level of a first user and said processor is further adapted to automatically perform said changing of said appearance of all documents requested by said first user.
