Abstract

In a method for displaying visual information (9) on a display surface (3, 13, 20, 21), a display parameter (P) is modified, at trigger intervals, in at least one region of the display surface (3, 13) for a subliminal period of time. The display parameter (P) is preferably selected from the brightness, colour, illumination, contrast, focus, frequency or connection/disconnection of the display. By said measure, a viewer of the display surface (3) is prompted to perform a blinking movement which leads to the moistening of the eye with tear fluid and thereby prevents eye irritation without the viewer consciously perceiving the externally controlled blinking.

Claims

1. A method for displaying visual information on a display surface, wherein a display parameter is modified, at trigger intervals, in at least one region of the display surface for a subliminal period of time which is below the human perception threshold.

2. The method according to claim 1, wherein the display parameter is selected from the brightness, colour, illumination, contrast, focus, frequency or connection/disconnection of the display.

3. The method according to claim 1 wherein the subliminal period of time is determined to be 0.06 seconds at the most.

4. The method according to claim 1, wherein the subliminal period of time is adjustable.

5. The method according to claim 1, wherein, at time intervals which are larger than the trigger intervals, the display parameter is modified in at least one region of the display surface for an optionally adjustable supraliminal period of time which is above the human perception threshold.

6. The method according to claim 1, wherein the trigger interval is adjustable to a value or a value profile by a user or a random generator, with the variability of the trigger interval preferably lying within predetermined limits.

7. The method according to claim 1, wherein the display surface is integral with a display and the modification of the display parameter is caused by changing the control of the display.

8. The method according to claim 1, wherein the display surface is a projection surface or a support surface provided with the visual information and the modification of the display parameter comprises irradiating the display surface with light from a source of light or a projector for the subliminal period of time.

9. The method according to claim 1, wherein a display parameter is modified in such a region of the display surface in which a cursor, a mouse pointer, an input field, an active screen window or another indicator attracting the viewer'"'"'s attention is located.

10. The method according to claim 1, wherein a display parameter is modified in such a region of the display surface on which the viewer'"'"'s attention detected via attention detection means such as iris identification is focused.

11. The method according to claim 1, which is processed in a computer with an operating system that allows the display of several superimposed display levels on a display surface, wherein a transparent region is provided as the uppermost display level, which transparent region is switched, for the subliminal period of time, into a mode which is not entirely transparent according to the display parameter.

12. The method according to claim 11, wherein the operating system of the computer is designed for the display of display windows, wherein a transparent window is placed over at least one area of the visual information and the transparent window is switched, for the subliminal period of time, into a mode which is not entirely transparent according to the display parameter.

13. The method according to claim 11, wherein the operating system of the computer is designed for the display of several display windows of which one display window is selectable as an active display window acted upon by user inputs, wherein a display parameter is modified in the active window.

14. The method according to claim 11, which is processed in a computer with an operating system that allows the display of several superimposed display windows on a display surface, wherein the modification of a region of the display surface is effected by means of a window faded in for the subliminal period of time and exhibiting display properties which have been predetermined by the display parameter.

15. A computer program product which is suitable for displaying visual information on a display surface and which is loadable directly into a memory of a computer and comprises software code portions, whereby the method according to claim 1 can be processed by means of the computer if the computer program product is processed on the computer.

16. The computer program product according to claim 15, wherein the computer program product is stored on a computer-readable medium.

17. A computer comprising an arithmetic unit and an internal memory which processes the computer program product according to claim 15.

18. A display system comprising a display and at least one display device which shows visual information on a display surface of the display, wherein display modifying means act upon the display device which display modifying means are designed for modifying, at trigger intervals, a display parameter in at least one region of the display surface for a subliminal period of time which is below the human perception threshold.

19. The display system according to claim 18, wherein the display parameter is selected from the brightness, colour, illumination, contrast, focus, frequency or connection/disconnection of the display.

20. The display system according to claim 18, wherein the subliminal period of time is determined to be 0.06 seconds at the most.

21. The display system according to claim 18, wherein the subliminal period of time is adjustable.

22. The display system according to claim 18, wherein, at time intervals which are larger than the trigger intervals, the display parameter is modified in at least one region of the display surface for an optionally adjustable supraliminal period of time which is above the human perception threshold.

23. The display system according to claim 18, wherein the trigger interval is adjustable to a value or a value profile by a user or a random generator, with the variability of the trigger interval preferably lying within predetermined limits.

24. The display system according to claim 18, wherein the position and/or the size of the region of the display surface which is modified is/are variable.
