1. A device comprising:
- a display configured to present content;
one or more input devices;
one or more light emitters configured to illuminate the display; and
a processor configured to;
present the content using the display with a first display output mode operating the one or more light emitters using a first intensity curve of light emissions across a first portion and a second portion of a range of wavelengths from about 380 nanometers to 570 nanometers;
receive one or more user inputs from the one or more input devices;
generate usage data based on the one or more user inputs, wherein the usage data is indicative of a time-of-day of ending presentation of content on the display; and
based at least in part on the usage data, transition over a period of time of at least five minutes to a second display output mode operating the one or more light emitters to generate a second intensity curve of light emissions having a second intensity of light emissions across the first portion of the range of wavelengths that is less than the first intensity curve and having the second intensity of light emissions across the second portion of the range of wavelengths being the same as the first intensity curve.

Abstract
Illumination of a display is controlled so as to modulate the intensity of emissions in one or more spectral ranges over time while content is being presented. Usage data indicative of user interaction with the presented content or previously presented content can be used to generate or modify a pattern profile. The pattern profile is used to control light emitters of a media device. Various operating modes respectively directed to decreasing or increasing intensity over time within certain portions of the visible spectrum can be used during the presentation of written, video or other content.

5. A system, comprising:
-
a server configured to; receive usage data from a media device, wherein the usage data is indicative of consumption by a user of content comprising an electronic book; derive a pattern profile by way of the usage data; provide at least one or more of the usage data or the pattern profile to a media device; and a media device including a display and an illumination resource and a controller, the controller configured to; present the content on the display; provide usage data to the server, the usage data corresponding to the user interaction with content presented on the display; receive the pattern profile from the server, wherein the pattern profile specifies a transition over time from a first output mode to a second output mode; and control, based at least in part on the pattern profile, one or more of the display or the illumination resource to change from using a first intensity curve of light emissions across a first portion and a second portion of spectral range while content is being presented on the display to a second intensity curve having a second intensity of light emissions across the first portion of the spectral range that differs from the first intensity curve while having the second intensity of light emissions across the second portion of the spectral range being the same as the first intensity curve. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A non-transitory computer-readable storage media including a program code, the program code configured to cause one or more processors to:
-
derive usage data corresponding to user interaction with viewable content presented by a media device, wherein the user interaction comprises a page turn of an electronic book and the usage data is indicative of a page turn rate; present viewable content using the media device; and modulate illumination intensity of the media device within a first portion of a predetermined spectral range between an initial magnitude of light intensity and a terminal magnitude of light intensity over a period of at least five minutes while the initial magnitude of light intensity across a second portion of the predetermined spectral range remains the same, the modulation performed in accordance with the usage data and a pattern profile during the presentation of viewable content. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
