Abstract
An information handling system touchpad includes an application area with a display to present control icons of an application executing on the information handling system, such as camera and microphone icons to control camera and microphone functions of a videoconference application. The touchpad dynamically adjusts touchpad display brightness and color based upon ambient light conditions detected by an ambient light sensor. Touchpad display brightness control is set independent of main display and keyboard backlight illumination brightness.
Claims21
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions to process information;
- a memory interfaced with the processor and operable to store the instructions and information;
- a display included in the housing and interfaced with the processor, the display operable to present the information as visual images;
- a persistent storage device having memory storing an operating system and an application configured to execute as instructions on the processor;
- an embedded controller interfaced with the processor and operable to manage interactions of the processor and other devices;
- an ambient light sensor operable to detect ambient light conditions, the ambient light conditions applied to adjust a brightness of the visual images presented at the display;
- a touchpad included in the housing and having a touch detection surface, a processing resource, a touchpad display and a non-transitory memory interfaced with the processing resource;
- and
- instructions stored in the non-transitory memory that when executed on the processing resource cause the touchpad touch detection surface to detect cursor movement inputs and to selectively present control icons of the application at the touchpad display having a brightness set based at least in part by the detected ambient light conditions,
- wherein the detected ambient light conditions are converted to values used to adjust the brightness of the visual images by converting an ambient light sensor count to LUX values, and
- wherein the LUX values are changed to match the human eye and adjusted until a match is accomplished.
A method for presenting visual images at a touchpad display, the method comprising:
- presenting visual images at a display of the information handling system;
- adjusting the display brightness based upon ambient light conditions sensed by an ambient light sensor;
- presenting visual images with a touchpad display of a touchpad included in the information handling system;
- and
- adjusting the brightness presented by the touchpad display based upon the ambient light conditions;
- wherein the sensed ambient light conditions are converted to values used to adjust the brightness of the visual images by converting an ambient light sensor count to LUX values, and
- wherein the LUX values are changed to match the human eye and adjusted until a match is accomplished.
A touchpad comprising:
- a touch detection surface;
- a touchpad display disposed to present visual images at the touch detection surface;
- a processing resource interfaced with the touch detection surface and touchpad display;
- and
- a non-transitory memory interfaced with the processing resource and storing instructions that when executed on the processing resource cause the touchpad touch detection surface to detect cursor movement inputs and to selectively present control icons of the application at the touchpad display having a brightness set based at least in part by ambient light conditions detected by an ambient light sensor;
- wherein the detected ambient light conditions are converted to values used to adjust the brightness of the visual images by converting an ambient light sensor count to LUX values, and
- wherein the LUX values are changed to match the human eye and adjusted until a match is accomplished.
