Abstract

A data processing system for overcoming at least one vision impairment of a user, comprising a control unit connected to a display, wherein the control unit is arranged to distort a images in relation to the vision impairment and predefined criteria, and to display the distorted images on the display, such that the user suffering from the vision impairment perceives the distorted images as a healthy user perceives the original images. The distortion is continuously and dynamically adjusted in relation to spatial and temporal dimensions of the original images and of objects therein. Vision impairments compensated for may comprise astigmatism; myopia; hyperopia; presbyopia; and color blindness. The display may comprise a watch, a mobile device display, a phone handset, a screen of any type, a transparent material, such as a window, or a reflecting material such as a mirror.

Claims

1. A data processing system for overcoming at least one vision impairment of a user, comprising a control unit connected to a display, wherein the control unit is arranged to distort a plurality of original images in relation to the at least one vision impairment and predefined criteria, and to display the distorted images on the display, such that the user suffering from the at least one vision impairment perceives the distorted images as a healthy user perceives the original images.

2. The data processing system of claim 1, wherein the distortion is continuously and dynamically adjusted in relation to spatial and temporal dimensions of the original images and of objects therein.

3. The data processing system of claim 1, wherein the distortion is carried out on a section of the original images.

4. The data processing system of claim 1, wherein the at least one vision impairment comprises color blindness and wherein the distortion comprises adjusting colors in the original images such as to allow the user differentiate predefined colors in the original images.

5. The data processing system of claim 1, wherein the at least one vision impairment comprises astigmatism, and the control unit is arranged to compensate for regular and for irregular defects.

6. The data processing system of claim 1, wherein the at least one vision impairment comprises myopia, and the control unit is arranged to compensate for blurring of seemingly distant objects in the original images.

7. The data processing system of claim 1, wherein the at least one vision impairment comprises hyperopia, and the control unit is arranged to allow the user to clearly perceive seemingly near objects in the original images.

8. The data processing system of claim 1, wherein the at least one vision impairment comprises presbyopia, and the control unit is arranged to allow the user to clearly perceive seemingly near objects in the original images.

9. The data processing system of claim 1, wherein the display is a mobile device display.

10. The data processing system of claim 1, wherein the display is a screen.

11. The data processing system of claim 1, wherein the display is associated with a transparent material.

12. The data processing system of claim 11, wherein the display is associated with a vehicle window, and wherein the data processing system extends a field of view of the user driving the vehicle.

13. The data processing system of claim 1, wherein the display is associated with a reflecting material.

14. The data processing system of claim 1, wherein the control unit is further arranged to receive user defined characteristics of the at least one vision impairment.

15. The data processing system of claim 1, further comprising a feedback module arranged to present the user with a plurality of predefined calibration images and receive from the user input relating to the perceived clarity of the predefined calibration images, wherein the feedback module is arranged to calculate at least one distortion parameter from user input and adjust the distortion applied by the control unit to the original images accordingly.

16. The data processing system of claim 1, further comprising a calibration module arranged to adjust the distortion applied by the control unit according to optical measurements carried out on at least one visual aid used by the user.

17. The data processing system of claim 16, wherein the calibration module is arranged to measure image characteristics of a plurality of predefined calibration images as viewed through the at least one visual aid and calibrate the control unit in relation to the measured image characteristics in respect to characteristics of the predefined calibration images.

18. The data processing system of claim 1, wherein the data processing system is arranged to receive the original images from a display processor, and wherein the control unit is arranged to distort the received original images and display the distorted images on the display substantially immediately after their receipt.

19. A computer-implemented method of overcoming at least one vision impairment of a user, comprising:

receiving a plurality of original images;

distorting the original images in relation to the at least one vision impairment and predefined criteria, and

displaying the distorted images, such that the user suffering from the at least one vision impairment perceives the distorted images as a healthy user perceives the original images.

20. The computer-implemented method of claim 19, further comprising measuring characteristics of the at least one vision impairment and distorting the original images in relation thereto.
