US Patent 10990204 Virtual touchpad at keyboard location

An information handling system touchscreen display detects touches at a touch detection surface as inputs to the information handling system to report as inputs to an embedded controller. An embedded controller detects placement of a keyboard on the touchscreen display in a forward position and in response commands an infrared position detector to activate to detect finger movement at a virtual touchpad disposed external to the information handling system housing. A microphone disposed proximate the virtual touchpad detects end user taps as inputs and a projector disposed proximate the virtual touchpad illuminates a boundary of the virtual touchpad. When the keyboard is moved from the forward position to a rearward position, a virtual touchpad may be presented on the display and the infrared position detector may be deactivated.
