1. An input interface, comprising:
- a touch sensor panel having a surface and a first sensor arrangement provided on the surface to sense a position of a touch action with two-dimensional spatial resolution;
a transparent window member offset from the surface of the touch sensor panel in a direction perpendicular to the surface; and
a second sensor arrangement interposed between the surface and the transparent window member, the second sensor arrangement being configured to sense a magnitude of a force normal to the surface applied by the touch action and pushing the window member toward the touch sensor panel.

Abstract
An input interface comprises a touch sensor panel having a surface and a first sensor arrangement provided on the surface to sense a position of a touch action with two-dimensional spatial resolution. A transparent window member is offset from the surface of the touch sensor panel in a direction perpendicular to the surface. A second sensor arrangement is interposed between the surface and the transparent window member. The second sensor arrangement is configured to sense a magnitude of a force normal to the surface applied by the touch action and pushing the window member toward the touch sensor panel.

19. A method of producing an input interface, the method comprising:
-
forming first conductive traces on a central area of a surface of a touch sensor panel to provide a first sensor arrangement to sense a position of a touch action with two-dimensional spatial resolution; forming second conductive traces on a peripheral area of the surface to provide a second sensor arrangement to sense a magnitude of a force applied by the touch action, the peripheral area surrounding the central area of the surface, applying a force sensing material on the second conductive traces; and attaching a transparent window member to the touch sensor panel such that the transparent window member is offset from the touch sensor panel in a direction normal to the surface and that the second sensor arrangement is interposed between the touch sensor panel and the transparent window member. - View Dependent Claims (20)
