1. A device configured to acquire tactile information, that can be placed over a display device, comprising:

  • a transparent tactile matrix sensor having rows and columns of conductive stripes, the rows arranged next to each other to form a first layer, and the columns are arranged next to each other to form a second layer, and a transparent resistive layer arranged between the first layer of rows and the second layer of columns, a resistivity of the transparent resistive layer decreasing as a function of a pressure that is exerted onto the transparent resistive layer; and

    a measurement unit configured to measure an electric resistance for each overlap area of a column and a row that are separated from each other by the transparent resistive layer to acquire information on a pressure force at the respective overlap area to acquire the tactile information.
