Abstract
Official abstract text for this publication.
A touch sensor includes conductive elements of substantially concave shape to enable detection of multiple simultaneous touches in at least two directions, with reduced noise sensitivity and enhanced accuracy. The shapes of the conductive elements may be similar, or may be alternating, complementary shapes that cover substantially all of the sensor area. The conductive elements physically interact with adjacent elements in such a way that the area covered by a touch changes monotonically from overlapping substantially all of one element to overlapping substantially all of an adjacent element as the touch area is moved from one element to the other element along a line between the centers of those adjacent elements. Such monotonic change of touch overlap area may occur simultaneously in two orthogonal directions. Connections from internally positioned conductive elements to a touch controller may be made to pass through other conductive elements.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of determining touch locations on a touch sensor having conductive elements connected to a touch controller, the touch controller configured to measure changes in capacitance of each of the conductive elements, the method comprising: (a) selecting a group of conductive elements overlapped by a touch based on the measurements of the touch controller; (b) determining a weighted average of coordinates of centers of each of the conductive elements;…
