Abstract: A touch sensitive film (1) includes a conductive layer (2) having a touch sensing region (3), and a user input surface (4). The user input surface of the touch sensitive film includes a tactilely distinguishable surface feature (5) deviating from the general nature of the user input surface (4) for identifying the location of the touch sensing region (3) by sensing the tactilely distinguishable surface feature.

Abstract: A capacitive touch sensitive film comprises a conductive layer having a sensing region. According to the present invention, the sheet resistance of the conductive layer in the sensing region is higher than or equal to 3 k?.

Abstract: The present invention discloses a touch interface device for numerous applications and also a principle to store the device in a compact form. The device includes a flexible touch sensitive film which can be enclosed into a casing when stored, and removed, either fully or partially, from the casing when in use. The film may be manufactured by using High Aspect Ratio Molecular Structures. Touch Driving, Sensing and Communication Modules, separate or combined, can be attached to the touch sensitive film in order to transmit a raw touch signal to Touch Processing and Communication Modules, either separate or combined, and then as further processed, to a desired CPU or computer. The casing may also house an internal projector for displaying information. Furthermore, haptic feedback can be generated via the touch sensitive film as well.

Abstract: A touch sensor having a touch sensitive film, a signal filter, electrical circuitry and a processing unit. The film is capable of capacitive or inductive coupling to an external object when a touch is made by the object. The signal filter is formed by the resistance of the film and the capacitive or inductive coupling to the external object, and the filter has properties affected by location of the touch and/or capacitance or inductance of the touch. The electrical circuitry is coupled to the touch sensitive film and configured to supply excitation, amplitude and wave form into the signal filter and to receive response signals from the signal filter. The processing unit is configured to detect the presence or proximity of a touch, the location of said touch, the capacitance and/or inductance of said touch by processing response signals and thereby measuring changes in the properties of the signal filter.
