摘要： An expansion device couples to a capacitive mat disposed on a desktop surface and communicates power and data through the capacitive mat to perform functions in support of an information handling system. For example, the expansion device powers an inductive charger to charge a peripheral device, accepts end user touch inputs with a capacitive touch sensor, presents visual information at an integrated display in response to pixel values provided by the information handling system though the capacitive mat.

摘要： A portable information handling system rotationally couples main and lid housing portions to each other with a hinge having opposing faces. One of a first or second antenna set disposed on the opposing faces is selected to support wireless communication by a radio disposed in the housing based upon the rotational orientation of the hinge. Optimal antenna selection is confirmed by comparing return signal strength indicator or bit rate error of the first and second antenna sets.

摘要： Identifying characteristics integrated in a totem and detected by a capacitive display mat are applied to perform functions in response to end user inputs. Identifying characteristics include capacitive feet integrated in a totem bottom surface with identifying features including varying capacitive values for the feet, varying pad sizes and shapes, varying pad patterns and varying capacitive oscillation frequencies. In one embodiment, the surface area of the totem in contact with the capacitive mat varies depending upon the pressure placed on the totem to alter the shape of a compressible material disposed at the bottom surface.

摘要： Desktop surface references are selected and applied to define a coordinate system for calibrating projected visual images and end user inputs at the projected visual images. For example, a desktop edge is detected with the depth camera by the increase in detected distance along the axis from the depth camera to the desktop edge, and then the desktop edge is used as an origin for a coordinate system that defines a projection area for presenting a user interface. Monitoring end user inputs and projected outputs relative to the desktop edge aids in coordinating interactions by a user through the projected user interface in the event the camera or projector move relative to the desktop surface.
