Arrays of resistive elements for use in touch panels and for producing electric fields |
摘要 |
Selected touch point locating apparatus has an array of two or more electrical touch members constituted by impedance elements coupled to a circuit for causing electric current to flow through a selected touch point as the algebraic sum of separate currents through the electrical touch members. The relative amplitudes are translated into at least two signals corresponding to the location in two axes of the selected touch point.
