SYSTEM FOR DETECTING AND CHARACTERIZING TOUCH INPUTS AT A HUMAN-COMPUTER INTERFACE

A system includes: a substrate including an edge supported by a chassis; a first electrode spanning a first area of the substrate and arranged proximal a center of the substrate; and a second electrode spanning a second area, greater than the first area, on the substrate and interposed between the f...

More Information
Summary:A system includes: a substrate including an edge supported by a chassis; a first electrode spanning a first area of the substrate and arranged proximal a center of the substrate; and a second electrode spanning a second area, greater than the first area, on the substrate and interposed between the first electrode and the edge of the substrate. The system further includes a first coupling region: facing the first electrode; and electrically coupling to the first electrode to yield a first electrical value at the first electrode responsive to application of a first force magnitude proximal the center of the substrate. The system also includes a second coupling region: facing the second electrode; and electrically coupling to the second electrode to yield a second electrical value, approximating the first electrical value, at the second electrode responsive to application of the first force magnitude proximal the center of the substrate.
