Abstract
Official abstract text for this publication.
A system for adjusting an electronic display is provided herein. The system includes a gaze tracking device to capture an image of a pupil associated with a viewer of the electronic display, and a diameter of the pupil being ascertained via the image of the pupil. In another example, the system may also include an ambient light sensor receiver to logarithmically receive light information from an ambient light sensor; and a display adjuster to adjust a luminance of the electronic display based on a combination of a diameter and the light information.
First claim
Opening claim text (preview).
We claim: 1. A system for adjusting an electronic display, comprising: a gaze tracking device to capture an image of a pupil associated with a viewer of the electronic display, and a diameter of the pupil being ascertained via the image of the pupil; an ambient light sensor receiver to logarithmically receive light information from an ambient light sensor; and a display adjuster to adjust a luminance of the electronic display based on a combination of the diameter of the pupil and the light information, wherein the light information is transformed via an analog-to-digital (A/D) process, the light information, after undergoing the A/D process, is combined with a display user bias to produce an output. 2. The system according to claim 1 , wherein the output is combined with a transformed version of the pupil diameter to produce a gain factor. 3. The system according to claim 2 , wherein the gain factor is employed to perform the adjustment of the electronic display. 4. The system according to claim 1 , wherein the diameter of the pupil undergoes a logarithmic transformation. 5. The system according to claim 4 , wherein the logarithmic transformation is defined by an expression relating the La and the D, where La is the luminance per viewing area; and D is the diameter of the pupil. 6. The system according to claim 5 , wherein the logarithmic transformation is further adjusted for an age associated with the pupil. 7. A system for adjusting a heads-up display (HUD), comprising: a gaze tracking device to capture an image of a pupil associated with a viewer of the electronic display, and a diameter of the pupil being ascertained via the image of the pupil; the system is configured to transform the diameter of the pupil with a logarithmic transformation; and a display adjuster to adjust a luminance of the HUD based on transformed diameter of the pupil, wherein the logarithmic transformation is defined by an expression relating the La and the D, where La is the luminance per viewing area; and D is the diameter of the pupil. 8. The system according to claim 7 , wherein the display adjuster adjusts the HUD further by a user bias.
