Input device for entering characters or control instructions into communication unit has measuring elements and counter elements that are dimensioned in and arranged relative to one another on cylindrical body or on selection element

摘要

The measuring elements (6) and the counter elements (7) are dimensioned in such a way and arranged relative to one another on the cylindrical body (4) or on the selection element (5) in such a way that mutually differing capacitance values (C1, C2, C3) are picked off at least one of the measuring elements as a function of the relative position. The measuring elements which capacitively detect at least two charges on the cylindrical body or the selection element. Independent claims are included for the following: (1) a method for entering characters or control instructions; and (2) a computer program.
