Zusammenfassung:The invention relates to a method and arrangement for creating a virtual keyboard for a terminal ( 800 ) used in a cellular network. The virtual keyboard is generated using an IR transceiver arrangement ( 12 ) in which a reflection from an obstacle ( 15 ) placed in the field of IR transmitters is registered by discrete IR receivers. The received reflection data are processed in a neural network arrangement ( 33 ). The purpose of the data processing is to find out the virtual key position/function that the received reflection data corresponds to.
