static indicating arrangements comprising an association of a number of separate sources or light control cells G09F9/00; static indicating arrangements comprising integral associations of a number of light sources H01J, H01K, H10H, H05B33/12; scanning, transmission or reproduction of documents or the like, e.g. facsimile transmission, details thereof H04N1/00) ## Abstract In one embodiment, a computing device dynamically determines a current viewing direction with respect to a display of the computing device; the computing device also dynamically directs at least some light emitted by at least a portion of the display toward the current viewing direction. ## Claims ### Claim 1 A method comprising: by a computing device, dynamically determining a current viewing direction with respect to a display of the computing device; and by the computing device, dynamically directing at least some light emitted by at least a portion of the display toward the current viewing direction. ### Claim 2 (depends on 1) The method of claim 1, wherein determining the current viewing direction comprises determining an inclination and an azimuth of the current viewing direction. ### Claim 3 (depends on 1) The method of claim 1, wherein directing the light comprises orienting a viewing cone of the display toward the current viewing direction. ### Claim 4 (depends on 1) The method of claim 1, wherein: software on the computing device determines the current viewing direction; and a device driver of the computing device directs the light toward the current viewing direction. ### Claim 5 (depends on 4) The method of claim 4, wherein the software is an operating system of the computing device. ### Claim 6 (depends on 1) The method of claim 1, wherein the light is directed without changing an orientation of the computing device. ### Claim 7 (depends on 1) The method of claim 1, wherein directing the light comprises changing orientation of one or more components of the display that: are one or more sources of the light; the light passes through; or the light reflects off of. ### Claim 8 (depends on 1) The method of claim 1, wherein directing the light comprises collimating the light. ### Claim 9 (depends on 1) The method of claim 1, wherein the current viewing direction is determined at least in part based on a current orientation of the computing device. ### Claim 10 (depends on 1) The method of claim 1, wherein: a user viewing the display comprises eyes; and the current viewing direction is determined at least in part based on a location of the eyes of the user. ### Claim 11 One or more computer-readable non-transitory storage media embodying software that is operable when executed by a computing device to: dynamically determine a current viewing direction with respect to a display of the computing device; and dynamically direct at least some light emitted by at least a portion of the display toward the current viewing direction. ### Claim 12 (depends on 11) The media of claim 11, wherein to determine the current viewing direction, the software if operable when executed by the computing device to determine an inclination and an azimuth of the current viewing direction. ### Claim 13 (depends on 11) The media of claim 11, wherein to direct the light, the software is operable when executed by the computing device to orient a viewing cone of the display toward the current viewing direction. ### Claim 14 (depends on 11) The media of claim 11, wherein: the software determines the current viewing direction; and a device driver of the computing device directs the light toward the current viewing direction. ### Claim 15 (depends on 14) The media of claim 14, wherein the software is an operating system of the computing device. ### Claim 16 (depends on 11) The media of claim 11, wherein the light is directed without changing an orientation of the computing device. ### Claim 17 (depends on 11) The media of claim 11, wherein to direct the light, the software is operable when executed by the computing device to change orientation of one or more components of the display that: are one or more sources of the light; the light passes through; or the light reflects off of. ### Claim 18 (depends on 11) The media of claim 11, wherein to direct the light, the software is operable when executed by the computing device to collimate the light. ### Claim 19 (depends on 11) The media of claim 11, wherein the current viewing direction is determined at least in part based on a current orientation of the computing device. ### Claim 20 (depends on 11) The media of claim 11, wherein: a user viewing the display comprises eyes; and the current viewing direction is determined at least in part based on a location of the eyes of the user.
