INPUT INTERFACE, PORTABLE ELECTRONIC DEVICE AND METHOD OF PRODUCING AN INPUT INTERFACE

摘要

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.
