Abstract
Various techniques are provided for reducing the impact of tangential forces on touch location in a touch location device. For example, in one aspect, shunt connections are provided that impede lateral motion of the touch surface structure at the level of the touch plane, thereby reducing to insignificant magnitude reactions to tangential force passing through the sensing connections. In another aspect, sensing connections incorporate elastic means so adjusted as to turn that connection's reaction to tangential touch force perpendicular to its axis of sensitivity. In another aspect, sensing connections incorporate sensing means so adjusted as to turn that connection's axis of sensitivity perpendicular to its reaction to tangential force.
