1. A touch sensitive film (1) comprising:
a conductive layer (2) having a touch sensing region (3) and an immediately adjacent surrounding area, and a user input surface (4) within the touch sensing region (3), the user input surface (4) comprising a touch sensitive film that defines a touch sensing electrode that is configured to serve as a touch-based user interface where, upon touch of a user's finger or stylus and without movement of the user input surface (4), changes electrical properties of an electrical measuring circuitry to which the user input surface (4) is connected, wherein the touch sensing electrode within the touch sensing region (3) and the user input surface (4) comprises a tactilely distinguishable surface feature (5, 14, 15) that, when touched by a user, provides the user with a first tactile feel, wherein the conductive layer at the tactilely distinguishable surface feature, in cross section view, has an upper surface and a lower surface, the upper surface having a first contour line that includes plural adjacent upward protuberances and the lower surface having a second contour line that matches the first contour line of the upper surface and includes plural adjacent upward protuberances at locations matching the upward protuberances of the first contour line, wherein the surrounding area immediately adjacent the touch sensing region (3) has a surface that is free of the upward protuberances and, when touched by a user, provides the user with a second tactile feel, the first and second tactile feels being different such that the user recognizes the tactilely distinguishable surface feature (5, 14, 15) as tactilely deviating from the immediately adjacent surrounding area of the user input surface, the tactilely distinguishable surface feature (5, 14, 15) thereby identifying the location of the touch sensing region (3) and the user input surface (4). |
