Abstract: An electronic reading device includes an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device includes circuitry configured to receive a low ambient light preferred brightness level, receive a high ambient light preferred brightness level, and set a rate at which a brightness level transitions between the low ambient light preferred brightness level and the high ambient light preferred brightness level as the ambient light changes.

Abstract: An electronic device includes an adjustable RGBW front light. The electronic device additional includes circuitry configured to determine if a transition between phases has occurred, the phases being based on a time of day, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the predetermined screen color temperature does not change in response to a change in a brightness level of the electronic device.

Abstract: An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to receive a signal from the ambient light sensor corresponding to a detected ambient light level, automatically display a default brightness level based on the detected ambient light level, determine if the brightness level is manually adjusted, automatically adjust the relative brightness based on the manually adjusted brightness level when the ambient light level changes, and update preferred relative settings to correspond to the manual adjustment.

Abstract: An electronic reading device includes an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device includes circuitry configured to receive a signal corresponding to a brightness level from the ambient light sensor, receive a signal corresponding to a current screen color temperature, calculate a predetermined mixture of light based on at least one of the brightness level or the current screen color temperature, Wherein the calculation allows the current screen color temperature to remain the same regardless of the brightness level, and display the predetermined mixture of light via the adjustable RGBW front light.

Abstract: A computing device includes a housing and a display assembly having a screen. The housing at least partially circumvents the screen so that the screen is viewable and a set of touch sensors are provided with the display assembly. A processor is provided within the housing to detect a gesture via the set of touch sensors, and to interpret the gesture as one of a plurality of user inputs. The processor further detects a presence of extraneous objects on a surface the screen of the display assembly, and adjusts one or more settings of the computing device in response to detecting the presence of extraneous objects. For example, the processor may adjust the one or more settings by reconfiguring a set of actions to be performed in response to the plurality of user inputs.
