Valid x-y pairs are formed based on comparing one or more signal parameters such as signal magnitude, signal strength, signal width, and signal rates of change. In matrix capacitive systems where capacitance-to-ground signals are used to determine the x- and y-coordinates, the determined coordinates may be formed into valid x-y pairs using mutual capacitance measurements. When resolving more than two temporally overlapping touches, information gained by resolving a valid x-y coordinate pair of at least one of the touches may be used to resolve the remaining touches."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for assessing locations of multiple touch inputs","description":"Matrix-based touch input systems assess touch locations of two or more temporally overlapping touch inputs by forming valid x-y coordinate pairs from independently determined x- and y-coordinates.
