Information handling system touch detection surface control icon user interface

Keyboard having touch display with control icons

An information handling system may include a processor, a memory, a radio to transceive wirelessly via an antenna with a wireless network, and a touchpad to receive touch input via a surface of the touchpad when the information handling system is detected in a clamshell configuration, where the touch input is received by a touchpad driver and processed to a corresponding touch input command. An orientation sensor to detect when the information handling system is changed to a tablet configuration and a controller to deactivate the touchpad to receive the touch input for processing to a corresponding touch input command and to activate and operatively couple a metallic layer of the touchpad to a proximity sensor integrated circuit to detect when a user's body is close to the antenna to reduce the power for transmission via the antenna to reduce a specific absorption rate (SAR) level.

System and method for multi-function touchpad for human proximity sensing

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.

Information handling system collaborative touchpad display hardware device coordination

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. A gesture at the touchpad in the application area commands presentation and removal of the control icons at the touchpad display in the application area while different touch analysis logic is applied to end user touches in the application area versus the remainder of the touchpad at which cursor inputs are accepted.

Information handling system collaborative touchpad gesture activation and management

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 scales between a first configuration that accepts cursor inputs at the full touch detection surface area and a second configuration that limits cursor inputs to touches in a first portion of the touch detection surface and presents control icons in a second portion, such as by applying different touch analysis logic to end user touches in the first and second portions.

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 or a calculator user interface. The touchpad accepts inputs at the control icons with a predetermined touch, such as a tap or a double tap. The touchpad continues to provide cursor touch inputs across the full touch surface, including over the control icons by applying separate touch logic to isolate control icon inputs, such as isolating finger taps as control icon inputs when control icons are presented.

Information handling system collaborative touchpad display brightness management

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. A cursor touch rejection logic is applied at the touchpad to interpret touches as inputs to the information handling system based upon a presented cursor position. A separate application touch rejection logic is applied to the application area with the control icons are presented.
