1. An apparatus for a user interface of an electronic device, the apparatus comprising:
a textured surface attached along a viewable side on a display screen of the electronic device, the textured surface having a predetermined roughness and the textured surface is transparent, wherein the textured surface comprises a structural configuration of fingerprint swirls and includes a coating having one or more of the following properties; hydrophobic or oleophobic, the textured surface includes a plurality of actuating elements, each actuating element configured such that the height of the actuating element can be varied independently of the other actuating elements to enable the roughness of the textured surface to be modified, the textured surface is configurable to produce a first predefined vibration in the skin of a first user of the apparatus on physical interaction when the skin of the first user contacts the textured surface and a second predefined vibration in the skin of a second user of the apparatus on physical interaction when the skin of the second user contacts the textured surface, wherein the roughness of the textured surface is configurable to a first user configuration such that the first predefined vibration produced by the physical interaction has a frequency and/or amplitude which is detectable by a specific mechanical receptor in the skin of the first user wherein the frequency and/or amplitude corresponds to the following type of mechanical receptor: Merkel discs, wherein the roughness of the textured surface is configurable to a second user configuration such that the second predefined vibration produced by the physical interaction has a frequency and/or amplitude which is detectable by a different specific mechanical receptor in the skin of the second user, where the apparatus is adapted to be reconfigurably switched between the first user configuration and the second user configuration; and a capacitive element configured to allow establishment of an electric field of varying strength between the capacitive element and a user of the apparatus, variations in electric field strength configured to interact with the skin of the user to produce another predefined vibration in the skin of the user independently of the textured surface. |
