Abstract

An audible indicator such as an audio tone is associated with the importance of data elements displayed on a visual display screen of data processing apparatus such as a personal computer or work station. At least one characteristic of the audible indicator, for example its pitch or frequence of a tone, is associated with the importance of the data elements. When a user selects a particular date element on the screen, for example using a computer mouse, the audible indicator conveys the importance of the selected data element to the user. This enables visually impaired users to readily locate important data elements on a display screen without reading the entire screen using a screen reader.

Claims

1. A method for conveying the importance of display screen data, comprising the steps of:

identifying a data element selected by a user on a visual display screen;

determining the importance of the identified data element; and

providing an audible indicator to convey the importance of the identified data element to the user.

2. The method of claim 1, wherein the data element is identified according to a screen location indicated by a computer mouse operated by the user.

3. The method of claim 1, wherein the data element is identified according to a screen location indicated by a computer track ball operated by the user.

4. The method of claim 1, wherein the data element is identified according to a screen location indicated by a computer touch pad operated by the user.

5. The method of claim 1, wherein the data element is identified according to a tab key operated by the user.

6. The method of claim 1, wherein the data element is identified according to position keys operated by the user.

7. The method of claim 1, wherein the data element is identified according to instructions spoken by the user.

8. The method of claim 1, wherein the data element is a form field that accepts input from the user.

9. The method of claim 1, wherein the importance of the data element is determined by reading an encoding that explicitly gives the importance.

10. The method of claim 1, wherein the importance of the data element is determined by reading an encoding and deducing the importance from the read encoding.

11. The method of claim 10, wherein the encoding indicates a display color.

12. The method of claim 1, wherein the audible indicator is selected from the set of audible indicators that consists of an audio tone whose pitch varies in dependence upon the importance of the identified data element, a periodic train of audible clicks with a period that varies in dependence upon the importance of the identified data element, an audio signal that varies between a plurality of audible tones at a rate that depends upon the importance of the identified data element, and an audio signal that varies between two audible tones at a rate that depends upon the importance of the identified data element wherein one of the two tones is essentially silent and the other is not, so as to convey a periodic train of audible beeps to the user with a period that varies in dependence upon the importance of the data element.

13. The method of claim 1, wherein the audible indicator alternates between a plurality of tones of different frequencies, where the rate of alternation is proportional to the importance of a data element and wherein one of the tones conveys a distance between a present location of a screen cursor and the data element.

14. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for conveying the importance of display screen data, said method steps comprising:

identifying a data element selected by a user on a visual display screen;

determining the importance of the identified data element; and

providing an audible indicator to convey the importance of the identified data element to the user.

15. The program storage device of claim 14, wherein the data element is identified according to a screen location indicated by a computer mouse operated by the user.

16. The program storage device of claim 14, wherein the data element is identified according to a screen location indicated by a computer track ball operated by the user.

17. The program storage device of claim 14, wherein the data element is identified according to a screen location indicated by a computer touch pad operated by the user.

18. The program storage device of claim 14, wherein the data element is identified according to a tab key operated by the user.

19. The program storage device of claim 14, wherein the data element is identified according to position keys operated by the user.

20. The program storage device of claim 14, wherein the data element is identified according to instructions spoken by the user.

21. The program storage device of claim 14, wherein the data element is a form field that accepts input from the user.

22. The program storage device of claim 14, wherein the importance of the data element is determined by reading an encoding that explicitly gives the importance.

23. The program storage device of claim 14, wherein the importance of the data element is determined by reading an encoding and deducing the importance from the read encoding.

24. The program storage device of claim 23, wherein the encoding indicates a display color.
