Abstract

End user interactions at a display are monitored for predetermined conditions to provide augmentation of display presentation by a red light that illuminates in the 650 to 800 nm range, such as at substantially 670 nm. Instructions stored in non-transient memory and executed on a processor present visual images of varied color contrast and evaluate end user inputs to determine an end user visual acuity. Over time and use of the display and red light, end user visual acuity is periodically tested to evaluate the effectiveness of red light illumination to restore visual acuity.

First claim

What is claimed is:

1. A method for augmentation of presentation of visual information at a display of an information handling system, the method comprising:
processing information with an operating system and applications executing on a processor that generate the visual information;
presenting the visual information as visual images at the display with illumination by the display, the visual images including active presentations and inactive presentations;
monitoring end user interactions at the display with an operating system driver that evaluate end user visual acuity; and
in response to a predetermined level of end user interactions, initiating red light illumination of red light with a red light source integrated in the information handling system display and having a 650 to 800 nm spectral range, the red light source separate from the illumination of the display associated with presentation of the visual images at the display, the red light source illumination presented when the visual information is inactive presentations.

2. The method of claim 1 wherein the red light emits at 670 nm.

3. The method of claim 1 wherein the red light comprises plural light emitting diodes (LEDs) of different colors, the method further comprising:
selectively illuminating all of the plural LEDs to generate white light; and
selectively illuminating only red LEDs of the plural LEDs to generate the red light.

4. The method of claim 1 wherein the monitoring interactions further comprises monitoring for eye gaze of the end user directed at the display.

5. The method of claim 1 wherein the monitoring interactions further comprises monitoring the end user distance to the display.

6. The method of claim 1 further comprising:
performing plural tests over time of the end user's visual acuity by presenting visual images at the display having predetermined color contrast and evaluating the end user's inputs that indicate recognition of the color contrast; and
evaluating the effect of the illumination of red light based upon changes in the end user's visual acuity over the time.

7. A system for augmenting display interactions, the system comprising:
a light operable to present red light in a 650 to 800 nm spectral range;
a non-transient memory storing instructions that, when executed on a processor, cause:
monitoring of an end user's interactions at a display that presents information as visual images that include active presentations and inactive presentations, the display separate from the light; and
illumination of the red light by the light at the display in response to one or more predetermined conditions including at least a predetermined level of the end user's interactions, the red light presented when the visual information is the inactive presentations and not when the visual information is the active presentations.

8. The system of claim 7 wherein the light further comprises:
plural light emitting diodes (LEDs) of different colors that simultaneously illuminate to create white light, at least one of the plural LEDs illuminating the red light; and
a controller operable to selectively command the white light and the red light.

9. The system of claim 7 wherein the instructions when executed on the processor further cause:
performing plural tests over time of the end user's visual acuity by presenting visual images at the display having predetermined color contrast and evaluating the end user's inputs that indicate recognition of the color contrast; and
evaluating the effect of the illumination of red light based upon changes in the end user's visual acuity over the time.

10. The system of claim 7 wherein the predetermined level of end user interactions comprises interactions measured by end user presence at the display and end user distance to the display.
